Research efforts are a valuable component of the Agricultural and Biosystems Engineering Department's mission to the students, faculty, state, region and world. Research is aimed at improving performance and reducing cost at all levels of production with minimal environmental impact. Research is conducted in university labs and in the field, either at four Research and Extension Centers or on producer farms. In addition to research conducted in South Dakota, several faculty members have projects involving international collaboration (e.g., developing biofilter systems on livestock barns in Denmark). Research cooperation with industries that involve agricultural commodities and production has broadened the scope of agricultural engineering research, especially in the development of monitoring sensors and process control systems.
