[3] With growing mechanization and steam power in the Industrial Revolution, a new age in agricultural engineering began.

[3] 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" which consisted of:[6] In the 20th century, with the rise in reliable engines in airplanes, cropdusters were implemented to disperse pesticides.

[5] In the late 20th century, genetically modified foods (GMOs) were created, giving another large boost to crop yields and resistance to pests.

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.

[8] This was and is higher than in Armenia's neighboring countries of Georgia, Azerbaijan, Turkey, and Iran, in which the contribution of agriculture to the GDP in 2017 was 6.88, 5.63, 6.08, and 9.05 percent, respectively.
