Surface Applied Nitrogen Sources on Conventional-Till Corn Yields

A multi-year Illinois study demonstrates how ESN can increase corn yields in conventional tillage corn production. ESN protects nitrogen (N) from loss inside its unique protective coating and supplies N to the crop when it is needed. The result is increased corn yields and improved N-use efficiency.

Corn plants need N throughout the growing season. Most N uptake by a corn plant takes place in the period of about 40-80 days after planting and continues up to 120 days after planting. ESN may be used to meet this season-long demand.

In this study under conditions conducive to N loss, ESN produced greater yields than other nitrogen fertilizers, including other enhanced-efficiency materials.
