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
Following harvest, corn raised for grain is subject to infection and deterioration due to storage fungi. Laboratory storage studies done on yellow dent corn in the 1960s established dry matter loss, as estimated by CO2 evolution during storage, to be a usable indicator of corn deterioration during storage. As a result of these studies, equations were developed to predict CO2 evolution of stored corn as a function of moisture content, temperature, and mechanical damage level. Later research has added information on genetic hybrid resistance to fungal growth and fungicide effects. This article assembles the original equations derived from 1960s studies, plus relevant results from later research, into a comprehensive set of equations to predict CO2 evolution and dry matter loss for corn stored at 15 to 35% moisture content (wet basis) and temperatures from 0 to 49³C. Effects of mechanical damage, genetic resistance to fungi, and fungicides are considered. A table of predicted shelled corn storage times for 0.5% dry matter loss and a table of multipliers for other dry matter loss levels are presented.
