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 well as to ensure sustainability of natural and renewable resources.[2]

An agricultural engineer is an engineer with an agriculture background. Agricultural engineers make the engineering designs and plans in an agricultural project, usually in partnership with an agriculturist who is more proficient in farming and agricultural science.


The first use of agricultural engineering was the introduction of irrigation in large scale agriculture in the Nile and the Euphrates rivers before 2000 B.C. Large irrigation structures were also present in Baluchistan and India before Christian era. In South America irrigation was practiced in Peru by the Incas and in North America by the Aztecs.

Settlers practiced irrigation in the vicinity of San Antonio in 1715, the Mormons practiced irrigation in Salt Lake Valley in 1847.[3]

With the rise of tractors and machines in the industrial revolution, a new age in Agricultural Engineering began. Over the course of the industrial revolution, mechanical harvesters and planters would replace field hands in most of the food and cash crop industries. In the 20th century, with the rise in reliable engines in airplanes, cropdusters were implemented to disperse pesticides. The introduction of these engineering concepts into the field of agriculture allowed for an enormous boost in the productivity of crops, dubbed a "second agricultural revolution".

In the late 20th century, Genetically Modified Foods (GMOs) were created, giving another large boost to crop yields and resistance to pests.[4]

Role of Agricultural Engineers

Not to be confused with Agriculturist, Farmer, Farmworker, or Geodetic Engineering.

Agricultural engineers may perform tasks such as planning, supervising and managing the building of dairy effluent schemes, irrigation, drainage, flood water control systems, performing environmental impact assessments, agricultural product processing and interpret research results and implement relevant practices. A large percentage of agricultural engineers work in academia or for government agencies. Some are consultants, employed by private engineering firms, while others work in industry, for manufacturers of agricultural machinery, equipment, processing technology, and structures for housing livestock and storing crops. Agricultural engineers work in production, sales, management, research and development, or applied science.


In 2006 Armenia’s agricultural sector accounted for about 20 percent of the GDP’s. After a while the agriculture sector developed and by 2010 in Armenia the agriculture sector comprised about 25 percent of Armenia’s GDP.[5] When looking at the shares of agriculture sector as a GDP’s component and comparing it with Armenia’s neighboring countries, it is obvious that the highest percentage is registered in Armenia. With the 2017 data, the contribution of agriculture to the GDP for the neighboring countries like Georgia, Azerbaijan, Turkey and Iran were 6.88, 5.63, 6.08 and 9.05 respectively.[6]


In the Philippines, the professional designation is Registered Agricultural and Biosystems Engineer. They are licensed and accredited after successfully passing the Agriculturist and Biosystems Engineering Licensure Examination. A prospective Agricultural and Biosystems Engineer is required to have a four-year Bachelor of Science degree in Agricultural and Biosystems Engineering.

The practice of Agricultural and Biosystems Engineering also includes the following:

United Kingdom

In the United Kingdom the term Agricultural Engineer is often also used to describe a person that repairs or modifies agricultural equipment.

United States

The American Society of Agricultural Engineers, now known as the American Society of Agricultural and Biological Engineers (ASABE), was founded in 1907.[7] It is a leading organization in the Agricultural Engineering field. The ASABE provides safety and regulatory standards for the agricultural industry. These standards and regulations are developed on an international scale and include topics on fertilizers, soil conditions, fisheries, biofuels, biogas, feed machinery, tractors, and machinery.[1]
