104-618: Pamban Island ( Tamil : பாம்பன் தீவு , pāmpaṉ tīvu ), also known as Rameswaram Island , is an island located between peninsular India and Sri Lanka . It forms part of the Rameswaram taluk in the Ramanathapuram district of the Indian state of Tamil Nadu . It is the largest island in Tamil Nadu by area and the principal town in the island is the pilgrimage centre of Rameswaram . Pamban Island

208-468: A lexical root to which one or more affixes are attached. Most Tamil affixes are suffixes . Tamil suffixes can be derivational suffixes, which either change the part of speech of the word or its meaning, or inflectional suffixes, which mark categories such as person , number , mood , tense , etc. There is no absolute limit on the length and extent of agglutination , which can lead to long words with many suffixes, which would require several words or

312-480: A , as with other Indic scripts . This inherent vowel is removed by adding a tittle called a puḷḷi , to the consonantal sign. For example, ன is ṉa (with the inherent a ) and ன் is ṉ (without a vowel). Many Indic scripts have a similar sign, generically called virama , but the Tamil script is somewhat different in that it nearly always uses a visible puḷḷi to indicate a 'dead consonant' (a consonant without

416-740: A 2001 survey, there were 1,863 newspapers published in Tamil, of which 353 were dailies. Tamil is the primary language of the majority of the people residing in Tamil Nadu , Puducherry , (in India) and in the Northern and Eastern provinces of Sri Lanka . The language is spoken among small minority groups in other states of India which include Karnataka , Telangana , Andhra Pradesh , Kerala , Maharashtra , Gujarat , Delhi , Andaman and Nicobar Islands in India and in certain regions of Sri Lanka such as Colombo and

520-560: A big influence on soil temperature. Draper et al. (1985), for instance, documented this as well as the effect it had on root growth of outplants (Table 30). The mounds warmed up quickest, and at soil depths of 0.5 cm and 10 cm averaged 10 and 7 °C higher, respectively, than in the control. On sunny days, daytime surface temperature maxima on the mound and organic mat reached 25 °C to 60 °C, depending on soil wetness and shading. Mounds reached mean soil temperatures of 10 °C at 10 cm depth 5 days after planting, but

624-472: A broadcast slash fire in a clearcut does not give a uniform burn over the whole area. Tarrant (1954), for instance, found only 4% of a 140-ha slash burn had burned severely, 47% had burned lightly, and 49% was unburned. Burning after windrowing obviously accentuates the subsequent heterogeneity. Marked increases in exchangeable calcium also correlated with the amount of slash at least 7 cm in diameter consumed. Phosphorus availability also increased, both in

728-511: A family of around 26 languages native to the Indian subcontinent . It is also classified as being part of a Tamil language family that, alongside Tamil proper, includes the languages of about 35 ethno-linguistic groups such as the Irula and Yerukula languages (see SIL Ethnologue ). The closest major relative of Tamil is Malayalam ; the two began diverging around the 9th century CE. Although many of

832-578: A few churches. The township is also served by a police station. Ekantharamar Temple constructed and maintained by the Kanchi mutt is the main attraction here. At the eastern tip of the island lies the site of Dhanushkodi , a harbour and a pilgrimage centre, which was washed away by the December 1964 cyclone . Prior to its destruction it was a flourishing township and a prominent place of pilgrimage. In its heyday, it rivalled Rameswaram in size and population. However,

936-448: A general deterioration in site productivity; Endean and Johnstone (1974) describe experiments to test prescribed burning as a means of seedbed preparation and site amelioration on representative clear-felled Picea/Abies areas. Results showed that, in general, prescribed burning did not reduce organic layers satisfactorily, nor did it increase soil temperature, on the sites tested. Increases in seedling establishment, survival, and growth on

1040-591: A number of apparent Tamil loanwords in Biblical Hebrew dating to before 500 BCE, the oldest attestation of the language. Old Tamil is the period of the Tamil language spanning the 3rd century BCE to the 8th century CE. The earliest records in Old Tamil are short inscriptions from 300 BCE to 700 CE. These inscriptions are written in a variant of the Brahmi script called Tamil-Brahmi . The earliest long text in Old Tamil

1144-650: A number of skeletons were found buried in earthenware urns dating from at least 696 BCE in Adichanallur . Some of these urns contained writing in Tamil Brahmi script, and some contained skeletons of Tamil origin. Between 2017 and 2018, 5,820 artifacts have been found in Keezhadi . These were sent to Beta Analytic in Miami , Florida , for Accelerator Mass Spectrometry (AMS) dating. One sample containing Tamil-Brahmi inscriptions

1248-512: A number of sound changes, in particular, a tendency to lower high vowels in initial and medial positions, and the disappearance of vowels between plosives and between a plosive and rhotic. Contact with European languages affected written and spoken Tamil. Changes in written Tamil include the use of European-style punctuation and the use of consonant clusters that were not permitted in Middle Tamil. The syntax of written Tamil has also changed, with

1352-683: A rough surface finish, whereas secondary tillage tends to produce a smoother surface finish, such as that required to make a good seedbed for many crops. Harrowing and rototilling often combine primary and secondary tillage into one operation. "Tillage" can also mean the land that is tilled. The word "cultivation" has several senses that overlap substantially with those of "tillage". In a general context, both can refer to agriculture. Within agriculture, both can refer to any kind of soil agitation. Additionally, "cultivation" or "cultivating" may refer to an even narrower sense of shallow, selective secondary tillage of row crop fields that kills weeds while sparing

1456-512: A sentence in English. To give an example, the word pōkamuṭiyātavarkaḷukkāka (போகமுடியாதவர்களுக்காக) means "for the sake of those who cannot go" and consists of the following morphemes : போக pōka go முடி muṭi accomplish Tillage Tillage that is deeper and more thorough is classified as primary, and tillage that is shallower and sometimes more selective of location is secondary. Primary tillage such as ploughing tends to produce

1560-549: A significantly higher volume (329 cm ) than open plantations (204 cm ). Wang et al. (2000) recommended that sheltered plantation site preparation should be used. Up to 1970, no "sophisticated" site preparation equipment had become operational in Ontario, but the need for more efficacious and versatile equipment was increasingly recognized. By this time, improvements were being made to equipment originally developed by field staff, and field testing of equipment from other sources

1664-459: A similar sturdy animal. Horses are generally unsuitable, though breeds such as the Clydesdale were bred as draft animals. Tilling could at times be very labor-intensive. This aspect is discussed in the 16th-century French agronomic text written by Charles Estienne : A raw, rough, and tough soil is hard to till and will neither bring forth corn, nor any other thing without great labor, however

1768-620: A small number speak the language. In Reunion where the Tamil language was forbidden to be learnt and used in public space by France it is now being relearnt by students and adults. Tamil is also spoken by migrants from Sri Lanka and India in Canada , the United States , the United Arab Emirates , the United Kingdom , South Africa , and Australia . Tamil is the official language of

1872-595: A subject of study in schools in the French overseas department of Réunion . In addition, with the creation in October 2004 of a legal status for classical languages by the Government of India and following a political campaign supported by several Tamil associations, Tamil became the first legally recognised Classical language of India. The recognition was announced by the contemporaneous President of India , Abdul Kalam , who

1976-657: A table of slash weight and size distribution on one acre of a hypothetical stand of white spruce. When the diameter distribution of a stand is unknown, an estimate of slash weight and size distribution can be obtained from average stand diameter, number of trees per unit area, and merchantable cubic foot volume. The sample trees in Kiil's study had full symmetrical crowns. Densely growing trees with short and often irregular crowns would probably be overestimated; open-grown trees with long crowns would probably be underestimated. The need to provide shade for young outplants of Engelmann spruce in

2080-458: A variety of dialects that are all collectively known as Brahmin Tamil . These dialects tend to have softer consonants (with consonant deletion also common). These dialects also tend to have many Sanskrit loanwords. Tamil in Sri Lanka incorporates loan words from Portuguese , Dutch , and English. In addition to its dialects, Tamil exhibits different forms: a classical literary style modelled on

2184-438: A vowel). In other Indic scripts, it is generally preferred to use a ligature or a half form to write a syllable or a cluster containing a dead consonant, although writing it with a visible virama is also possible. The Tamil script does not differentiate voiced and unvoiced plosives . Instead, plosives are articulated with voice depending on their position in a word, in accordance with the rules of Tamil phonology . In addition to

2288-622: Is a Dravidian language natively spoken by the Tamil people of South Asia . It is one of the two longest-surviving classical languages in India , along with Sanskrit , attested since c. 300 BCE. The language belongs to the southern branch of the Dravidian language family and shares close ties with Malayalam and Kannada . Despite external influences, Tamil has retained a sense of linguistic purism, especially in formal and literary contexts. Tamil

2392-457: Is based on the dialect of Jaffna . After Tamil Brahmi fell out of use, Tamil was written using a script called vaṭṭeḻuttu amongst others such as Grantha and Pallava . The current Tamil script consists of 12 vowels , 18 consonants and one special character, the āytam . The vowels and consonants combine to form 216 compound characters, giving a total of 247 characters (12 + 18 + 1 + (12 × 18)). All consonants have an inherent vowel

2496-434: Is commonly used to prepare clearcut sites for planting, e.g., in central British Columbia, and in the temperate region of North America generally. Prescribed burning is carried out primarily for slash hazard reduction and to improve site conditions for regeneration; all or some of the following benefits may accrue: Prescribed burning for preparing sites for direct seeding was tried on a few occasions in Ontario, but none of

2600-401: Is deemed unlikely by Southworth due to the contemporary use of the compound 'centamiḻ', which means refined speech in the earliest literature. The Tamil Lexicon of University of Madras defines the word "Tamil" as "sweetness". S. V. Subramanian suggests the meaning "sweet sound", from tam – "sweet" and il – "sound". Tamil belongs to the southern branch of the Dravidian languages ,

2704-563: Is extensively described in the oldest known grammar book for Tamil, the Tolkāppiyam . Modern Tamil writing is largely based on the 13th-century grammar Naṉṉūl which restated and clarified the rules of the Tolkāppiyam , with some modifications. Traditional Tamil grammar consists of five parts, namely eḻuttu , col , poruḷ , yāppu , aṇi . Of these, the last two are mostly applied in poetry. Tamil words consist of

2808-501: Is found in Tholkappiyam , which is dated as early as late 2nd century BCE. The Hathigumpha inscription , inscribed around a similar time period (150 BCE), by Kharavela , the Jain king of Kalinga , also refers to a Tamira Samghatta ( Tamil confederacy ) The Samavayanga Sutra dated to the 3rd century BCE contains a reference to a Tamil script named 'Damili'. Southworth suggests that

2912-405: Is generally taken to have been completed by the 8th century, was characterised by a number of phonological and grammatical changes. In phonological terms, the most important shifts were the virtual disappearance of the aytam (ஃ), an old phoneme, the coalescence of the alveolar and dental nasals, and the transformation of the alveolar plosive into a rhotic . In grammar, the most important change

3016-409: Is generally used in formal writing and speech. For instance, it is the language of textbooks, of much of Tamil literature and of public speaking and debate. In recent times, however, koṭuntamiḻ has been making inroads into areas that have traditionally been considered the province of centamiḻ . Most contemporary cinema, theatre and popular entertainment on television and radio, for example,

3120-410: Is in koṭuntamiḻ , and many politicians use it to bring themselves closer to their audience. The increasing use of koṭuntamiḻ in modern times has led to the emergence of unofficial 'standard' spoken dialects. In India, the 'standard' koṭuntamiḻ , rather than on any one dialect, but has been significantly influenced by the dialects of Thanjavur and Madurai . In Sri Lanka, the standard

3224-771: Is not always consistently applied. ISO 15919 is an international standard for the transliteration of Tamil and other Indic scripts into Latin characters. It uses diacritics to map the much larger set of Brahmic consonants and vowels to Latin script , and thus the alphabets of various languages, including English. Apart from the usual numerals, Tamil has numerals for 10, 100 and 1000. Symbols for day, month, year, debit, credit, as above, rupee, and numeral are present as well. Tamil also uses several historical fractional signs. /f/ , /z/ , /ʂ/ and /ɕ/ are only found in loanwords and may be considered marginal phonemes, though they are traditionally not seen as fully phonemic. Tamil has two diphthongs : /aɪ̯/ ஐ and /aʊ̯/ ஔ ,

3328-489: Is often referred to as conventional tillage , but as conservational tillage is now more widely used than intensive tillage (in the United States), it is often not appropriate to refer to this type of tillage as conventional. Intensive tillage often involves multiple operations with implements such as a mold board, disk, or chisel plow . After this, a finisher with a harrow , rolling basket, and cutter can be used to prepare

3432-475: Is predominantly spoken in Tamil Nadu , India, and the Northern and Eastern provinces of Sri Lanka . It has significant speaking populations in Malaysia , Singapore , and among diaspora communities . Tamil has been recognized as a classical language by the Indian government and holds official status in Tamil Nadu, Puducherry and Singapore. The earliest extant Tamil literary works and their commentaries celebrate

3536-459: Is situated at the centre of the island, around 11 kilometres from the township of Pamban and 18 kilometres from Dhanushkodi . Pamban, situated at the western edge of Pamban Island, is a fishing village and a harbour which is the main point of entry for the pilgrimage centre of Rameswaram. It has a population of around 9,000 inhabitants. Its importance has enhanced because it is located at the eastern end of Pamban Bridge through which supplies enter

3640-521: Is situated between 9°11' N and 9°19' N latitude and 79°12' E to 79°23' E longitudes. The chain formed by Pamban Island, the shoals of Adam's Bridge , and Mannar Island of Sri Lanka separate Palk Bay and the Palk Strait in the northeast from the Gulf of Mannar in the southwest. Pamban Island extends for around 30 km in width from the township of Pamban in the west to the remains of Dhanushkodi towards

3744-409: Is the Tolkāppiyam , an early work on Tamil grammar and poetics, whose oldest layers could be as old as the late 2nd century BCE. Many literary works in Old Tamil have also survived. These include a corpus of 2,381 poems collectively known as Sangam literature . These poems are usually dated to between the 1st century BCE and 5th century CE. The evolution of Old Tamil into Middle Tamil , which

3848-425: Is undertaken to ameliorate one or more constraints that would otherwise be likely to thwart management objectives. A valuable bibliography on the effects of soil temperature and site preparation on subalpine and boreal tree species has been prepared by McKinnon et al. (2002). Site preparation is the work that is done before a forest area is regenerated. Some types of site preparation are burning. Broadcast burning

3952-772: Is used as one of the languages of education in Malaysia , along with English, Malay and Mandarin. A large community of Pakistani Tamils speakers exists in Karachi , Pakistan , which includes Tamil-speaking Hindus as well as Christians and Muslims – including some Tamil-speaking Muslim refugees from Sri Lanka. There are about 100 Tamil Hindu families in Madrasi Para colony in Karachi. They speak impeccable Tamil along with Urdu, Punjabi and Sindhi. Many in Réunion , Guyana , Fiji , Suriname , and Trinidad and Tobago have Tamil origins, but only

4056-458: The Pandiyan Kings for the organization of long-termed Tamil Sangams , which researched, developed and made amendments in Tamil language. Even though the name of the language which was developed by these Tamil Sangams is mentioned as Tamil, the period when the name "Tamil" came to be applied to the language is unclear, as is the precise etymology of the name. The earliest attested use of the name

4160-584: The University of Madras , was one of the earliest dictionaries published in Indian languages. A strong strain of linguistic purism emerged in the early 20th century, culminating in the Pure Tamil Movement which called for removal of all Sanskritic elements from Tamil. It received some support from Dravidian parties . This led to the replacement of a significant number of Sanskrit loanwords by Tamil equivalents, though many others remain. According to

4264-725: The farm tractor was introduced, which made modern large-scale agriculture possible. However, the destruction of the prairie grasses and tillage of the fertile topsoil of the American Midwest caused the Dust Bowl , in which the soil was blown away and stirred up into dust storms that blackened the sky. This prompted re-consideration of tillage techniques, but in the United States as of 2019, 3 trillion pounds of soil were estimated to be lost due to erosion while adoption of improved techniques for controlling erosion are still not widespread.

4368-469: The forest fire hazard on harvested sites. Forest managers interested in the application of prescribed burning for hazard reduction and silviculture, were shown a method for quantifying the slash load by Kiil (1968). In west-central Alberta, he felled, measured, and weighed 60 white spruce, graphed (a) slash weight per merchantable unit volume against diameter at breast height (dbh), and (b) weight of fine slash (<1.27 cm) also against dbh, and produced

4472-486: The 11th century, retain many features of the Vaishnava paribasai , a special form of Tamil developed in the 9th and 10th centuries that reflect Vaishnavite religious and spiritual values. Several castes have their own sociolects which most members of that caste traditionally used regardless of where they come from. It is often possible to identify a person's caste by their speech. For example, Tamil Brahmins tend to speak

4576-546: The December 1964 cyclone destroyed the town in its entirety claiming over 2,000 lives and crippling power supply and communications. Houses, temples, churches, dispensaries and dharmashalas were destroyed leaving nothing but a ghost town. Some of the dharmashalas and a prominent mutt based in Dhanushkodi have been moved to Rameswaram. But Dhanushkodi could never be rebuilt. Dhanushkodi was well connected by rail and road with Pamban and

4680-476: The Indian state of Haryana , purportedly as a rebuff to Punjab , though there was no attested Tamil-speaking population in the state, and was later replaced by Punjabi , in 2010. In Malaysia, 543 primary education government schools are available fully in Tamil as the medium of instruction . The establishment of Tamil-medium schools has been in process in Myanmar to provide education completely in Tamil language by

4784-469: The Indian state of Tamil Nadu and one of the 22 languages under schedule 8 of the constitution of India . It is one of the official languages of the union territories of Puducherry and the Andaman and Nicobar Islands . Tamil is also one of the official languages of Singapore . Tamil is one of the official and national languages of Sri Lanka, along with Sinhala . It was once given nominal official status in

4888-585: The Tamil language, Kannada still preserves a lot from its roots. As part of the southern family of Indian languages and situated relatively close to the northern parts of India, Kannada also shares some Sanskrit words, similar to Malayalam. Many of the formerly used words in Tamil have been preserved with little change in Kannada. This shows a relative parallel to Tamil, even as Tamil has undergone some changes in modern ways of speaking. According to Hindu legend, Tamil or in personification form Tamil Thāi (Mother Tamil)

4992-673: The Tamils who settled there 200 years ago. Tamil language is available as a course in some local school boards and major universities in Canada and the month of January has been declared "Tamil Heritage Month" by the Parliament of Canada . Tamil enjoys a special status of protection under Article 6(b), Chapter 1 of the Constitution of South Africa and is taught as a subject in schools in KwaZulu-Natal province. Recently, it has been rolled out as

5096-560: The USA's Northern Corn Belt states lacks consistent yield results; however, there is still interest in deep tillage within agriculture. In areas that are not well-drained, deep tillage may be used as an alternative to installing more expensive tile drainage. Plowing: Tilling can damage ancient structures such as long barrows . In the UK, half of the long barrows in Gloucestershire and almost all

5200-442: The ancient language ( sankattamiḻ ), a modern literary and formal style ( centamiḻ ), and a modern colloquial form ( koṭuntamiḻ ). These styles shade into each other, forming a stylistic continuum. For example, it is possible to write centamiḻ with a vocabulary drawn from caṅkattamiḻ , or to use forms associated with one of the other variants while speaking koṭuntamiḻ . In modern times, centamiḻ

5304-463: The book "Horse-Hoeing Husbandry: An Essay on the Principles of Vegetation and Tillage," which argued that soil needed to be pulverized into fine powder for plants to make use of it. Tull believed that, since water, air, and heat were clearly not the primary substance of a plant, plants were made of earth, and thus had to consume very small pieces of earth as food. Tull wrote that each subsequent tillage of

5408-551: The burial mounds in Essex have been damaged. According to English Heritage in 2003, ploughing with modern powerful tractors had done as much damage in the last six decades as traditional farming did in the previous six centuries. Modern agricultural science has greatly reduced the use of tillage. Crops can be grown for several years without any tillage through the use of herbicides to control weeds, crop varieties that tolerate packed soil, and equipment that can plant seeds or fumigate

5512-490: The burned sites were probably the result of slight reductions in the depth of the organic layer, minor increases in soil temperature, and marked improvements in the efficiency of the planting crews. Results also suggested that the process of site deterioration has not been reversed by the burning treatments applied. Slash weight (the oven-dry weight of the entire crown and that portion of the stem less than four inches in diameter) and size distribution are major factors influencing

5616-478: The burns was hot enough to produce a seedbed that was adequate without supplementary mechanical site preparation. Changes in soil chemical properties associated with burning include significantly increased pH, which Macadam (1987) in the Sub-boreal Spruce Zone of central British Columbia found persisting more than a year after the burn. Average fuel consumption was 20 to 24 t/ha and the forest floor depth

5720-401: The control did not reach that temperature until 58 days after planting. During the first growing season, mounds had 3 times as many days with a mean soil temperature greater than 10 °C than did the control microsites. Draper et al.'s (1985) mounds received 5 times the amount of photosynthetically active radiation (PAR) summed over all sampled microsites throughout the first growing season;

5824-418: The control treatment consistently received about 14% of daily background PAR, while mounds received over 70%. By November, fall frosts had reduced shading, eliminating the differential. Quite apart from its effect on temperature, incident radiation is also important photosynthetically. The average control microsite was exposed to levels of light above the compensation point for only 3 hours, i.e., one-quarter of

5928-449: The crop plants. Primary tillage loosens the soil and mixes in fertilizer or plant material, resulting in soil with a rough texture. Secondary tillage produces finer soil and sometimes shapes the rows, preparing the seed bed. It also provides weed control throughout the growing season during the maturation of the crop plants, unless such weed control is instead achieved with low-till or no-till methods involving herbicides . Tilling

6032-499: The crop row. In comparison to no-till, which relies on the previous year's plant residue to protect the soil and aids in postponement of the warming of the soil and crop growth in Northern climates, zone tillage produces a strip approximately five inches wide that simultaneously breaks up plow pans, assists in warming the soil and helps to prepare a seedbed. When combined with cover crops, zone tillage helps replace lost organic matter, slows

6136-670: The culture associated with the Neolithic complexes of South India, but it has also been related to the Harappan civilization . Scholars categorise the attested history of the language into three periods: Old Tamil (300 BCE–700 CE), Middle Tamil (700–1600) and Modern Tamil (1600–present). About of the approximately 100,000 inscriptions found by the Archaeological Survey of India in India are in Tamil Nadu. Of them, most are in Tamil, with only about 5 percent in other languages. In 2004,

6240-454: The daily light period, whereas mounds received light above the compensation point for 11 hours, i.e., 86% of the same daily period. Assuming that incident light in the 100–600 μE/m /s intensity range is the most important for photosynthesis , the mounds received over 4 times the total daily light energy that reached the control microsites. With linear site preparation, orientation is sometimes dictated by topography or other considerations, but

6344-515: The deterioration of the soil, improves soil drainage, increases soil water and nutrient holding capacity, and allows necessary soil organisms to survive. It has been successfully used on farms in the Midwest and West of the USA for over 40 years, and is currently used on more than 36% of the U.S. farmland. Some specific states where zone tillage is currently in practice are Pennsylvania, Connecticut, Minnesota, Indiana, Wisconsin, and Illinois. Its use in

Although Tamil dialects do not differ significantly in their vocabulary, there are a few exceptions. The dialects spoken in Sri Lanka retain many words and grammatical forms that are not in everyday use in India, and use many other words slightly differently. Tamil dialects include Central Tamil dialect , Kongu Tamil , Madras Bashai , Madurai Tamil , Nellai Tamil , Kumari Tamil in India ; Batticaloa Tamil dialect , Jaffna Tamil dialect , Negombo Tamil dialect in Sri Lanka; and Malaysian Tamil in Malaysia. Sankethi dialect in Karnataka has been heavily influenced by Kannada . The dialect of

Similarly, Tamil spoken in Kanyakumari District has more unique words and phonetic style than Tamil spoken at other parts of Tamil Nadu. The words and phonetics are so different that a person from Kanyakumari district is easily identifiable by their spoken Tamil.

However, in another study in the same Sub-boreal Spruce Zone found that although it increased immediately after the burn, phosphorus availability had dropped to below pre-burn levels within 9 months. Nitrogen will be lost from the site by burning, though concentrations in remaining forest floor were found by Macadam (1987) to have increased in two out of six plots,

6864-577: The high Rocky Mountains is emphasized by the U.S. Forest Service. Acceptable planting spots are defined as microsites on the north and east sides of down logs, stumps, or slash, and lying in the shadow cast by such material. Where the objectives of management specify more uniform spacing, or higher densities, than obtainable from an existing distribution of shade-providing material, redistribution or importing of such material has been undertaken. Site preparation on some sites might be done simply to facilitate access by planters, or to improve access and increase

6968-699: The hill country . Tamil or dialects of it were used widely in the state of Kerala as the major language of administration, literature and common usage until the 12th century CE. Tamil was also used widely in inscriptions found in southern Andhra Pradesh districts of Chittoor and Nellore until the 12th century CE. Tamil was used for inscriptions from the 10th through 14th centuries in southern Karnataka districts such as Kolar , Mysore , Mandya and Bengaluru . There are currently sizeable Tamil-speaking populations descended from colonial-era migrants in Malaysia , Singapore , Philippines , Mauritius , South Africa , Indonesia, Thailand, Burma , and Vietnam .

Rameswaram with a population of 44,856 (2011 census) is the largest and most populous town on the island. It is one of the most sacred Hindu religious sites and a pilgrimage destination for thousands of Hindus every year. The Ramanathaswamy Temple at Rameswaram has the longest corridor in Asia. Rameswaram

7384-412: The island. Pamban is 11 kilometres from Rameswaram, 30 kilometres from the tip of Dhanushkodi and around 7 kilometres from Mandapam on the Indian mainland. It is separated from the Indian mainland by a narrow strip of sea. Thangachimadam , situated between Pamban and Rameswaram, is a minor settlement. It derives its name from a mutt (Madam) which is located in the town. There are a couple of temples and

7488-456: The latter of which is restricted to a few lexical items. Tamil employs agglutinative grammar, where suffixes are used to mark noun class , number , and case , verb tense and other grammatical categories. Tamil's standard metalinguistic terminology and scholarly vocabulary is itself Tamil, as opposed to the Sanskrit that is standard for most Indo-Aryan languages . Much of Tamil grammar

7592-417: The mainland until the cyclone struck. The ruins of the station and the railway track have been left untouched thereby making the ghost-town a popular tourist destination. Pamban Island has a few hillocks and elevated physical features in the vicinity of Rameswaram of which Mt. Gandamadana is the tallest. It is believed that this was the hillock from whose summit Lord Rama observed Sri Lanka and conceived

7696-456: The mid 1930s Frank and Herbert Petty of Doncaster, Victoria, Australia developed the Petty Plough . This steerable plough could be pulled by either two horses or a tractor and the disc wheels could be steered in unison, or separately allowing the operator to plough the center of rows as well as between and around orchard trees. Primary tillage is usually conducted after the last harvest, when

7800-652: The mortality of white spruce. Significant difference in height was found between open and sheltered plantations for black spruce but not for white spruce, and root collar diameter in sheltered plantations was significantly larger than in open plantations for black spruce but not for white spruce. Black spruce open plantation had significantly smaller volume (97 cm ) compared with black spruce sheltered (210 cm ), as well as white spruce open (175 cm ) and sheltered (229 cm ) plantations. White spruce open plantations also had smaller volume than white spruce sheltered plantations. For transplant stock, strip plantations had

7904-423: The name comes from tam-miḻ > tam-iḻ "self-speak", or "our own speech". Kamil Zvelebil suggests an etymology of tam-iḻ , with tam meaning "self" or "one's self", and " -iḻ " having the connotation of "unfolding sound". Alternatively, he suggests a derivation of tamiḻ < tam-iḻ < * tav-iḻ < * tak-iḻ , meaning in origin "the proper process (of speaking)". However, this

8008-532: The number of times the farmer travels over the field, significant savings in fuel and labor are made. Conservation tillage is used on over 370 million acres, mostly in South America, Oceania and North America. In most years since 1997, conservation tillage was used in US cropland more than intensive or reduced tillage. However, conservation tillage delays warming of the soil due to the reduction of dark earth exposure to

8112-447: The number or distribution of microsites suitable for planting or seeding. Wang et al. (2000) determined field performance of white and black spruces 8 and 9 years after outplanting on boreal mixedwood sites following site preparation (Donaren disc trenching versus no trenching) in 2 plantation types (open versus sheltered) in southeastern Manitoba. Donaren trenching slightly reduced the mortality of black spruce but significantly increased

8216-531: The old aspect and time markers. The Nannūl remains the standard normative grammar for modern literary Tamil, which therefore continues to be based on Middle Tamil of the 13th century rather than on Modern Tamil. Colloquial spoken Tamil, in contrast, shows a number of changes. The negative conjugation of verbs, for example, has fallen out of use in Modern Tamil – instead, negation is expressed either morphologically or syntactically. Modern spoken Tamil also shows

8320-586: The orientation can often be chosen. It can make a difference. A disk-trenching experiment in the Sub-boreal Spruce Zone in interior British Columbia investigated the effect on growth of young outplants ( lodgepole pine ) in 13 microsite planting positions: berm, hinge, and trench in each of north, south, east, and west aspects, as well as in untreated locations between the furrows. Tenth-year stem volumes of trees on south-, east-, and west-facing microsites were significantly greater than those of trees on north-facing and untreated microsites. However, planting spot selection

8424-491: The others showing decreases. Nutrient losses may be outweighed, at least in the short term, by improved soil microclimate through the reduced thickness of forest floor where low soil temperatures are a limiting factor. The Picea/Abies forests of the Alberta foothills are often characterized by deep accumulations of organic matter on the soil surface and cold soil temperatures, both of which make reforestation difficult and result in

8528-598: The policy of seeking and obtaining for field testing new equipment from Scandinavia and elsewhere that seemed to hold promise for Ontario conditions, primarily in the north. Thus, testing was begun of the Brackekultivator from Sweden and the Vako-Visko rotary furrower from Finland. Site preparation treatments that create raised planting spots have commonly improved outplant performance on sites subject to low soil temperature and excess soil moisture. Mounding can certainly have

8632-494: The seasons be temperate in moisture and dryness   ... you must labor it most exquisitely, harrow it and manure it very oft with great store of dung, so you shall make it better   ... but especially desire that they may not be watered with rain, for water is as good as poison to them. The popularity of tillage as an agricultural technique in early modern times had to do with theories about plant biology proposed by European thinkers. In 1731, English writer Jethro Tull published

8736-538: The seed bed. There are many variations. Conservation tillage leaves at least 30% of crop residue on the soil surface, or at least 1,000 lb/ac (1,100 kg/ha) of small grain residue on the surface during the critical soil erosion period. This slows water movement, which reduces the amount of soil erosion. Additionally, conservation tillage has been found to benefit predatory arthropods that can enhance pest control. Conservation tillage also benefits farmers by reducing fuel consumption and soil compaction. By reducing

8840-473: The slash. The S.F.I. scarifier, after strengthening, had been "quite successful" for 2 years, promising trials were under way with the cone scarifier and barrel ring scarifier, and development had begun on a new flail scarifier for use on sites with shallow, rocky soils. Recognition of the need to become more effective and efficient in site preparation led the Ontario Department of Lands and Forests to adopt

8944-461: The soil is wet enough to allow plowing but also allows good traction. Some soil types can be plowed dry. The objective of primary tillage is to attain a reasonable depth of soft soil, incorporate crop residues, kill weeds, and to aerate the soil. Secondary tillage is any subsequent tillage, to incorporate fertilizers, reduce the soil to a finer tilth , level the surface, or control weeds. Reduced tillage leaves between 15 and 30% crop residue cover on

9048-445: The soil or 500 to 1000 pounds per acre (560 to 1100 kg/ha) of small grain residue during the critical erosion period. This may involve the use of a chisel plow, field cultivators, or other implements. See the general comments below to see how they can affect the amount of residue. Intensive tillage leaves less than 15% crop residue cover or less than 500 pounds per acre (560 kg/ha) of small grain residue. This type of tillage

9152-581: The soil without really digging it up. This practice, called no-till farming , reduces costs and environmental change by reducing soil erosion and diesel fuel usage. Site preparation is any of the various treatments applied to a site to ready it for seeding or planting. The purpose is to facilitate the regeneration of that site by the chosen method. Site preparation may be designed to achieve, singly or in any combination, improved access by reducing or rearranging slash and ameliorating adverse forest floor, soil, vegetation, or other biotic factors. Site preparation

9256-540: The soil would increase its fertility, and that it was impossible to till the soil too much. However, scientific observation has shown that the opposite is true; tillage causes soil to lose structural qualities that allow plant roots, water, and nutrients to penetrate it, accelerates soil loss by erosion , and results in soil compaction . The steel plow allowed farming in the American Midwest , where tough prairie grasses and rocks caused trouble. Soon after 1900,

9360-482: The south-east. The length of the island varies from 2 km at the Dhanushkodi promontory to 7 km near Rameswaram. The area of the island is around 67 km. Pamban Island constitutes a separate taluk of Ramanathapuram district with four administrative divisions, Okarisalkulam, Mahindi, Pamban and Rameswaram. There are two administrative villages, Pamban and Rameswaram. The two main towns on Pamban Island are Pamban and Rameswaram . There are also smaller settlements upon

9464-465: The standard characters, six characters taken from the Grantha script , which was used in the Tamil region to write Sanskrit, are sometimes used to represent sounds not native to Tamil, that is, words adopted from Sanskrit, Prakrit , and other languages. The traditional system prescribed by classical grammars for writing loan-words, which involves respelling them in accordance with Tamil phonology, remains, but

9568-432: The state of site preparation in Ontario noted that blades and rakes were found to be well suited to post-cut scarification in tolerant hardwood stands for natural regeneration of yellow birch . Plows were most effective for treating dense brush prior to planting, often in conjunction with a planting machine. Scarifying teeth, e.g., Young's teeth, were sometimes used to prepare sites for planting, but their most effective use

9672-426: The warmth of the spring sun, thus delaying the planting of the next year's spring crop of corn. Zone tillage is a form of modified deep tillage in which only narrow strips are tilled, leaving soil in between the rows untilled. This type of tillage agitates the soil to help reduce soil compaction problems and to improve internal soil drainage . It is designed to only disrupt the soil in a narrow strip directly below

9776-517: The word for "here"— iṅku in Centamil (the classic variety)—has evolved into iṅkū in the Kongu dialect of Coimbatore , inga in the dialects of Thanjavur and Palakkad , and iṅkai in some dialects of Sri Lanka . Old Tamil's iṅkaṇ (where kaṇ means place) is the source of iṅkane in the dialect of Tirunelveli , Old Tamil iṅkiṭṭu is the source of iṅkuṭṭu in

9880-526: Was a Tamilian himself, in a joint sitting of both houses of the Indian Parliament on 6 June 2004. The socio-linguistic situation of Tamil is characterised by diglossia : there are two separate registers varying by socioeconomic status , a high register and a low one. Tamil dialects are primarily differentiated from each other by the fact that they have undergone different phonological changes and sound shifts in evolving from Old Tamil. For example,

9984-586: Was claimed to be dated to around 580 BCE. John Guy states that Tamil was the lingua franca for early maritime traders from India. Tamil language inscriptions written in Brahmi script have been discovered in Sri Lanka and on trade goods in Thailand and Egypt. In November 2007, an excavation at Quseir-al-Qadim revealed Egyptian pottery dating back to first century BCE with ancient Tamil Brahmi inscriptions. There are

10088-528: Was created by Lord Shiva . Murugan , revered as the Tamil God, along with sage Agastya , brought it to the people. Tamil, like other Dravidian languages, ultimately descends from the Proto-Dravidian language , which was most likely spoken around the third millennium BCE, possibly in the region around the lower Godavari river basin. The material evidence suggests that the speakers of Proto-Dravidian were of

10192-587: Was first performed via human labor, sometimes involving slaves . Hoofed animals could also be used to till soil by trampling, in addition to pigs, whose natural instincts are to root the ground regularly if allowed to. The wooden plow was then invented. ( It is difficult to pinpoint the exact date of its invention . However, the earliest evidence of plow usage dates back to around 4000 BCE in Mesopotamia ( modern-day Iraq ) . It could be pulled with human labor, or by mule , ox , elephant , water buffalo , or

10296-434: Was found to be preparing sites for seeding, particularly in backlog areas carrying light brush and dense herbaceous growth. Rolling choppers found application in treating heavy brush but could be used only on stone-free soils. Finned drums were commonly used on jack pine–spruce cutovers on fresh brushy sites with a deep duff layer and heavy slash, and they needed to be teamed with a tractor pad unit to secure good distribution of

10400-621: Was increasing. According to J. Hall (1970), in Ontario at least, the most widely used site preparation technique was post-harvest mechanical scarification by equipment front-mounted on a bulldozer (blade, rake, V-plow, or teeth), or dragged behind a tractor (Imsett or S.F.I. scarifier, or rolling chopper). Drag type units designed and constructed by Ontario's Department of Lands and Forests used anchor chain or tractor pads separately or in combination, or were finned steel drums or barrels of various sizes and used in sets alone or combined with tractor pad or anchor chain units. J. Hall's (1970) report on

10504-431: Was reduced by 28% to 36%. The increases correlated well with the amounts of slash (both total and ≥7 cm diameter) consumed. The change in pH depends on the severity of the burn and the amount consumed; the increase can be as much as 2 units, a 100-fold change. Deficiencies of copper and iron in the foliage of white spruce on burned clearcuts in central British Columbia might be attributable to elevated pH levels. Even

10608-471: Was seen to be more important overall than trench orientation. In a Minnesota study, the N–S strips accumulated more snow but snow melted faster than on E–W strips in the first year after felling. Snow-melt was faster on strips near the centre of the strip-felled area than on border strips adjoining the intact stand. The strips, 50 feet (15.24 m) wide, alternating with uncut strips 16 feet (4.88 m) wide, were felled in

10712-504: Was the lingua franca for early maritime traders, with inscriptions found in places like Sri Lanka , Thailand , and Egypt . The language has a well-documented history with literary works like Sangam literature , consisting of over 2,000 poems. Tamil script evolved from Tamil Brahmi, and later, the vatteluttu script was used until the current script was standardized. The language has a distinct grammatical structure, with agglutinative morphology that allows for complex word formations. Tamil

10816-451: Was the emergence of the present tense. The present tense evolved out of the verb kil ( கில் ), meaning "to be possible" or "to befall". In Old Tamil, this verb was used as an aspect marker to indicate that an action was micro-durative, non-sustained or non-lasting, usually in combination with a time marker such as ṉ ( ன் ). In Middle Tamil, this usage evolved into a present tense marker – kiṉṟa ( கின்ற ) – which combined
