A two year Missouri study demonstrates how ESN can increase protein levels in corn. 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 protein.
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 two year study averaged across five corn hybrids, ESN surface applied at planting to no till corn increased protein levels compared to urea and the untreated check. Protein levels in ESN treatments were slightly lower than those in the anhydrous ammonia treatments.
