Nitrogen Watch 2018

This page tracks 2018 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.

Nitrogen watch for well- and moderately well-drained soils:
