In this Texas study, ESN applied to the surface of the soil at lay-by yielded more than UAN solution injected into the soil. A study conducted by Dr. Archie Abrameit, Texas A&M, Thrall, TX. ESN applied on 4-29 and UAN applied on 5-1 both at a rate of 70 pounds N/acre.
A Texas study demonstrates how ESN can increase yields in dryland cotton 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 cotton yields and improved N-use efficiency.
Cotton plants need N throughout the growing season. Most N uptake by a cotton plant takes place in the period of about 40-80 days after planting and continues up to 140 days after planting. ESN may be used to meet this long-season demand.
