Here's the soil nitrate map you've been waiting for


From good Big Show Buddy Mike Castellano at Iowa State, as we know from 2012 after a dry growing season or a drought growing season there is more nitrogen left over in the soil meaning we need to adjust production practices and applications accordingly. Iowa State University predicted soil nitrate levels as of September 2021. Updates will be posted shortly here, and you can see the most recent map simply by clicking below.
