Cotton Response to Pre Plant Incorporated Urea and Environmentally Smart Nitrogen in a Representative Arkansas Silt Loam

In 2016, approximately 375,000 acres of cotton were harvested in Arkansas. Supplemental N fertilization is required to produce economically sustainable cotton yields. Improving N use efficiency by reducing fertilizer-N losses to the environment will increase profit margins and reduce potential environmental risks associated with N fertilization.  Replicated field experiments were conducted at four locations on soils typically used for cotton production in the delta region of Arkansas to evaluate cotton response to urea and an enhanced efficiency N fertilizer (ESN).
