Agricultural engineering is the engineering discipline that applies engineering science and technology to agricultural production and processing. Agricultural engineering combines the disciplines of animal biology, plant biology, and mechanical, civil, electrical and chemical engineering principles with knowledge of agricultural principles.

Subfields:

Some of the specialties of agricultural engineers include:

• The design of agricultural machinery, equipment, and agricultural structures
• crop production, including seeding, tillage, irrigation and the conservation of soil and water
• animal production, including the care and processing of poultry and fish and dairy management
• The processing of food and other agricultural and biorenewable products, and food engineering.
• Bioresource engineering, this uses machines on the molecular level to help the environment.

Agricultural Engineers:

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, agricultural productprocessing and interpret research results and implement relevant practices. 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. 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.
