Nitrogen Watch 2017

This page tracks 2017 spring rainfall and identifies ‘danger areas’ that are on track to have problems with N loss and deficiency in corn.  This is a serious production and environmental problem that I estimate cost Midwestern corn producers 2 billion bushels total from 2008 to 2011.
