Agricultural engineers may perform tasks such as planning, supervising and managing the building of dairy effluent schemes, irrigation, drainage, flood and 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 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.

The agricultural engineer can be found working with industries associated with agriculture such as equipment companies, seed manufacturers and food companies / distributors. Some agricultural engineers like to work directly with farmers and agricultural technicians to solve issues with crop, land and livestock. Large farm operations may consult or hire agricultural engineers to resolve management and technical issues. A good number of engineers work for government agencies that oversee agricultural entities.

The agricultural engineer has plenty to do as increasing biological discoveries are adopted to farming practices like on-farm energy production. New uses for agricultural waste are becoming evident and crops are yielding not only food but new byproducts. The continuing cost of agricultural operations and our increasing populations mean career opportunities for agricultural engineers should always be in demand.
