Abstract

The Iowa nitrogen (N) response database in the corn nitrogen rate calculatorwas recently updated, with response trials added from 2009 research. There are now 188 trials for corn following soybean and 89 trials for corn following corn. Being able to easily update the database with recent data is one of the many advantages to this dynamic database approach for corn N rate guidelines. Having new response trial data allows rapid updating with changing hybrid genetics, rotations and climatic conditions.
