Effects of Surface Applied N Sources on No Till Corn Yields

A four year Illinois study demonstrates how ESN can increase corn yields in no till, surface applied nitrogen systems. 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 long season demand.

In this four year study, ESN surface applied at planting to no till corn yielded higher than all treatments. ESN yields were 21 bu/ac higher than urea treatments.
