Since 1905, the Department of Agricultural Engineering, now the Department of Agricultural and Biosystems Engineering (ABE), has been a leader in providing engineering solutions to agricultural problems in the United States and the world. The department’s original mission was to mechanize agriculture. That mission has evolved to encompass a global view of the entire food production system–the wise management of natural resources in the production, processing, storage, handling, and use of food fiber and other biological products.
History
In 1905 Agricultural Engineering was recognized as a subdivision of the Department of Agronomy, and in 1907 it was recognized as a unique department. It was renamed the Department of Agricultural and Biosystems Engineering in 1990. The department merged with the Department of Industrial Education and Technology in 2004.

Abstract
The performances of subsurface drains installed by two different methods (trench and trenchless) were compared using water table depths for two different periods (1980 through 1984 and 1990 through 1991). Data were gathered from a long-term study conducted at Iowa State University’s Northeast Research Center at Nashua, Iowa. Drain installation methods were also evaluated by using the drain outflow data for 1990 and 1991.
