Agricultural and Biosystems Engineering

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

Swine production represents an important economic and social activity in Brazil, however, its traditional exploration is considered by the ambient institutions as an activity of great pollutant potential. The objective of this study was to compare ammonia level in the traditional slatted concrete floor system, a bedded system with wood shavings on top of the concrete floor, or a bedded system with rice hulls on top of the concrete floor. The study was conducted at the EMBRAPA Swine Research Station in Concordia, Santa Catarina, Brazil during August to November 2002. Significant differences among the treatments were observed; the concrete flooring system had the lowest ammonia levels, whereas both bedded systems shared fairly similar levels. However, these measured values in all the treatments were below the threshold level of 20 ppm.
