Agricultural science (or agriscience for short [1] ) is a broad multidisciplinary field of biology that encompasses the parts of exact, natural, economic and social sciences that are used in the practice and understanding of agriculture. Professionals of the agricultural science are called agricultural scientists or agriculturists.
In the 18th century, Johann Friedrich Mayer conducted experiments on the use of gypsum (hydrated calcium sulfate) as a fertilizer. [2]
In 1843, John Bennet Lawes and Joseph Henry Gilbert began a set of long-term field experiments at Rothamsted Research in England, some of which are still running as of 2018. [3] [4] [5]
In the United States, a scientific revolution in agriculture began with the Hatch Act of 1887, which used the term "agricultural science". [6] [7] The Hatch Act was driven by farmers' interest in knowing the constituents of early artificial fertilizer. The Smith–Hughes Act of 1917 shifted agricultural education back to its vocational roots, but the scientific foundation had been built. [8] For the next 44 years after 1906, federal expenditures on agricultural research in the United States outpaced private expenditures. [9] : xxi
Agriculture, agricultural science, and agronomy are closely related. However, they cover different concepts:
Agricultural sciences include research and development on: [11] [12]
A fertilizer or fertiliser is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments. Many sources of fertilizer exist, both natural and industrially produced. For most modern agricultural practices, fertilization focuses on three main macro nutrients: nitrogen (N), phosphorus (P), and potassium (K) with occasional addition of supplements like rock flour for micronutrients. Farmers apply these fertilizers in a variety of ways: through dry or pelletized or liquid application processes, using large agricultural equipment, or hand-tool methods.
The following outline is provided as an overview of and topical guide to agriculture:
Agronomy is the science and technology of producing and using plants by agriculture for food, fuel, fiber, chemicals, recreation, or land conservation. Agronomy has come to include research of plant genetics, plant physiology, meteorology, and soil science. It is the application of a combination of sciences such as biology, chemistry, economics, ecology, earth science, and genetics. Professionals of agronomy are termed agronomists.
The following outline is provided as an overview of and topical guide to sustainable agriculture:
Good agricultural practice (GAP) is a certification system for agriculture, specifying procedures that must be implemented to create food for consumers or further processing that is safe and wholesome, using sustainable methods. While there are numerous competing definitions of what methods constitute good agricultural practice, there are several broadly accepted schemes that producers can adhere too.
Agroecology is an academic discipline that studies ecological processes applied to agricultural production systems. Bringing ecological principles to bear can suggest new management approaches in agroecosystems. The term can refer to a science, a movement, or an agricultural practice. Agroecologists study a variety of agroecosystems. The field of agroecology is not associated with any one particular method of farming, whether it be organic, regenerative, integrated, or industrial, intensive or extensive, although some use the name specifically for alternative agriculture.
The history of agricultural science is a sub-field of the history of agriculture which looks at the scientific advancement of techniques and understanding of agriculture. Early study of organic production in botanical gardens was continued in with agricultural experiment stations in several countries.
An agricultural experiment station (AES) or agricultural research station (ARS) is a scientific research center that investigates difficulties and potential improvements to food production and agribusiness. Experiment station scientists work with farmers, ranchers, suppliers, processors, and others involved in food production and agriculture.
Agrophysics is a branch of science bordering on agronomy and physics, whose objects of study are the agroecosystem - the biological objects, biotope and biocoenosis affected by human activity, studied and described using the methods of physical sciences. Using the achievements of the exact sciences to solve major problems in agriculture, agrophysics involves the study of materials and processes occurring in the production and processing of agricultural crops, with particular emphasis on the condition of the environment and the quality of farming materials and food production.
An agriculturist, agriculturalist, agrologist, or agronomist is a professional in the science, practice, and management of agriculture and agribusiness. It is a regulated profession in Canada, India, the Philippines, the United States, and the European Union. Other names used to designate the profession include agricultural scientist, agricultural manager, agricultural planner, agriculture researcher, or agriculture policy maker.
Agricultural soil science is a branch of soil science that deals with the study of edaphic conditions as they relate to the production of food and fiber. In this context, it is also a constituent of the field of agronomy and is thus also described as soil agronomy.
North Carolina State University's College of Agriculture and Life Sciences (CALS) is the fourth largest college in the university and one of the largest colleges of its kind in the nation, with nearly 3,400 students pursuing associate, bachelor's, master's and doctoral degrees and 1,300 on-campus and 700 off-campus faculty and staff members.
The Institut national de la recherche agronomique was a French public research institute dedicated to agricultural science. It was founded in 1946 and is a Public Scientific and Technical Research Establishment under the joint authority of the Ministries of Research and Agriculture. From 1 January 2020 the INRA merged with the IRSTEA to create the INRAE.
The University of Maryland College of Agriculture and Natural Resources is the agricultural and environmental sciences college of the University of Maryland and operates the Maryland Sea Grant College in cooperation with the University of Maryland Center for Environmental Science and the National Oceanic and Atmospheric Administration.
William Albert Albrecht chairman of the Department of Soils at the University of Missouri, was the foremost authority on the relation of soil fertility to human health and earned four degrees from the University of Illinois at Urbana–Champaign. As emeritus professor of soils at the University of Missouri, he saw a direct link between soil quality, food quality and human health. He drew direct connections between poor quality forage crops, and ill health in livestock and from this developed a formula for ideal ratios of cations in the soil, the Base Cation Saturation Ratio. While he did not discover cation exchange in the soil as is sometimes supposed, he may have been the first to associate it with colloidal clay particles. He served as 1939 President of the Soil Science Society of America.
Twenty years before the phrase 'environmental concern' crept into the national consciousness, he was lecturing from coast to coast on the broad topic of agricultural ecology.
" The soil is the ‘creative material’ of most of the basic needs of life. Creation starts with a handful of dust.” Dr. William A. Abrecht.

The Indian Institute of Soil Science is an autonomous institute for higher learning, established under the umbrella of Indian Council of Agricultural Research (ICAR) by the Ministry of Agriculture, Government of India for advanced research in the field of soil sciences.
The Lilongwe University of Agriculture and Natural Resources (LUANAR) is a university outside Lilongwe, Malawi. It was formed in 2011 by a merger between Bunda College of Agriculture of the University of Malawi and Natural Resources College (NRC).
Cynthia Grant is a former Canadian federal scientist who is an expert in soil fertility and crop nutrition. She was a researcher with Agriculture and Agri-Food Canada (AAFC) (1986–2015). Her research provided the scientific foundation for the Made-in-Canada 4R nutrient stewardship framework that applies crop nutrients from the right source and at the right rate, time and place. Grant is now part of an elite group of ten women who have been inducted into the Canadian Agricultural Hall of Fame since 1960.
