Effects of ESN on Cotton Yields in Southwest Georgia

A study conducted by Dr. Ron Sorenson, USDA-ARS, Shellman, GA. ESN and 28-0-0-5 was applied at lay-by.

A Georgia study demonstrates how ESN can increase yields in irrigated 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.

In this Georgia study, ESN applied to the surface of the soil at lay-by yielded higher than UAN solution injected into the soil.
