Sensing Nitrogen Stress In Corn, John E. Sawyer, John Lundvall, Jennifer S. Hawkins, Daniel W. Barker

Agriculture and Environment Extension Publications

Determining the proper nitrogen (N) fertilization rate is important for the economic viability of corn production. A desire for high yields, fueled by low fertilizer N costs, led producers to apply rates that ensured adequate N rather than risk costly yield losses due to a shortage of N. Due to water quality concerns and recently high N fertilizer prices, management strategies are needed that can improve the efficiency and profitability of N use. With N application rates based on economic return instead of maximizing productivity, producers want to confirm that rate decisions are working adequately. Also, if unexpected N losses ...

Grain Test Weight Deception, Carl J. Bern, Thomas J. Brumm Oct 2009

Grain Test Weight Deception, Carl J. Bern, Thomas J. Brumm

Agriculture and Environment Extension Publications

Test weight is used as an indicator of general grain quality and is a measure of grain bulk density. Test weight, but not overall grain weight, normally increases during drying. Erroneous calculations using test weights can incorrectly infer that drying systems that increase test weight also increase the number of bushels that can be sold. This bulletin explains the use of test weight in the grain industry, how it can be used to determine grain value, and why some calculations involving test weight can be deceptive.
