University research and extension are critical in equipping producers and agronomists with the information they need to continue advancing corn production in Iowa. Incorporating new scientific findings and recommendations into today's agricultural systems must be our priority to consistently produce a high quality crop that is also economically feasible.
Corn Quality Issues in 2008
Charlie Hurburgh, Roger Elmore, and Alison Robertson
Iowa grain yields are predicted to be third highest in state history (USDA October estimate of 172 bu/acre); however, grain quality may be poor in areas. A cool, long, growing season can result in high yields with high grain moistures and low test weights. High grain moisture paired with our fall conditions can also favor the development of fusarium fungi, which can produce several toxins harmful to people and livestock such as vomitoxin, zearalenone, and fumonisin. Livestock (swine, cattle, horses, and poultry) are susceptible to certain mycotoxins. Grain management and storage will be particularly important this year. A three-part series of articles address issues related to storage management and practical steps to maintain grain quality. Read On
