Agricultural Engineering is the area of engineering concerned with the design, construction and improvement of farming equipment and machinery.

Agricultural engineers integrate technology with farming. For example, they design new and improved farming equipment that may work more efficiently, or perform new tasks. They design and build agricultural infrastructure such as dams, water reservoirs, warehouses, and other structures. They may also help engineer solutions for pollution control at large farms. Some agricultural engineers are developing new forms of biofuels from non-food resources like algae and agricultural waste. Such fuels could economically and sustainably replace gasoline without jeopardizing the food supply.

While agricultural engineers may develop specialties, most are involved in certain core activities. For example, most professionals design and test agricultural machinery, equipment, and parts. They may also design food storage structures and food processing plants. Some may design housing and environments for livestock.

Those interested in sustainability may provide advice on water quality and water pollution control issues. They may also plan and oversee land reclamation projects on farms. Others may be involved in agricultural waste-to-energy projects and carbon sequestration (absorbing carbon dioxide from the atmosphere into the soil, crops and trees).
