Agriculture Terms & Definitions

by TeamCFL
agriculture terms

This glossary contains general definitions of agriculture terms related to agricultural ecosystem, production, the environment, sustainable development, organisms or species, the harvested parts, or the harvest in a more refined state.

These agricultural terms were chosen to increase awareness of major agricultural aspects for the nonspecialist and were drawn from various social and natural science disciplines, including ecology, biology, epidemiology, chemistry, sociology, economics, anthropology, philosophy, and public health.

Agriculture Terms and Their Definitions

There are many terms related to different aspects of agriculture that may not be known to those who have not been involved in farming or have very little knowledge. Below, we have defined some common terms and acronyms that are used in agriculture:


A


Acid Soil: A soil with an acid reaction, a pH less than 7.0.

Acre: A parcel of land, containing 4,840 square yards or 43,560 square feet.

Agriculture: The utilization of biological processes on farms to produce food and other products useful and necessary to man. Both a “way of life” and a “means of life” for the people involved in this industry.

Agribusiness: a way of farming that combines agriculture and business and usually involves large amounts of land, animals, and expensive technology.

Agricultural Buildings: From the barn to the farm, agricultural buildings constitute any structures associated with farming or agriculture. Buildings that provide housing for livestock, shelter for plants, or even a structure such as a dam are all considered agricultural buildings.

Agricultural Establishments: An agricultural establishment is defined as a “human establishment for the purpose of agriculture.” These establishments can include agricultural cooperatives, farms, orchards, and even wineries.

Agroecosystem

Agroecosystem: It includes the terms “agro,” which refers to agriculture, and “ecosystem,” which is defined as a community of interacting organisms.  So put them together and what you get is a community of plants and animals. Agroecosystems can be found in everything from farmlands to rangelands.

Agroforestry: On a basic level, agroforestry is defined as “trees on farms.” In actuality, agroforestry involves trees and shrubs being combined with crops and livestock to make for a more productive, healthy, and sustainable-use land system.

Agronomy: The science of crop production and soil management.

Alfalfa: A valuable leguminous crop for forage or hay used in livestock.

Animal Concentration Area (ACA): Barnyards, feedlots, loafing areas, exercise lots or other similar animal confinement areas that will not maintain a growing crop, or where deposited manure nitrogen is in excess of crop needs.

  • This excludes areas managed as pastures or other cropland
  • This excludes pasture access ways if they do not cause a direct flow of nutrients to surface water.

Animal Equivalent Unit (AEU): One thousand pounds of live weight of livestock or poultry animals, on an annualized basis, regardless of the actual number of individual animals in the unit.

Animal Equivalent Unit per Acre (AEU per acre): An animal equivalent unit per acre of cropland or acre of land suitable for the application of animal manure.

Animal Heavy Use Area (AHUA): Barnyard, feedlot, loafing area, exercise lot, or other similar areas on an agricultural operation where, because of the concentration of animals, it is not possible to establish and maintain the vegetative cover of a density capable of minimizing accelerated erosion and sedimentation by usual planting methods.

Animal Unit: A unit of measurement of livestock, the equivalent of one mature cow weighing 1,000 lbs. The measure is used in making comparisons of feed consumption. Five mature ewes also are considered an animal unit.

Annual: A plant that completes its life cycle from seed to plant, flower, and new seed in 1 year or less.

Apiary: Colonies of bees in hives and other beekeeping equipment for the production of honey.

Arable land

Arable land: Basically farmland. Broadly, it can refer to any land capable of growing crops; in a narrower definition, especially for the purpose of agricultural statistics, it is land currently being used for crops (even if temporarily fallow).

Artificial Insemination: The mechanical injection of male semen into the womb of the female with a special syringe-like apparatus. The process begins with the collection of semen from the male. This method is used extensively in dairy husbandry.
