and its dependable seasonal flooding. The river's predictability and the fertile soil allowed the Egyptians to build an empire on the basis of great agricultural wealth. Egyptians were among the first peoples to practice agriculture on a large scale, starting in the pre-dynastic period from the end of the Paleolithic into the Neolithic, between around 10,000 BC and 4000 BC. This was made possible with the development of basin irrigation. Their staple food crops were grains such as wheat and barley, alongside industrial crops such as

In the Seleucid Empire, Mesopotamia was a crucial area for the production of wheat, while nomadic animal husbandry was also practiced in other parts.Helmut Koester (1995), ''History, Culture, and Religion of the Hellenistic Age'', 2nd edition, New York: Walter de Gruyter, , p. 77.


Roman Empire

In the Greco-Roman world of Classical antiquity, Roman agriculture was built on techniques originally pioneered by the Sumerians, transmitted to them by subsequent cultures, with a specific emphasis on the cultivation of crops for trade and export. Ancient Rome, The Romans laid the groundwork for the
manorial Manorialism, also known as the manor system or manorial system, was the method of land ownership (or "tenure") in parts of Europe, notably France and later England, during the Middle Ages. Its defining features included a large, sometimes forti ...
economic system, involving serfdom, which flourished in the Middle Ages. The farm sizes in History of Rome, Rome can be divided into three categories. Small farms were from 18 to 88 iugera (one iugerum is equal to about 0.65 acre). Medium-sized farms were from 80 to 500 iugera (singular iugerum). Large estates (called latifundia) were over 500 iugera. Roman Empire, The Romans had four systems of farm management: direct work by the owner and his family; slaves doing work under the supervision of slave managers; Tenant farmer, tenant farming or sharecropping in which the owner and a tenant divide up a farm's produce; and situations in which a farm was leased to a tenant.White, K. D. (1970), ''Roman Farming'' (Cornell University Press)


The Americas

Agricultural history took a different path from the Old World as the Americas lacked large-seeded, easily domesticated grains (such as wheat and barley) and large domestic animals that could be used for agricultural labor. Rather than the practice which developed in the Old World of sowing a field with a single crop, pre-historic American agriculture usually consisted of cultivating many crops close to each other utilizing only hand labor. Moreover, agricultural areas in the Americas lacked the uniformity of the east–west area of Mediterranean climate, Mediterranean and semi-arid climates in southern Europe and southwestern Asia, but instead had a north–south pattern with a variety of different climatic zones which fostered the domestication of many different plants. At the time of first contact between the Europeans and the Americans, the Europeans practiced "extensive agriculture, based on the plough and draught animals," with tenants under landlords, but also forced labor or slavery, while the Indigenous peoples of the Americas practiced "intensive agriculture, based on human labour." Europeans wanted control of land for the grazing of their livestock and property rights for the control of production. Though they were impressed with the productivity of traditional farming techniques, they saw no connection to their system and were dismissive of Native American practices as "gardening" rather than a commercializable enterprise. The hemisphere's most important crop,

, became more productive than Old World grain crops, after several thousand years of selective breeding, producing two and one half times more calories per acre than wheat and barley.


South America

The earliest known areas of possible agriculture in the Americas dating to about 9000 BC are in Colombia, near present-day Pereira, Colombia, Pereira, and by the Las Vegas culture (archaeology), Las Vegas culture in Ecuador on the Santa Elena Province, Santa Elena peninsula. The plants cultivated (or manipulated by humans) were Goeppertia allouia, leren (''Calathea allouia''), Maranta arundinacea, arrowroot (''Maranta arundinacea''),

(''Cucurbita'' species), and Calabash, bottle gourd (''Lagenaria siceraria''). All are plants of humid climates and their existence at this time on the semi-arid Santa Elena peninsula may be evidence that they were transplanted there from more humid environments. In another study, this area of South America was identified as one of the four oldest places of origin for agriculture, along with the Fertile Crescent, China, and Mesoamerica, dated between 6200 BC and 10000 BC. (To facilitate comprehension by readers, Radiocarbon dating, Radiocarbon calibrated BP dates in the above sources have been converted to BC.)

, the Aztecs were active farmers and had an agriculturally focused economy. The land around Lake Texcoco was fertile, but not large enough to produce the amount of food needed for the population of their expanding empire. The Aztecs developed irrigation systems, formed Terrace (agriculture), terraced hillsides, fertilized their soil, and developed chinampas or artificial islands, also known as "floating gardens". The Maya civilization, Mayas between 400 BC to 900 AD used extensive canal and raised field systems to farm swampland on the Yucatán Peninsula.


North America

The indigenous people of the Eastern Agricultural Complex, Eastern U.S. domesticated numerous crops. Sunflowers, tobacco, varieties of squash and ''Chenopodium'', as well as crops no longer grown, including Iva annua, marsh elder and Hordeum pusillum, little barley. Wild foods including wild rice and maple sugar were harvested. The domesticated strawberry is a hybrid of a Chilean and a North American species, developed by breeding in Europe and North America. Two major crops, pecans and Concord grapes, were used extensively in prehistoric times but do not appear to have been domesticated until the 19th century. The Agriculture in the prehistoric Southwest, indigenous people in what is now California and the Pacific Northwest practiced various forms of

The beans provide the nitrogen to the soil that the other plants use, and the squash spreads along the ground, blocking the sunlight, helping prevent the establishment of weeds. The squash leaves also act as a "living mulch".


Australia

Indigenous Australians were predominately nomadic hunter-gatherers. Due to the policy of ''terra nullius'', Aboriginals were regarded as not having been capable of sustained agriculture. However, the current consensus is that various agricultural methods were employed by the indigenous people. In two regions of Central Australia, the central west coast and eastern central Australia, forms of agriculture were practiced. People living in permanent settlements of over 200 residents sowed or planted on a large scale and stored the harvested food. The Nhanda and Amangu of the central west coast grew yams (''Dioscorea, Dioscorea hastifolia''), while various groups in eastern central Australia (the Corners Region) planted and harvested bush onions (''yaua'' – ''Cyperus bulbosus''), native millet (''cooly, tindil'' – ''Panicum decompositum'') and a Sporocarp (ferns), sporocarp, ''ngardu'' (''Marsilea drummondii''). Indigenous Australians used systematic burning, fire-stick farming, to enhance natural productivity. In the 1970s and 1980s archaeological research in south west Victoria established that the Gunditjmara and other groups had developed sophisticated eel farming and fish trapping systems over a period of nearly 5,000 years. The archaeologist Harry Lourandos suggested in the 1980s that there was evidence of 'intensification' in progress across Australia, a process that appeared to have continued through the preceding 5,000 years. These concepts led the historian Bill Gammage to argue that in effect the whole continent was a managed landscape. Torres Strait Islanders are now known to have planted

saw further improvements in agriculture. Monastery, Monasteries spread throughout Europe and became important centers for the collection of knowledge related to agriculture and forestry. The manorial system allowed large landowners to control their land and its laborers, in the form of peasants or serfs. During the medieval period, the Arab world was critical in the exchange of crops and technology between the European, Asia and African continents. Besides transporting numerous crops, they introduced the concept of summer irrigation to Europe and developed the beginnings of the plantation system of

s, hand tools and horse shoes. The carruca heavy plough improved on the earlier scratch plough, with the adoption of the Chinese mouldboard plough to turn over the heavy, wet soils of northern Europe. This led to the clearing of northern European forests and an increase in agricultural production, which in turn led to an increase in population. At the same time, some farmers in Europe moved from a two field

to a three field crop rotation in which one field of three was left fallow every year. This resulted in increased productivity and nutrition, as the change in rotations permitted nitrogen-fixing legumes such as peas, lentils and beans. Improved horse harnesses and the whippletree (mechanism), whippletree further improved cultivation. Watermills were introduced by the Romans, but were improved throughout the Middle Ages, along with windmills, and used to grind grains into flour, to cut wood and to process flax and wool. Crops included wheat, rye, barley and oats. Peas, beans, and vetches became common from the 13th century onward as a fodder crop for animals and also for their nitrogen-fixation fertilizing properties. Crop yields peaked in the 13th century, and stayed more or less steady until the 18th century. Though the limitations of medieval farming were once thought to have provided a ceiling for the population growth in the Middle Ages, recent studies have shown that the technology of medieval agriculture was always sufficient for the needs of the people under normal circumstances, and that it was only during exceptionally harsh times, such as the Great Famine of 1315–1317, terrible weather of 1315–17, that the needs of the population could not be met.


Arab world

From the 8th century to the 14th century, the Islamic Golden Age, Islamic world underwent a transformation in agricultural practice, described by the historian Andrew Watson as the Arab agricultural revolution. This transformation was driven by a number of factors including the diffusion of many crops and plants along Muslim trade routes, the spread of more advanced farming techniques, and an agricultural-economic system which promoted increased yields and efficiency. The shift in agricultural practice changed the economy, population distribution, vegetation cover, agricultural production, population levels, Urbanization, urban growth, the distribution of the labour force, cooking, diet, and clothing across the Islamic world. Muslim traders covered much of the Old World, and trade enabled the diffusion of many crops, plants and farming techniques across the region, as well as the adaptation of crops, plants and techniques from beyond the Islamic world. This diffusion introduced major crops to Europe by way of

s traveled from the Old World to the New. There had been few livestock species in the New World, with horses, cattle, sheep and goats being completely unknown before their arrival with Old World settlers. Crops moving in both directions across the Atlantic Ocean caused population growth around the world and a lasting effect on many cultures in the Early modern period, Early Modern period. Maize and cassava were introduced from Brazil into Africa by Portuguese traders in the 16th century, becoming staple foods, replacing native African crops. After its introduction from South America to Spain in the late 1500s, the potato became a staple crop throughout Europe by the late 1700s. The potato allowed farmers to produce more food, and initially added variety to the European diet. The increased supply of food reduced disease, increased births and reduced mortality, causing a population boom throughout the British Empire, the US and Europe. The introduction of the potato also brought about the first intensive use of fertilizer, in the form of guano imported to Europe from Peru, and the first artificial pesticide, in the form of an arsenic compound used to fight Colorado potato beetles. Before the adoption of the potato as a major crop, the dependence on grain had caused repetitive regional and national famines when the crops failed, including 17 major famines in England between 1523 and 1623. The resulting dependence on the potato however caused the European Potato Failure, a disastrous crop failure from potato blight, disease that resulted in widespread Great Famine (Ireland), famine and the death of over one million people in Ireland alone.

Modern agriculture


British agricultural revolution

Between the 17th century and the mid-19th century, Britain saw a large increase in agricultural productivity and net output. New agricultural practices like enclosure, mechanization, four-field crop rotation to maintain soil nutrients, and

enabled an Malthusian trap, unprecedented population growth to 5.7 million in 1750, freeing up a significant percentage of the workforce, and thereby helped drive the Industrial Revolution. The productivity of wheat went up from per acre in 1720 to around by 1840, marking a major turning point in history. Advice on more productive techniques for farming began to appear in England in the mid-17th century, from writers such as Samuel Hartlib, Walter Blith and others. The main problem in sustaining agriculture in one place for a long time was the depletion of nutrients, most importantly nitrogen levels, in the soil. To allow the soil to regenerate, productive land was often let fallow and in some places

was used. The Dutch four-field rotation system was popularised by the British agriculturist Charles Townshend, 2nd Viscount Townshend, Charles Townshend in the 18th century. The system (wheat, turnips, barley and clover), opened up a fodder crop and grazing crop allowing livestock to be bred year-round. The use of clover was especially important as the legume roots replenished soil nitrates. The mechanisation and rationalisation of agriculture was another important factor. Robert Bakewell (farmer), Robert Bakewell and Thomas Coke, 1st Earl of Leicester (seventh creation), Thomas Coke introduced

, and initiated a process of inbreeding to maximise desirable traits from the mid 18th century, such as the New Leicester sheep. Machines were invented to improve the efficiency of various agricultural operation, such as Jethro Tull (agriculturist), Jethro Tull's seed drill of 1701 that mechanised seeding at the correct depth and spacing and Andrew Meikle's threshing machine of 1784. Ploughs were steadily improved, from Joseph Foljambe's Plough#Heavy Ploughs, Rotherham iron plough in 1730 to James Small (inventor), James Small's improved "Scots Plough" metal in 1763. In 1789 Ransomes, Sims & Jefferies was producing 86 plough models for different soils. Powered farm machinery began with Richard Trevithick's stationary steam engine, used to drive a threshing machine, in 1812. Mechanisation spread to other farm uses through the 19th century. The first petrol-driven tractor was built in America by John Froelich in 1892. John Bennet Lawes began the scientific investigation of fertilization at the Rothamsted Experimental Station in 1843. He investigated the impact of inorganic and organic fertilizers on crop yield and founded one of the first artificial fertilizer manufacturing factories in 1842. Fertilizer, in the shape of sodium nitrate deposits in Chile, was imported to Britain by John Thomas North as well as guano (birds droppings). The first commercial process for fertilizer production was the obtaining of super phosphate, phosphate from the dissolution of coprolites in sulphuric acid.


20th century

Dan Albone constructed the first commercially successful gasoline-powered general purpose tractor in 1901, and the 1923 International Harvester Farmall tractor marked a major point in the replacement of draft animals (particularly horses) with machines. Since that time, self-propelled mechanical harvesters (combine harvester, combines), Planter (farm implement), planters, transplanters and other equipment have been developed, further revolutionizing agriculture. These inventions allowed farming tasks to be done with a speed and on a scale previously impossible, leading modern farms to output much greater volumes of high-quality produce per land unit.

to overcome previous constraints. It was first patented by German chemist Fritz Haber. In 1910 Carl Bosch, while working for German chemical company BASF, successfully commercialized the process and secured further patents. In the years after World War II, the use of synthetic fertilizer increased rapidly, in sync with the increasing world population. Collective farming was widely practiced in the Soviet Union, the Eastern Bloc countries, China, and Vietnam, starting in the 1930s in the Soviet Union; one result was the Soviet famine of 1932–33. Another consequence occurred during the Great Leap Forward in China initiated by Mao Tse-tung that resulted in the Great Chinese Famine from 1959 to 1961 and ultimately reshaped the thinking of Deng Xiaoping. In the past century agriculture has been characterized by increased productivity, the substitution of synthetic fertilizers and pesticides for labour,

s such as Ethanol fuel, ethanol. The number of people involved in farming in industrial countries fell radically from 24 percent of the American population to 1.5 percent in 2002. The number of farms also decreased and their ownership became more concentrated; for example, between 1967 and 2002, one million pig farms in America consolidated into 114,000, with 80 percent of the production on factory farms. According to the Worldwatch Institute, 74 percent of the world's poultry, 43 percent of beef, and 68 percent of eggs are produced this way. Famines however continued to sweep the globe through the 20th century. Through the effects of climatic events, government policy, war and crop failure, millions of people died in each of at least ten famines between the 1920s and the 1990s.


Green Revolution

The Green Revolution was a series of research, development, and technology transfer initiatives, between the 1940s and the late 1970s. It increased agriculture production around the world, especially from the late 1960s. The initiatives, led by Norman Borlaug and credited with saving over a billion people from starvation, involved the development of high-yielding varieties of cereal grains, expansion of irrigation infrastructure, modernization of management techniques, distribution of hybridized seeds, synthetic fertilizers, and

s to farmers. Synthetic nitrogen, along with mined rock phosphate, pesticides and mechanization, have greatly increased crop yields in the early 20th century. Increased supply of grains has led to cheaper livestock as well. Further, global yield increases were experienced later in the 20th century when high-yield varieties of common staple grains such as rice, wheat, and corn were introduced as a part of the Green Revolution. The Green Revolution exported the technologies (including pesticides and synthetic nitrogen) of the developed world to the developing world. Thomas Malthus famously predicted that the Earth would not be able to support its growing population, but technologies such as the Green Revolution have allowed the world to produce a surplus of food. Although the Green Revolution at first significantly increased rice yields in Asia, yield then levelled off. The genetic "yield potential" has increased for wheat, but the yield potential for rice has not increased since 1966, and the yield potential for maize has "barely increased in 35 years". It takes only a decade or two for herbicide-resistant weeds to emerge, and insects become resistant to insecticides within about a decade, delayed somewhat by crop rotation.


Organic agriculture

For most of its history, agriculture has been organic agriculture, organic, without synthetic fertilisers or pesticides, and without GMOs. With the advent of chemical agriculture, Rudolf Steiner called for farming without synthetic pesticides, and his Agriculture Course of 1924 laid the foundation for biodynamic agriculture. Lord Northbourne developed these ideas and presented his manifesto of
organic farming Organic farming, also known as ecological farming or biological farming,Labelling, article 30 o''Regulation (EU) 2018/848 of the European Parliament and of the Council of 30 May 2018 on organic production and labelling of organic products and re ...
in 1940. This became a worldwide movement, and organic farming is now practiced in many countries.
