Agronomy, generally known as agriculture, 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 .
Agricultural extension – once known as the application of scientific research and new knowledge to agricultural practices through farmer education. The field of extension now encompasses a wider range of communication and learning activities organised for rural people by professionals from different disciplines, including agriculture ...
Other applications of scientific research since 1950 in agriculture include gene manipulation, [182] [183] hydroponics, [184] and the development of economically viable biofuels such as ethanol. [185] 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.
Agricultural economics is an applied field of economics concerned with the application of economic theory in optimizing the production and distribution of food and fiber products. Agricultural economics began as a branch of economics that specifically dealt with land usage. It focused on maximizing the crop yield while maintaining a good soil ...
Agricultural engineering, also known as agricultural and biosystems engineering, is the field of study and application of engineering science and designs principles for agriculture purposes, combining the various disciplines of mechanical, civil, electrical, food science, environmental, software, and chemical engineering to improve the efficiency of farms and agribusiness enterprises [1] as ...
Agriculture encompasses crop and livestock production, aquaculture, and forestry for food and non-food products. [1] Agriculture was a key factor in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in the cities. While humans started gathering grains at least ...
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.
Precision agriculture often employs technologies to automate agricultural operations, improving their diagnosis, decision-making or performing. [4] [5] The goal of precision agriculture research is to define a decision support system for whole farm management with the goal of optimizing returns on inputs while preserving resources. [6] [7]
