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 sodium hypochlorite and indoxyl acetate tests were compared as methods for quantifying the mechanical damage of soybeans. These methods were selected from six described in the literature. Soybeans at 7 and 21% moisture content were damaged in a Stein Breakage Tester and the remaining whole soybeans were subjected to the two tests. Sodium hypochlorite indicates damage by causing soybeans with cracked hulls to swell whereas the indoxyl acetate test utilizes a dye to stain soybeans with scratched or cracked hulls. The indoxyl acetate test was found to be more sensitive, but the sodium hypochlorite test yielded more consistent data. The hypochlorite test was selected as a suitable test for soybean mechanical damage quantification.
