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
A general recommendation is to keep ammonia levels in poultry facilities below 25 ppm. Unfortunately, a reliable, inexpensive method of determining ammonia levels has not been well established. To address this situation, ammonia concentrations, as determined by the Ammonia Quick Test and the passive dosimeter tube, were compared to the ammonia concentration determined by the gas detector tube. The ammonia Quick Test estimated ammonia levels accurately at levels of 20-25 ppm of ammonia. The passive dosimeter tubes estimated average ammonia levels accurately at low levels of ammonia. Comparisons of ammonia concentration to relative humidity suggest that ammonia can increase much more rapidly than relative humidity.
