Agricultural engineering' is the engineering discipline that applies engineering science and technology to agricultural production and processing, living systems, and to the management of natural resources. The first curriculum in Agricultural Engineering was established at Iowa State University by J. B. Davidson in 1905. The American Society of Agricultural Engineers, now known as the American Society of Agricultural and Biological Engineers, was founded in 1907.
Agricultural engineers design agricultural machinery, equipment, and agricultural structures. Agricultural Engineers may perform tasks as planning, supervising and managing the building of dairy effluent schemes, irrigation, drainage, flood and water control systems, perform environmental impact assessments and interpret research results and implement relevant practices.
Some specialties include power systems and machinery design; structures and environmental science; and food and bioprocess engineering. They develop ways to conserve soil and water and to improve the processing of agricultural, food, and biorenewable products.
A large percentage of agricultural engineers work in academia or for government agencies such as the United States Department of Agriculture or state agricultural extension services. Many are employed by manufacturers of agricultural machinery and equipment. Agricultural engineers work in production, sales, management, research and development, or applied science.
