83-754: Most commercial agriculture is intensive in one or more ways. Forms that rely heavily on industrial methods are often called industrial agriculture , which is characterized by technologies designed to increase yield. Techniques include planting multiple crops per year, reducing the frequency of fallow years, improving cultivars , mechanised agriculture , controlled by increased and more detailed analysis of growing conditions, including weather, soil , water, weeds, and pests. Modern methods frequently involve increased use of non-biotic inputs, such as fertilizers , plant growth regulators, pesticides , and antibiotics for livestock. Intensive farms are widespread in developed nations and increasingly prevalent worldwide. Most of

166-455: A phytohormone involved in regulating stem growth via its effect on cell division. Photosynthate investment in the stem is reduced dramatically in shorter plants and nutrients become redirected to grain production, amplifying in particular the yield effect of chemical fertilizers. High-yielding varieties outperformed traditional varieties several fold and responded better to the addition of irrigation, pesticides, and fertilizers. Hybrid vigour

249-527: A runaway reaction , with the decomposition process becoming explosive. See § Disasters for details. Many ammonium nitrate disasters , with loss of lives, have occurred. The red–orange colour in an explosion cloud is due to nitrogen dioxide , a secondary reaction product. A number of crystalline phases of ammonium nitrate have been observed. The following occur under atmospheric pressure. The transition between β-rhombic to α-rhombic forms (at 32.3 °C) occurs at ambient temperature in many parts of

332-407: A terrace is a leveled section of a hilly cultivated area, designed as a method of soil conservation to slow or prevent the rapid surface runoff of irrigation water. Often such land is formed into multiple terraces, giving a stepped appearance. The human landscapes of rice cultivation in terraces that follow the natural contours of the escarpments, like contour ploughing , are a classic feature of

415-400: A confined space. The resulting heat and pressure from decomposition increases the sensitivity to detonation and increases the speed of decomposition. Detonation may occur at 80 atmospheres . Contamination can reduce this to 20 atmospheres. Ammonium nitrate has a critical relative humidity of 59.4% at 30 °C. At higher humidity it will absorb moisture from the atmosphere. Therefore, it

498-508: A country and the rest of the world is called foreign or international trade , which consists of import trade and export trade, both being wholesale in general. Commerce not only includes trade as defined above, but also the auxiliary services or aids to trade and means that facilitate such trade. Auxiliary services aid trade by providing services which such as transportation , communication , warehousing , insurance , banking , credit financing to companies, advertising , packaging , and

581-699: A country. International commerce can be regulated by bilateral treaties between countries. After the second world war and the rise of free trade among nations, multilateral arrangements such as the GATT and later the World Trade Organization became the principal systems regulating global commerce. The International Chamber of Commerce (ICC) is another important organization which sets rules and resolves disputes in international commerce. Where national government bodies undertake commercial activity with or inside other states, this commercial activity may fall outside

664-472: A crust on the ground or in conjunction with other nitrate, iodate , and halide minerals . Ammonium nitrate was mined there until the Haber–Bosch process made it possible to synthesize nitrates from atmospheric nitrogen, thus rendering nitrate mining obsolete. The industrial production of ammonium nitrate entails the acid-base reaction of ammonia with nitric acid : The ammonia required for this process

747-498: A general sense, business is the activity of earning money and making one's living through engaging in commerce. However, in a more specific sense, a business is an organization or activity for making a profit by providing goods and services which meet the needs of its customers or consumers. Business organizations typically operate in the primary (dealing with the extraction and sourcing of raw materials) and secondary (dealing with manufacturing intermediate or finished goods) sectors of

830-605: A much more equal and controlled distribution pattern. Drip irrigation is the most expensive and least-used type, but delivers water to plant roots with minimal losses. Water catchment management measures include recharge pits, which capture rainwater and runoff and use it to recharge groundwater supplies. This helps in the replenishment of groundwater wells and eventually reduces soil erosion. Dammed rivers creating reservoirs store water for irrigation and other uses over large areas. Smaller areas sometimes use irrigation ponds or groundwater. In agriculture, systematic weed management

913-472: A paddock, while allowing the others to recover. Resting grazed lands allows the vegetation to renew energy reserves, rebuild shoot systems, and deepen root systems, resulting in long-term maximum biomass production. Pasture systems alone can allow grazers to meet their energy requirements, but rotational grazing is especially effective because grazers thrive on the more tender younger plant stems. Parasites are also left behind to die off, minimizing or eliminating

996-520: A regional or national scale, and the functioning of agro-ecosystems has been profoundly altered. Agricultural intensification includes a variety of factors, including the loss of landscape elements, increased farm and field sizes, and increase usage of insecticides and herbicides. The large scale of insecticides and herbicides lead to the rapid developing resistance among pests renders herbicides and insecticides increasingly ineffective. Agrochemicals have may be involved in colony collapse disorder , in which

1079-479: A relatively small area of land, for example by rotational grazing , or sometimes as concentrated animal feeding operations . These methods increase the yields of food and fiber per unit land area compared to those of extensive animal husbandry ; concentrated feed is brought to seldom-moved animals, or, with rotational grazing, the animals are repeatedly moved to fresh forage. Agricultural development in Britain between

1162-461: A small space poses ethical issues to some consumers. Animal rights and animal welfare activists have charged that intensive animal rearing is cruel to animals. The Green Revolution transformed farming in many developing countries. It spread technologies that had already existed, but had not been widely used outside of industrialized nations. These technologies included "miracle seeds", pesticides, irrigation, and synthetic nitrogen fertilizer. In

1245-699: A strong initiation charge. It should not be stored near high explosives or blasting agents. Molten ammonium nitrate is very sensitive to shock and detonation, particularly if it becomes contaminated with incompatible materials such as combustibles, flammable liquids, acids, chlorates, chlorides, sulfur, metals, charcoal and sawdust. Contact with certain substances such as chlorates , mineral acids and metal sulfides , can lead to vigorous or even violent decomposition capable of igniting nearby combustible material or detonating. Ammonium nitrate begins decomposition after melting, releasing NO x , HNO 3 , NH 3 and H 2 O . It should not be heated in

1328-681: A wider variety of goods and services, and encourages innovation and competition for better products . On the other hand, commerce can worsen economic inequality by concentrating wealth (and power ) into the hands of a small number of individuals , and by prioritizing short-term profit over long-term sustainability and ethical , social , and environmental considerations, leading to environmental degradation , labor exploitation and disregard for consumer safety . Unregulated, it can lead to excessive consumption (generating undesirable waste ) and unsustainable exploitation of nature (causing resource depletion ). Harnessing commerce's benefits for

1411-454: Is a salt , both the cation, NH + 4 , and the anion, NO − 3 , may take part in chemical reactions. Solid ammonium nitrate decomposes on heating. At temperatures below around 300 °C, the decomposition mainly produces nitrous oxide and water: At higher temperatures, the following reaction predominates. Both decomposition reactions are exothermic and their products are gas. Under certain conditions, this can lead to

1494-533: Is a mixture of 94% ammonium nitrate ("AN") and 6% fuel oil ("FO") widely used as a bulk industrial explosive . It is used in coal mining , quarrying , metal mining , and civil construction in undemanding applications where the advantages of ANFO's low cost, relative safety, and ease of use matter more than the benefits offered by conventional industrial explosives, such as water resistance, oxygen balance , high detonation velocity, and performance in small diameters. Ammonium nitrate-based explosives were used in

1577-481: Is a part of commerce and commerce is an aspect of business. Historian Peter Watson and Ramesh Manickam date the history of long-distance commerce from circa 150,000 years ago. In historic times, the introduction of currency as a standardized money facilitated the exchange of goods and services. Commerce was a costly endeavor in the antiquities because of the risky nature of transportation, which restricted it to local markets. Commerce then expanded along with

1660-531: Is a progressive, sustainable agriculture system such as zero waste agriculture or integrated multi-trophic aquaculture , which involves the interactions of multiple species. Elements of this integration can include: Industrial agriculture uses huge amounts of water , energy , and industrial chemicals , increasing pollution in the arable land , usable water , and atmosphere . Herbicides , insecticides , and fertilizers accumulate in ground and surface waters . Industrial agricultural practices are one of

1743-529: Is an important fertilizer with NPK rating 34-0-0 (34% nitrogen). It is less concentrated than urea (46-0-0), giving ammonium nitrate a slight transportation disadvantage. Ammonium nitrate's advantage over urea is that it is more stable and does not rapidly lose nitrogen to the atmosphere. Ammonium nitrate readily forms explosive mixtures with varying properties when combined with explosives such as TNT or with fuels like aluminum powder or fuel oil. Examples of explosives containing ammonium nitrate include: ANFO

1826-432: Is continuously cropped. Crop rotation also seeks to balance the nutrient demands of various crops to avoid soil nutrient depletion. A traditional component of crop rotation is the replenishment of nitrogen through the use of legumes and green manure in sequence with cereals and other crops. Crop rotation can also improve soil structure and fertility by alternating deep-rooted and shallow-rooted plants. A related technique

1909-736: Is highly soluble in water and hygroscopic as a solid, although it does not form hydrates . It is predominantly used in agriculture as a high-nitrogen fertilizer . Its other major use is as a component of explosive mixtures used in mining, quarrying, and civil construction. It is the major constituent of ANFO , a popular industrial explosive which accounts for 80% of explosives used in North America; similar formulations have been used in improvised explosive devices . Many countries are phasing out its use in consumer applications due to concerns over its potential for misuse. Accidental ammonium nitrate explosions have killed thousands of people since

1992-628: Is hostile to many species of weeds . As the only draft animal species which is comfortable in wetlands , the water buffalo is in widespread use in Asian rice paddies. A recent development in the intensive production of rice is the System of Rice Intensification . Developed in 1983 by the French Jesuit Father Henri de Laulanié in Madagascar , by 2013 the number of smallholder farmers using

2075-959: Is important to store ammonium nitrate in a tightly sealed container. Otherwise, it can coalesce into a large, solid mass. Ammonium nitrate can absorb enough moisture to liquefy. Blending ammonium nitrate with certain other fertilizers can lower the critical relative humidity. The potential for use of the material as an explosive has prompted regulatory measures. For example, in Australia, the Dangerous Goods Regulations came into effect in August 2005 to enforce licensing in dealing with such substances. Licenses are granted only to applicants (industry) with appropriate security measures in place to prevent any misuse. Additional uses such as education and research purposes may also be considered, but individual use will not. Employees of those with licenses to deal with

2158-437: Is not concerned with the extraction of raw materials and the manufacturing of goods. Viewed in this way, commerce is a broader concept and an overall, all-encompassing aspect of business. Commerce provides the underlying large-scale transactional environment comprising all kinds of exchanges within which individual business organizations operate for generating profits. Commerce is distinguishable from trade as well. Trade

2241-669: Is obtained by the Haber process from nitrogen and hydrogen. Ammonia produced by the Haber process can be oxidized to nitric acid by the Ostwald process . Ammonia is used in its anhydrous form (a gas) and the nitric acid is concentrated. The reaction is violent owing to its highly exothermic nature. After the solution is formed, typically at about 83% concentration, the excess water is evaporated off to leave an ammonium nitrate (AN) content of 95% to 99.9% concentration (AN melt), depending on grade. The AN melt

2324-441: Is often increased, yields of any single crop often decrease. There are also challenges to farmers who rely on farming equipment optimized for monoculture , often resulting in increased labor inputs. Vertical farming is intensive crop production on a large scale in urban centers, in multi-story, artificially-lit structures, for the production of low-calorie foods like herbs, microgreens , and lettuce. An integrated farming system

2407-554: Is the concentration of livestock in a given space. The aim is to provide maximum output at the lowest possible cost and with the greatest level of food safety. The term is often used pejoratively. CAFOs have dramatically increased the production of food from animal husbandry worldwide, both in terms of total food produced and efficiency. Food and water is delivered to the animals, and therapeutic use of antimicrobial agents, vitamin supplements, and growth hormones are often employed. Growth hormones are not used on chickens nor on any animal in

2490-763: Is the improvement of pasture soils and grasses to increase the food production potential of livestock systems. It is commonly used to reverse pasture degradation , a process characterized by loss of forage and decreased animal carrying capacity which results from overgrazing , poor nutrient management , and lack of soil conservation . This degradation leads to poor pasture soils with decreased fertility and water availability and increased rates of erosion, compaction, and acidification . Degraded pastures have significantly lower productivity and higher carbon footprints compared to intensified pastures. Management practices which improve soil health and consequently grass productivity include irrigation , soil scarification, and

2573-408: Is the modern method to minimize pesticide use to more sustainable levels. There are concerns over the sustainability of industrial agriculture, and the environmental effects of fertilizers and pesticides, which has given rise to the organic movement and has built a market for sustainable intensive farming, as well as funding for the development of appropriate technology . Pasture intensification

2656-412: Is the transaction (buying and selling) of goods and services that makes a profit for the seller and satisfies the want or need of the buyer. When trade is carried out within a country, it is called home or domestic trade , which can be wholesale or retail . A wholesaler buys from the producer in bulk and sells to the retailer who then sells again to the final consumer in smaller quantities. Trade between

2739-570: Is then made into "prills" or small beads in a spray tower , or into granules by spraying and tumbling in a rotating drum. The prills or granules may be further dried, cooled, and then coated to prevent caking. These prills or granules are the typical AN products in commerce. Another production method is a variant of the nitrophosphate process : The products, calcium carbonate and ammonium nitrate, may be separately purified or sold combined as calcium ammonium nitrate . Ammonium nitrate can also be made via metathesis reactions : As ammonium nitrate

2822-492: Is to plant multi-species cover crops between commercial crops. This combines the advantages of intensive farming with continuous cover and polyculture . Crop irrigation accounts for 70% of the world's fresh water use. Flood irrigation , the oldest and most common type, is typically unevenly distributed, as parts of a field may receive excess water in order to deliver sufficient quantities to other parts. Overhead irrigation , using center-pivot or lateral-moving sprinklers, gives

2905-495: Is used in some instant cold packs , as its dissolution in water is highly endothermic . In 2021, King Abdullah University of Science and Technology in Saudi Arabia conducted experiments to study the potential for dissolving ammonium nitrate in water for off-grid cooling systems and as a refrigerant. They suggested that the water could be distilled and reused using solar energy to avoid water wastage in severe environments. It

2988-426: Is usually required, often performed by machines such as cultivators or liquid herbicide sprayers. Herbicides kill specific targets while leaving the crop relatively unharmed. Some of these act by interfering with the growth of the weed and are often based on plant hormones . Weed control through herbicide is made more difficult when the weeds become resistant to the herbicide. Solutions include: In agriculture ,

3071-527: Is utilized in many important crops to greatly increase yields for farmers. However, the advantage is lost for the progeny of the F1 hybrids , meaning seeds for annual crops need to be purchased every season, thus increasing costs and profits for farmers. Crop rotation or crop sequencing is the practice of growing a series of dissimilar types of crops in the same space in sequential seasons for benefits such as avoiding pathogen and pest buildup that occurs when one species

3154-527: The European Union ) or coalitions (like BRICS ) leading to its reconfiguration. The English-language word commerce has been derived from the Latin word commercium , from com ("together") and merx ("merchandise"). Despite many similarities (to the extent that they are sometimes used as synonyms in layman's terms and in other contexts), commerce, business and trade are distinct concepts. In

3237-427: The European Union . Undesirable behaviors often related to the stress of confinement led to a search for docile breeds (e.g., with natural dominant behaviors bred out), physical restraints to stop interaction, such as individual cages for chickens, or physical modification such as the debeaking of chickens to reduce the harm of fighting. The CAFO designation resulted from the 1972 U.S. Federal Clean Water Act , which

3320-469: The Industrial Revolution fundamentally reshaped commerce. In the post-colonial 20th century, free market principles gained ground, multinational corporations and consumer economies thrived in U.S.-led capitalist countries and free trade agreements (like GATT and WTO ) emerged, whereas communist economies encountered trade restrictions , limiting consumer choice . Furthermore, in

3486-979: The carbon balance is the use of integrated crop-livestock (ICL) and crop-livestock-forestry (ICLF) systems, which combine several ecosystems into one optimized agricultural framework. Correctly performed, such production systems are able to create synergies potentially providing benefits to pastures through optimal plant usage, improved feed and fattening rates, increased soil fertility and quality, intensified nutrient cycling , integrated pest control , and improved biodiversity . The introduction of certain legume crops to pastures can increase carbon accumulation and nitrogen fixation in soils, while their digestibility helps animal fattening and reduces methane emissions from enteric fermentation . ICLF systems yield beef cattle productivity up to ten times that of degraded pastures; additional crop production from maize , sorghum , and soybean harvests; and greatly reduced greenhouse gas balances due to forest carbon sequestration. In

Large stockpiles of the material can also be a major fire risk due to their supporting oxidation , a situation which can easily escalate to detonation. Explosions are not uncommon: relatively minor incidents occur most years, and several large and devastating explosions have also occurred. Examples include

3652-404: The safety data sheets available from suppliers and from various governments. Pure ammonium nitrate does not burn, but as a strong oxidizer, it supports and accelerates the combustion of organic (and some inorganic) material. It should not be stored near combustible substances. While ammonium nitrate is stable at ambient temperature and pressure under many conditions, it may detonate from

3735-576: The waste disposal issue and requires that animal waste be stored in lagoons . These lagoons can be as large as 7.5 acres (30,000 m). Lagoons not protected with an impermeable liner can leak into groundwater under some conditions, as can runoff from manure used as fertilizer. A lagoon that burst in 1995 released 25 million gallons of nitrous sludge in North Carolina's New River . The spill allegedly killed eight to ten million fish. The large concentration of animals, animal waste, and dead animals in

3818-426: The 15th to the early 20th century, European colonial powers dominated global commerce on an unprecedented scale, giving rise to maritime trade empires with their powerful colonial trade companies (e.g., Dutch East India Company and British East India Company ) and ushering in an unprecedented global exchange (see Columbian exchange ). In the 19th century, modern banking and related international markets along with

3901-449: The 16th century and the mid-19th century saw a massive increase in agricultural productivity and net output. This in turn contributed to unprecedented population growth, freeing up a significant percentage of the workforce, and thereby helped enable the Industrial Revolution . Historians cited enclosure , mechanization , four-field crop rotation , and selective breeding as the most important innovations. Industrial agriculture arose in

3984-403: The 1970s, scientists created high-yielding varieties of maize, wheat , and rice. These have an increased nitrogen-absorbing potential compared to other varieties. Since cereals that absorbed extra nitrogen would typically lodge (fall over) before harvest, semi-dwarfing genes were bred into their genomes. Norin 10 wheat , a variety developed by Orville Vogel from Japanese dwarf wheat varieties,

4067-571: The Industrial Revolution. By the early 19th century, agricultural techniques, implements, seed stocks, and cultivars had so improved that yield per land unit was many times that seen in the Middle Ages . The first phase involved a continuing process of mechanization. Horse-drawn machinery such as the McCormick reaper revolutionized harvesting, while inventions such as the cotton gin reduced

They can occur naturally along rivers or marshes , or can be constructed, even on hillsides. They require large water quantities for irrigation, much of it from flooding. It gives an environment favourable to the strain of rice being grown, and

4233-620: The Twelve Aprils grazing program for dairy production, developed by the USDA - SARE , forage crops for dairy herds are planted into a perennial pasture. Rotational grazing is a variety of foraging in which herds or flocks are regularly and systematically moved to fresh, rested grazing areas (sometimes called paddocks ) to maximize the quality and quantity of forage growth. It can be used with cattle, sheep, goats, pigs, chickens, turkeys, ducks, and other animals. The herds graze one portion of pasture, or

4316-578: The application of lime , fertilizers, and pesticides . Depending on the productivity goals of the target agricultural system, more involved restoration projects can be undertaken to replace invasive and under-productive grasses with grass species that are better suited to the soil and climate conditions of the region. These intensified grass systems allow higher stocking rates with faster animal weight gain and reduced time to slaughter, resulting in more productive, carbon-efficient livestock systems. Another technique to optimize yield while maintaining

4399-425: The association with intensive agricultural farming practices. For example the infectious salmon anaemia (ISA) virus is causing significant economic loss for salmon farms. The ISA virus is an orthomyxovirus with two distinct clades, one European and one North American, that diverged before 1900 (Krossøy et al. 2001). This divergence suggests that an ancestral form of the virus was present in wild salmonids prior to

4482-793: The cost of processing. During this same period, farmers began to use steam-powered threshers and tractors . In 1892, the first gasoline-powered tractor was successfully developed, and in 1923, the International Harvester Farmall tractor became the first all-purpose tractor, marking an inflection point in the replacement of draft animals with machines. Mechanical harvesters ( combines ), planters, transplanters, and other equipment were then developed, further revolutionizing agriculture. These inventions increased yields and allowed individual farmers to manage increasingly large farms. The identification of nitrogen , phosphorus , and potassium (NPK) as critical factors in plant growth led to

4565-416: The deterioration of agricultural land and even regenerate soil health and ecosystem services . These developments may fall in the category of organic farming , or the integration of organic and conventional agriculture. Pasture cropping involves planting grain crops directly into grassland without first applying herbicides. The perennial grasses form a living mulch understory to the grain crop, eliminating

4648-513: The early 20th century. Global production was estimated at 21.6 million tonnes in 2017. By 2021, global production of ammonium nitrate was down to 16.7 million tonnes. Ammonium nitrate is found as the natural mineral gwihabaite (formerly known as nitrammite) – the ammonium analogue of saltpetre (mineralogical name: niter) – in the driest regions of the Atacama Desert in Chile , often as

4731-411: The economy and their goal is to sell raw materials or manufactured goods for profit. In the tertiary sector , businesses sell services for profit. Commerce, in contrast to the concept of business discussed above, deals with the movement and distribution of raw materials as well as finished or intermediate (but valuable) goods and services from the manufacturers to the end customers on a large scale. It

4814-712: The entire supply chain . Trade is the exchange of goods (including raw materials , intermediate and finished goods ) and services between buyers and sellers in return for an agreed-upon price at traditional (or online ) marketplaces . It is categorized into domestic trade , including retail and wholesale as well as local, regional, inter-regional and international/foreign trade (encompassing import , export and entrepôt/re-export trades). The exchange of currencies (in foreign exchange markets ), commodities (in commodity markets /exchanges) and securities and derivatives (in stock exchanges and financial markets ) in specialized exchange markets also falls under

4897-587: The food supply . The discovery of vitamins and their role in nutrition , in the first two decades of the 20th century, led to vitamin supplements, which in the 1920s allowed some livestock to be raised indoors, reducing their exposure to adverse natural elements. Following World War II synthetic fertilizer use increased rapidly. The discovery of antibiotics and vaccines facilitated raising livestock by reducing diseases. Developments in logistics and refrigeration as well as processing technology made long-distance distribution feasible. Integrated pest management

In Peru , the Inca made use of otherwise unusable slopes by building drystone walls to create terraces known as Andéns . A paddy field is a flooded parcel of arable land used for growing rice and other semiaquatic crops . Paddy fields are a typical feature of rice-growing countries of east and southeast Asia , including Malaysia, China, Sri Lanka, Myanmar, Thailand, Korea, Japan, Vietnam, Taiwan, Indonesia, India , and

5395-583: The main drivers of global warming , accounting for 14–28% of net greenhouse gas emissions . Many of the negative effects of industrial agriculture may emerge at some distance from fields and farms. Nitrogen compounds from the Midwest, for example, travel down the Mississippi to degrade coastal fisheries in the Gulf of Mexico, causing so-called oceanic dead zones . Many wild plant and animal species have become extinct on

5478-490: The manufacture of synthetic fertilizers , further increasing crop yields . In 1909, the Haber-Bosch method to synthesize ammonium nitrate was first demonstrated. NPK fertilizers stimulated the first concerns about industrial agriculture, due to concerns that they came with side effects such as soil compaction , soil erosion , and declines in overall soil fertility , along with health concerns about toxic chemicals entering

5561-565: The meat, dairy products , eggs , fruits, and vegetables available in supermarkets are produced by such farms. Some intensive farms can use sustainable methods , although this typically necessitates higher inputs of labor or lower yields. Sustainably increasing agricultural productivity , especially on smallholdings , is an important way to decrease the amount of land needed for farming and slow and reverse environmental degradation caused by processes such as deforestation . Intensive animal farming involves large numbers of animals raised on

5644-512: The mid-20th century, the adoption of standardized shipping containers facilitated seamless and efficient intermodal freight transport , leading to a surge in international trade. By the century's end, developing countries saw their share in world trade rise from a quarter to a third. 21st century commerce is increasingly technology-driven (see e-commerce ), globalized , intricately regulated , ethically responsible and sustainability -focused, with multilateral economic integrations (like

5727-559: The need for de-wormers. With the increased productivity of rotational systems, the animals may need less supplemental feed than in continuous grazing systems. Farmers can therefore increase stocking rates. Intensive livestock farming or "factory farming", is the process of raising livestock in confinement at high stocking density. " Concentrated animal feeding operations " (CAFO), or "intensive livestock operations", can hold large numbers (some up to hundreds of thousands) of cows, hogs, turkeys, or chickens, often indoors. The essence of such farms

5810-766: The need to plant cover crops after harvest . The pasture is intensively grazed both before and after grain production. This intensive system yields equivalent farmer profits (partly from increased livestock forage) while building new topsoil and sequestering up to 33 tons of CO 2 /ha/year. Biointensive agriculture focuses on maximizing efficiency such as per unit area, energy input and water input. Agroforestry combines agriculture and orchard/forestry technologies to create more integrated, diverse, productive, profitable, healthy and sustainable land-use systems. Intercropping can increase yields or reduce inputs and thus represents (potentially sustainable) agricultural intensification. However, while total yield per unit land area

5976-676: The reliability of international trans-oceanic shipping and mailing systems and the facility of the Internet has made commerce possible between cities, regions and countries situated anywhere in the world. In the 21st century, Internet-based electronic commerce (where financial information is transferred over Internet), and its subcategories such as wireless mobile commerce and social network -based social commerce have been and continue to get adopted widely. Legislative bodies and ministries or ministerial departments of commerce regulate, promote and manage domestic and foreign commercial activities within

6059-532: The right time, place, quantity, quality and price through various channels from the original producers to the final consumers within local, regional, national or international economies. The diversity in the distribution of natural resources , differences of human needs and wants , and division of labour along with comparative advantage are the principal factors that give rise to commercial exchanges. Commerce consists of trade and aids to trade (i.e. auxiliary commercial services) taking place along

6142-468: The services of commercial agents and agencies. In other words, commerce encompasses a wide array of political, economical, technological, logistical, legal, regulatory, social and cultural aspects of trade on a large scale. From a marketing perspective, commerce creates time and place utility by making goods and services available to the customers at the right place and at the right time by changing their location or placement. Described in this manner, trade

Commerce traces its origins to ancient localized barter systems, leading to the establishment of periodic marketplaces, and culminating in the development of currencies for efficient trade. In medieval times, trade routes (like the Silk Road ) with pivotal commercial hubs (like Venice ) connected regions and continents, enabling long-distance trade and cultural exchange . From

6391-435: The substance are still required to be supervised by authorized personnel and are required to pass a security and national police check before a license may be granted. Ammonium nitrate is not hazardous to health and is usually used in fertilizer products. Ammonium nitrate has an LD 50 of 2217 mg/kg, which for comparison is about two-thirds that of table salt . Ammonium nitrate decomposes, non-explosively, into

6474-405: The system had grown to between 4 and 5 million. Aquaculture is the cultivation of the natural products of water ( fish , shellfish , algae , seaweed , and other aquatic organisms). Intensive aquaculture takes place on land using tanks, ponds, or other controlled systems, or in the ocean, using cages. Intensive farming practices which are thought to be sustainable have been developed to slow

6557-1414: The umbrella of trade. On the other hand, auxiliary commercial activities (aids to trade) which can facilitate trade include commercial intermediaries , banking , credit financing and related services, transportation , packaging , warehousing , communication , advertising and insurance . Their purpose is to remove hindrances related to direct personal contact, payments , savings , funding , separation of place and time, product protection and preservation, knowledge and risk . The broader framework of commerce incorporates additional elements and factors such as laws and regulations (including intellectual property rights and antitrust laws ), policies , tariffs and trade barriers , consumers and consumer trends , producers and production strategies, supply chains and their management , financial transactions for ordinary and extraordinary business activities, market dynamics (including supply and demand ), technological innovation , competition and entrepreneurship , trade agreements , multinational corporations and small and medium-sized enterprisess (SMEs), and macroeconomic factors (like economic stability ). Commerce drives economic growth , development and prosperity , promotes regional and international interdependence , fosters cultural exchange , creates jobs , improves people's standard of living by giving them access to

6640-423: The world. These forms have a 3.6% difference in density and hence transition between them causes a change in volume. One practical consequence of this is that ammonium nitrate cannot be used as a solid rocket motor propellant, as it develops cracks. Stabilized ammonium nitrate (PSAN) was developed as a solution to this and incorporates metal halides stabilisers, which prevent density fluctuations. Ammonium nitrate

6723-453: Was enacted to protect and restore lakes and rivers to a "fishable, swimmable" quality. The United States Environmental Protection Agency identified certain animal feeding operations, along with many other types of industry, as "point source" groundwater polluters. These operations were subjected to regulation. In 17 states in the U.S., isolated cases of groundwater contamination were linked to CAFOs. The U.S. federal government acknowledges

6806-692: Was instrumental in developing wheat cultivars. IR8 , the first widely implemented high-yielding rice to be developed by the International Rice Research Institute , was created through a cross between an Indonesian variety named "Peta" and a Chinese variety named "Dee Geo Woo Gen". With the availability of molecular genetics in Arabidopsis and rice the mutant genes responsible ( reduced height (rht) , gibberellin insensitive (gai1) and slender rice (slr1) ) have been cloned and identified as cellular signalling components of gibberellic acid ,

6889-445: Was once used, in combination with independently explosive "fuels" such as guanidine nitrate , as a cheaper (but less stable) alternative to 5-aminotetrazole in the inflators of airbags manufactured by Takata Corporation , which were recalled as unsafe after killing 14 people. The current USA death total is 27. Numerous safety guidelines are available for storing and handling ammonium nitrate. Health and safety data are shown on
