Agricultural engineering is a discipline that combines engineering science and agricultural knowledge in order to ensure food security. Agricultural engineers deal with the development and improvement of cultivation methods and livestock production systems as well as processing engineering. They eventually design machineries and structures for alternative energy systems such as bioenergy.
Agricultural processing engineering describes all processing steps that an agricultural product runs through before ending on the consumer's table including on-line computer control of food processing operations, modelling heat transfer mechanisms during thermal processing and developing of smart food. It also analyses the foods own characteristics for example the flow behavior of powder and granular food products; aseptic aspects; food biosensors.
Natural resources: Our environment is fragile. The 1930s Dust Bowl and climatic events like the El Niño phenomenon remind us that our soil and water are vulnerable to degradation by both natural and man-made forces. Agricultural engineers with environmental expertise work to better understand the complex mechanics of these resources, so that they can be used efficiently and without degradation. These engineers determine crop water requirements and design irrigation systems.
Power systems and machinery design focuses on designing advanced equipment, making it more efficient and less demanding on our natural resources. They develop equipment for food processing, highly precise crop spraying, agricultural commodity and waste transport, and turf and landscape maintenance, as well as equipment for such specialized tasks as removing seaweed from beaches.
