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
Considerable progress has been made toward collection of baseline data on air emissions from U.S. animal feeding operations. However, limited data exist in the literature regarding turkey air emissions. The project described in this paper continuously monitors ammonia (NH 3 ) and particulate matter (PM) emissions from turkey production houses in Iowa (IA) and Minnesota (MN) for one year, with IA monitoring Hybrid tom turkeys and MN monitoring Hybrid hens. Mobile Air Emission Monitoring Units are used in the continuous monitoring. Data collection and analysis has been ongoing since May 2, 2007 for the IA site and October 9, 2007 for the MN site. Based on the one-year measurement at the IA site involving three flocks, daily NH 3 emissions (g/d-bird) from the IA turkey house varied from 0.04 to 6.4 (mean of 1.9) for flock 1 (May-Aug), 0.2 to 3.4 (mean of 1.3) for flock 2 (Aug-Dec), and 0.16 to 3.8 (mean 1.4) for flock 3 (Dec-Apr). The PM 10 emissions (g/d-bird) were 0.04 to 1.6 (mean of 0.58), 0.04 to 0.39 (mean of 0.2), and 0.04 to 0.82 (mean of 0.37) for flocks 1, 2, and 3, respectively; and the concomitant PM 2.5 emissions (g/d-bird) were 0 to 0.11 (mean of 0.048), 0 to 0.05 (mean of 0.021), and 0 to 0.14 (mean of 0.053) for flocks 1, 2, and 3, respectively. Annual mean emissions from the tom turkeys (including downtime emission), expressed as grams of constituent per bird marketed, were 169 g NH 3 , 40 g PM 10 , and 4.3 g PM 2.5 per bird marketed. Data collection and analysis at the MN site are ongoing.
