Abstract

Seed and nitrogen are among the leading costs of corn production. As variable-rate technology becomes more available to growers, they need a clear understanding on how to utilize these technologies. The objective of this LIVE plot project is to determine the effects of nitrogen and seeding rate on corn productivity and profitability as a function of cation exchange capacity (CEC). This program will inform producers with precision application technologies how to adjust seeding and nitrogen fertility rates as function of CEC to optimize corn grain yield and on farm profitability.
