Agricultural science 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.
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.
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 American Society of Agronomy (ASA) is a scientific and professional society of agronomists and scientists of related disciplines, principally in the United States but with many non-U.S. members as well.
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.
Energy & Environment is an academic journal "covering the direct and indirect environmental impacts of energy acquisition, transport, production and use". Under its editor-in-chief from 1998 to 2017, Sonja Boehmer-Christiansen, it was known for easygoing peer-review and publishing climate change denial papers. Yiu Fai Tsang became its editor-in-chief in May 2017.
George Demas was an American pedologist whose pioneering studies of subaqueous soil contributed to the understanding of soil formation and the expansion of the concept of soil. USDA soil taxonomy was revised as a result.
Abdul Rashid, is a Pakistani agricultural scientist, who has served as a Member (Bio-sciences) of the Pakistan Atomic Energy Commission (PAEC) from 2008 to 2011 and Director General of Pakistan's National Agricultural Research Center (NARC) from 2006 to 2008. He received a Ph.D. from the University of Hawaii at Manoa, Hawaii, in the United States.
Base-cation saturation ratio (BCSR) is a method of interpreting soil test results that is widely used in sustainable agriculture, supported by the National Sustainable Agriculture Information Service (ATTRA) and claimed to be successfully in use on over a million acres (4,000 km2) of farmland worldwide. The traditional method, as used by most university laboratories, is known variously as the 'sufficiency level', sufficiency level of available nutrients (SLAN), or Index(UK) system. The sufficiency level system is concerned only with keeping plant-available nutrient levels within a well studied range, making sure there is neither a deficiency nor an excess. In the BCSR system, soil cations are balanced according to varying ratios often stated as giving 'ideal' or 'balanced' soil. These ratios can be between individual cations, such as the calcium to magnesium ratio, or they may be expressed as a percentage saturation of the cation exchange capacity (CEC) of the soil. Most 'ideal soil' theories stress both approaches.
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 International Year of Soils, 2015 was declared by the Sixty-eighth session of the United Nations General Assembly on December 20, 2013, after recognizing December 5 as World Soil Day.
BAITSSS is biophysical Evapotranspiration (ET) computer model that determines water use, primarily in agriculture landscape, using remote sensing-based information. It was developed and refined by Ramesh Dhungel and the water resources group at University of Idaho's Kimberly Research and Extension Center since 2010. It has been used in different areas in the United States including Southern Idaho, Northern California, northwest Kansas, Texas, and Arizona.
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.
Robert August Olson was an American soil scientist. He was a professor of agronomy at the University of Nebraska–Lincoln, and one of the first to prove and warn that nitrogen fertilizers could harm crops and pollute groundwater.
The Vadose Zone Journal is a peer-reviewed scientific journal established in 2002 and published by John Wiley & Sons on behalf of the Soil Science Society of America. It covers research on the vadose zone from across a wide range of disciplines. Since 2018, the journal is published open access.
Rattan Lal is a soil scientist. His work focuses on regenerative agriculture through which soil can help resolve global issues such as climate change, food security and water quality. He is considered a pioneer in soil-centric agricultural management to improve global food security and develop climate-resilient agriculture.
The Crop Science Society of America (CSSA) is a scientific and professional society of plant biologists and crop scientists based in the United States.
Elizabeth Lee "Betty" Klepper was an American agronomic scientist from Memphis, Tennessee.
David J. Mulla is an American soil scientist. He played an role in the organization of the International Conference on Precision Agriculture (ICPA), which started as a small workshop in Minneapolis in the early 1990s and developed into the International Society of Precision Agriculture (ISPA). Until 2008, the meetings of the ICPA were hosted by the University of Minnesota. In 2013, he published a review of advances in remote sensing for precision agriculture.
Paramu Mafongoya is a Zimbabwean professor at the University of KwaZulu-Natal (UKZN) in South Africa, where he specialises in agriculture, earth and environmental sciences. He serves as the South African Research Chair (SARChI) in Agronomy and Rural Development at UKZN. He is affiliated with the African Academy of Sciences (AAS) and the Zimbabwe Academy of Sciences (ZAS). His work in agricultural research, development, education, and integrated natural resources management extends over three decades.
