Last summer I provided observations in three ICM News articles (June 19, June 26, and July 8, 2008) on corn growth and response to nitrogen (N) applied in an anhydrous ammonia study conducted at the Iowa State University research farm between Ames and Boone. This series of articles was written in response to the record wet conditions encountered in 2008. Following is a summary of the grain yield response to N timing and rate.
