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

Manure storage can be a significant source of ammonia emission that impacts the environment. Ammonia emission from manure storage can be controlled by using physical, chemical and/or biological methods. Five treatment agents, including zeolite, liquid Al+Clear (aluminum sulfate), granular Al+Clear (aluminum sulfate), and granular Ferix-3 (ferric sulfate), and PLT (sodium hydrogen sulfate) were topically applied to stored fresh layer manure. Each agent was tested at three application rates, i.e., low, medium and high. Manure was stored in 19-litter Teflon-lined vessels under a constant ambient temperature of 23 oC with a constant airflow of 3 liter per minute. The ammonia concentrations and emissions from the vessels were measured and ammonia emission reductions by the treatment regimens were evaluated as compared to the control. Reduction of ammonia emission as a result of topical application of the tested manure treatment agents, when compared to the control, over a 7-day manure storage period was as following: A) 68%, 81% or 96%, respectively, for zeolite applied at 2.5%, 5% or 10% of the manure weight; B) 63%, 89%, or 94%, respectively, for liquid Al+Clear applied at 1, 2, or 4 kg m-2 of manure surface area; C) 81%, 93%, or 94%, respectively, for dry granular Al+Clear applied at 0.5, 1.0, or 1.5 kg m-2; D) 82%, 86%, or 87%, respectively, for Ferix-3 applied at 0.5, 1.0, or 1.5 kg m-2; and E) 74%, 90%, or 92%, respectively, for PLT applied at 0.5, 1.0, or 1.5 kg m-2.
