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
This study was focused on the economic impact of corn residue harvest systems on typical grain harvesting. In Chapter 2, the single-pass stover harvest system with several equipment application logistics is examined; in Chapter 3, both existing and potential single-pass cob harvest systems were evaluated with respect to harvest work time length, equipment and labor requirements, harvest cost, and post-harvest costs related to residue collection. Residue collection actually increased harvest time due to the lower harvest rate caused by additional material passing through the combine. Field traffic increased as additional equipment is required during harvesting; an increased labor requirement was also an important result in all harvest scenarios. In the stover single-pass harvest scenario, increasing on-board stover density helped to significantly reduce equipment and labor requirements. Nutrient replacement and long-term field side storage needs related to the residue harvest also contributed to harvest cost and could not be neglected.
