An Arkansas study demonstrates how ESN can increase yields in irrigated 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 long season demand.
In this Arkansas study, ESN applied pre-plant yielded higher than urea applied pre-plant or in a split application for each N rate evaluated. When the addition of an at tassel application of urea was made in combination to ESN pre-plant, yields were not affected when averaged across rates.
