Agrochemical in the context of "Fertilizer"

Intensive agriculture, also known as intensive farming (as opposed to extensive farming), conventional, or industrial agriculture, is a type of agriculture, both of crop plants and of animals, with higher levels of input and output per unit of agricultural land area. It is characterized by a low fallow ratio, higher use of inputs such as capital, labour, agrochemicals and water, and higher crop yields per unit land area.

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 the meat, dairy products, eggs, fruits, and vegetables available in supermarkets are produced by such farms.

The chemical industry comprises the companies and other organizations that develop and produce industrial, specialty and other chemicals. Central to the modern world economy, the chemical industry converts raw materials (oil, natural gas, air, water, metals, and minerals) into commodity chemicals for industrial and consumer products. It includes industries for petrochemicals such as polymers for plastics and synthetic fibers; inorganic chemicals such as acids and alkalis; agricultural chemicals such as fertilizers, pesticides and herbicides; and other categories such as industrial gases, speciality chemicals and pharmaceuticals.

Various professionals are involved in the chemical industry including chemical engineers, chemists and lab technicians.

Near-infrared spectroscopy (NIRS) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum (from 780 nm to 2500 nm). Typical applications include medical and physiological diagnostics and research including blood sugar, pulse oximetry, functional neuroimaging, sports medicine, elite sports training, ergonomics, rehabilitation, neonatal research, brain computer interface, urology (bladder contraction), and neurology (neurovascular coupling). There are also applications in other areas as well such as pharmaceutical, food and agrochemical quality control, atmospheric chemistry, combustion propagation.

The environmental effects of pesticides describe the broad series of consequences of using pesticides. The unintended consequences of pesticides is one of the main drivers of the negative impact of modern industrial agriculture on the environment. Pesticides, because they are toxic chemicals meant to kill pest species, can affect non-target species, such as plants, animals and humans. Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, because they are sprayed or spread across entire agricultural fields. Other agrochemicals, such as fertilizers, can also have negative effects on the environment.

The negative effects of pesticides are not just in the area of application. Runoff and pesticide drift can carry pesticides into distant aquatic environments or other fields, grazing areas, human settlements and undeveloped areas. Other problems emerge from poor production, transport, storage and disposal practices. Over time, repeat application of pesticides increases pest resistance, while its effects on other species can facilitate the pest's resurgence. Alternatives to heavy use of pesticides, such as integrated pest management, and sustainable agriculture techniques such as polyculture mitigate these consequences, without the harmful toxic chemical application.

Agriculture in the Soviet Union was mostly collectivized, with some limited cultivation of private plots. It is often viewed as one of the more inefficient sectors of the economy of the Soviet Union. A number of food taxes (mainly prodrazverstka and prodnalog) were introduced in the early Soviet period despite the Decree on Land that immediately followed the October Revolution. The forced collectivization and class war against (vaguely defined) "kulaks" under Stalinism greatly disrupted farm output in the 1920s and 1930s, contributing to the Soviet famine of 1932–33 (most especially the Holodomor in Ukraine). A system of state and collective farms, known as sovkhozes and kolkhozes, respectively, placed the rural population in a system intended to be unprecedentedly productive and fair but which turned out to be chronically inefficient and lacking in fairness. Under the administrations of Nikita Khrushchev, Leonid Brezhnev, and Mikhail Gorbachev, many reforms (such as Khrushchev's Virgin Lands Campaign) were enacted as attempts to defray the inefficiencies of the Stalinist agricultural system. However, Marxist–Leninist ideology did not allow for any substantial amount of market mechanism to coexist alongside central planning, so the private plot fraction of Soviet agriculture, which was its most productive, remained confined to a limited role. Throughout its later decades the Soviet Union never stopped using substantial portions of the precious metals mined each year in Siberia to pay for grain imports, which has been taken by various authors as an economic indicator showing that the country's agriculture was never as successful as it ought to have been. The real numbers, however, were treated as state secrets at the time, so accurate analysis of the sector's performance was limited outside the USSR and nearly impossible to assemble within its borders. However, Soviet citizens as consumers were familiar with the fact that foods, especially meats, were often noticeably scarce, to the point that not lack of money so much as lack of things to buy with it was the limiting factor in their standard of living.

Despite immense land resources, extensive farm machinery and agrochemical industries, and a large rural workforce, Soviet agriculture was relatively unproductive. Output was hampered in many areas by the climate and poor worker productivity. However, Soviet farm performance was not uniformly bad. Organized on a large scale and relatively highly mechanized, its state and collective agriculture made the Soviet Union one of the world's leading producers of cereals, although bad harvests (as in 1972 and 1975) necessitated imports and slowed the economy. The 1976–1980 five-year plan shifted resources to agriculture, and 1978 saw a record harvest. Conditions were best in the temperate chernozem (black earth) belt stretching from Ukraine through southern Russia into the east, spanning the extreme southern portions of Siberia. In addition to cereals, cotton, sugar beets, potatoes, and flax were also major crops. Such performance showed that underlying potential was not lacking, which was not surprising as the agriculture in the Russian Empire was traditionally amongst the highest producing in the world, although rural social conditions since the October Revolution were hardly improved. Grains were mostly produced by the sovkhozes and kolkhozes, but vegetables and herbs often came from private plots.
