~9500 BCE: Fertile Crescent farmers begin cultivating founder crops
In the Levant and neighboring parts of the Fertile Crescent, Pre-Pottery Neolithic villagers began sowing emmer and einkorn wheat, barley, lentils, peas, chickpeas, bitter vetch and flax, the eight "founder crops" defined by botanists Daniel Zohary and Maria Hopf. Cultivation of wild stands came first; domesticated forms, such as wheat whose ripe ears no longer shattered, appear from about 10,500 years ago.

Asian rice was domesticated from wild Oryza rufipogon in the Yangtze River basin of China. Cultivation and the selection of domestic traits developed over millennia, with estimates for domestication ranging from about 13,500 to 8,200 years ago. Farmers farther north separately domesticated foxtail and broomcorn millet.

Farmers in southern Mexico domesticated maize from the wild grass teosinte. Genetic studies traced its early domestication to the Balsas River region about 9,000 years ago, while maize residues on tools at the Xihuatoxtla rock shelter dated to about 8,700 years ago. Farming also arose independently in the Andes, Amazonia, New Guinea and parts of Africa.
https://en.wikipedia.org/wiki/Maize~6000 BCE: Samarran farmers dig irrigation canals at Choga Mami
Channels dug beside Choga Mami, a Samarra-culture village in eastern Iraq excavated by Joan and David Oates from 1967, are among the earliest known evidence of canal irrigation, watering wheat, barley and flax. Irrigation later let farming support the cities of southern Mesopotamia, where rainfall was too low for dependable harvests.
https://en.wikipedia.org/wiki/Choga_Mami~3500 BCE: Ox-drawn ards come into use
The ard, or scratch plow, cut a shallow furrow with a pointed wooden tool drawn through the soil. Evidence included ard marks beneath European archaeological sites from about 3500 to 3000 BCE and plow images in Mesopotamian pictographs around 3000 BCE. Animal traction let farmers till larger areas than hand tools alone.
https://en.wikipedia.org/wiki/Ard_(plough)early 1st millennium BCE: Qanats begin carrying groundwater to fields
Qanats, gently sloping tunnels dug back into an upland aquifer and reached by a line of vertical shafts, carried groundwater by gravity to fields and settlements with little loss to evaporation. Most accounts place their origin in Iran in the early 1st millennium BCE, though some argue for southeastern Arabia; the technique spread across Asia and North Africa and, on a large scale, to Muslim-ruled Spain.
https://en.wikipedia.org/wiki/Qanat~256 BCE: Li Bing builds the Dujiangyan irrigation system
In the state of Qin, the official Li Bing directed works on the Min River in Sichuan that split the river with an artificial levee and cut a channel through a hill, diverting water to irrigate the Chengdu Plain and control floods without a dam. Repaired and enlarged by later dynasties, the system still irrigates farmland and was made a World Heritage Site in 2000.
https://en.wikipedia.org/wiki/Dujiangyan8th – 13th centuries: Crops and irrigation spread across the Islamic world
Under the caliphates and their successors, crops such as rice, sugarcane, cotton, citrus and sorghum, and irrigation devices such as the animal-powered saqiyah waterwheel, spread more widely, as far west as al-Andalus in Spain. Historian Andrew Watson called this an "Arab agricultural revolution" in 1974; critics such as Michael Decker argue that many of the crops and techniques were already established under the Romans and Sasanians, though Watson's account of crop diffusion remains influential.
https://en.wikipedia.org/wiki/Arab_Agricultural_Revolution9th – 11th centuries: Northern Europe adopts three-field rotation
Farmers in parts of northern Europe adopted a rotation of winter wheat or rye, spring crops such as oats, peas and beans, and fallow. Two-thirds of the land could bear crops each year, compared with half under a two-field system. Wider use of the heavy moldboard plow also helped cultivation of the region's wet soils.
https://en.wikipedia.org/wiki/Three-field_system1012: Song China spreads fast-ripening Champa rice
Emperor Zhenzong ordered the distribution of seed of drought-tolerant, early-ripening Champa rice to drought-stricken regions. The variety originated in what is now central Vietnam and was already grown in Fujian. Its wider adoption helped extend rice cultivation and made multiple cropping easier in suitable areas.
https://en.wikipedia.org/wiki/Champa_rice1492: Columbus's voyages begin the Columbian exchange
Christopher Columbus's crossing to the Caribbean began a sustained transfer of crops, livestock and diseases between the hemispheres, later named the Columbian exchange by historian Alfred Crosby. Maize, potatoes and cassava became staples across much of Afro-Eurasia, while wheat, sugarcane and livestock spread through the Americas. Introduced epidemics contributed to catastrophic Indigenous population losses.
https://en.wikipedia.org/wiki/Columbian_exchange1640s: Barbados planters turn to sugar and slave labor
Planters on the English colony of Barbados, who had grown tobacco and cotton, switched to sugarcane, drawing on techniques from Dutch-held Brazil, and replaced indentured European servants with enslaved Africans on ever larger estates. Export monoculture worked by enslaved people spread across the Caribbean; historians debate whether this was a "sugar revolution" or, as Russell Menard argued, a "sugar boom" that sped up changes already under way.
https://en.wikipedia.org/wiki/Sugar_plantations_in_the_Caribbean1701: Jethro Tull builds a horse-drawn seed drill
Jethro Tull, a Berkshire landowner trained as a lawyer, built a drill whose grooved rotating cylinder fed seed into a channel opened by a small plow at the front, with a harrow behind to cover it, sowing in rows at a set rate instead of scattering seed by hand. He promoted row sowing and horse hoeing in a 1731 book; multi-tube seed drills had long been used in China, and hand sowing stayed common in England for another century.
https://en.wikipedia.org/wiki/Jethro_Tull_(agriculturist)1730s: Townshend promotes the Norfolk four-course rotation
After leaving office in 1730, the statesman Charles Townshend, 2nd Viscount Townshend, promoted on his Norfolk estate a rotation of wheat, turnips, barley and clover that dropped the fallow year: clover replenished soil nitrogen, while turnips and clover gave fodder that let farmers keep more livestock year-round. The system had developed earlier in Flanders; his advocacy earned him the nickname "Turnip" Townshend.
https://en.wikipedia.org/wiki/Norfolk_four-course_system1750 – 1830: Parliament encloses England's open fields
Parliamentary enclosure, concentrated between 1750 and 1830 with peaks in the 1760s and 1770s and during the wars with France from 1793 to 1815, consolidated scattered open-field strips and common land into compact, privately controlled holdings; more than 5,200 enclosure acts were passed between 1604 and 1914. Historians still debate how much it raised yields, but it extinguished villagers' common rights and concentrated landownership.
https://en.wikipedia.org/wiki/Inclosure_act1786: Meikle builds a practical threshing machine
Andrew Meikle, a Scottish millwright at Houston Mill in East Lothian, built a threshing machine in which fluted rollers fed sheaves to a rotating drum that beat the grain against a curved casing, and patented it in 1788. Driven by horses, water or wind, threshing mills replaced winter work with the flail, and in the Swing Riots of 1830 farm laborers wrecked them across southern and eastern England.
https://en.wikipedia.org/wiki/Andrew_Meikle1831: McCormick demonstrates a horse-drawn reaper
Cyrus McCormick demonstrated a mechanical reaper at Steele's Tavern, Virginia, building on his father Robert's years of experiments and aided by Jo Anderson, a man enslaved by the family; he patented it in 1834, a year after Obed Hussey patented a rival design. After McCormick moved to Chicago in 1847, reapers spread across the grain farms of the Midwest, cutting grain far faster than hand tools could.
https://en.wikipedia.org/wiki/McCormick_reaper1837: John Deere makes a self-scouring steel plow
In Grand Detour, Illinois, blacksmith John Deere made a polished steel plow that shed the sticky prairie soil clogging cast-iron plows. Other makers had already experimented with steel, but Deere built a successful manufacturing business around the design. He moved production to Moline in 1848.
https://en.wikipedia.org/wiki/John_Deere_(inventor)1840: Liebig applies chemistry to plant nutrition
In a widely translated book on organic chemistry in agriculture and physiology, the Giessen chemist Justus von Liebig argued that plants take their carbon from the air, not from humus as was widely held, and need mineral nutrients from the soil that fertilizers could supply. He popularized Carl Sprengel's law of the minimum, that growth is limited by the scarcest nutrient, though for years he wrongly opposed nitrogen fertilizers.
https://en.wikipedia.org/wiki/Justus_von_Liebig1843: Lawes and Gilbert begin the Rothamsted field trials
John Bennet Lawes founded an experimental station on his Rothamsted estate in Hertfordshire, England, and hired chemist Joseph Henry Gilbert. Their Broadbalk experiment compared the effects of manure and inorganic fertilizers on winter wheat. Wheat has been grown every year on all or part of the experiment, which Rothamsted describes as the world's longest-running scientific experiment.
https://en.wikipedia.org/wiki/Rothamsted_Research1862: US creates its agriculture department and land-grant colleges
President Abraham Lincoln signed acts creating the US Department of Agriculture and, in the Morrill Act, granting each state 30,000 acres (about 12,100 hectares) of federal land per member of Congress to endow colleges of agriculture and the mechanic arts; the land had largely been acquired from Native American nations. Federally funded experiment stations (1887) and extension services (1914) were later attached to these land-grant colleges.
https://en.wikipedia.org/wiki/Morrill_Land-Grant_Acts1913: First industrial Haber–Bosch ammonia plant opens
At Oppau, Germany, the chemical company BASF (Badische Anilin- und Soda-Fabrik) began synthesizing ammonia from atmospheric nitrogen and hydrogen, scaling up under Carl Bosch a process Fritz Haber had demonstrated in 1909. Synthetic nitrogen gradually displaced Chilean saltpeter and guano and supplied German explosives makers in World War I; crops grown with it are estimated to have fed 40 to 48 percent of humanity in the 2000s.
https://en.wikipedia.org/wiki/Haber_process1917: Ford mass-produces the Fordson tractor
Henry Ford & Son began mass-producing the Fordson, a small, light tractor without a separate frame, its engine and transmission housings forming the chassis; the first went to Britain's wartime drive to grow more food. Earlier gasoline tractors, such as John Froelich's of 1892 in Iowa, had been built in small numbers; cheap and widely sold, the Fordson helped tractors replace horses and mules over the following decades.
https://en.wikipedia.org/wiki/Fordson1935: Dust Bowl prompts a US soil conservation law
Drought from 1930 turned Great Plains fields, whose deep-rooted native grasses had been plowed up for crops, into sources of dust storms, some carrying topsoil as far as the East Coast, among them the "Black Sunday" storm of April 14. Thirteen days later President Franklin D. Roosevelt signed the Soil Conservation Act, making Hugh Hammond Bennett's Soil Conservation Service a permanent agency to help farmers curb erosion.
https://en.wikipedia.org/wiki/Dust_Bowl1939: Müller discovers DDT's power as an insecticide
Swiss chemist Paul Hermann Müller discovered the insecticidal properties of dichlorodiphenyltrichloroethane (DDT), a compound first synthesized in 1874. Widely used against disease-carrying insects and crop pests, it also accumulated in food chains and harmed wildlife. Rachel Carson's "Silent Spring" helped spur public concern, and the United States canceled most uses in 1972.
https://en.wikipedia.org/wiki/DDT1945: Food and Agriculture Organization founded in Quebec City
Following a 1943 conference called by President Franklin D. Roosevelt at Hot Springs, Virginia, governments founded the UN's Food and Agriculture Organization (FAO) on October 16, with the Scottish nutrition scientist John Boyd Orr as its first director-general. Based in Rome since 1951, it compiles agricultural statistics and gives technical help to member countries, and its founding date is marked each year as World Food Day.
https://en.wikipedia.org/wiki/Food_and_Agriculture_Organization1983: Scientists report the first genetically engineered plants
At the Miami Winter Symposium, three teams, led by Mary-Dell Chilton at Washington University in St. Louis, by Marc Van Montagu and Jeff Schell at Ghent University and by Robert Fraley and colleagues at Monsanto, independently reported using the crown gall bacterium Agrobacterium tumefaciens to transfer antibiotic-resistance genes into tobacco and petunia cells. Van Montagu, Chilton and Fraley shared the 2013 World Food Prize.
https://en.wikipedia.org/wiki/History_of_genetic_engineering1996: Genetically modified crops reach farms at scale
Genetically engineered seeds for major field crops went on sale in the United States, among them Monsanto's Roundup Ready soybeans, which tolerate the herbicide glyphosate, and cotton and corn given an insect-killing gene from the bacterium Bacillus thuringiensis (Bt). Global plantings grew from 1.7 million hectares to 185 million by 2016, mostly soybeans, corn, cotton and canola; in 2025, 96 percent of US soybean acreage was herbicide-tolerant.

Built on the Norwegian Arctic island of Spitsbergen, the vault opened as a backup store for duplicate seed samples from gene banks around the world, which keep ownership of their deposits. The International Center for Agricultural Research in the Dry Areas made the first withdrawal in 2015 to rebuild collections it could no longer maintain in war-torn Syria; by 2025 the vault held more than 1.3 million samples.
https://en.wikipedia.org/wiki/Svalbard_Global_Seed_Vault2026: European Union adopts new rules for gene-edited crops
On June 17 the European Parliament and Council adopted rules for plants produced by certain new genomic techniques. Plants verified as equivalent to conventionally bred varieties would be treated under conventional rules, while more complex modifications would remain under genetically modified organism rules. The regulation provided for application two years after entering into force.
