Nitrogen treatments broadcast as ESN at indicated time at 100 lbs N/acre. Studies conducted at multiple locations in Illinois. Yield increases are means of nine site-years. Source: Dr. F. Below, Univ of Illinois. Recommended N rates as ESN are approximately 40-80 lbs N/acre depending on yield potential, N supplying capacity of the soil, and ESN and soybean prices.
A multi-year Illinois study demonstrates how ESN can increase yields in high-yield soybean production. ESN can provide additional nitrogen to soybean plants during flowering and pod set, resulting in higher yields. 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 soybean yields and improved N-use efficiency.
Soybean plants need N throughout the growing season. Most N needed by the plant is produced through nodules on the roots, however, under high yield situations, naturally fixed N may not be sufficient for top yields. Using ESN, additional N can be supplied to meet peak N demand without interfering with the natural N-fixing mechanisms of the root nodules.
ESN increased yields over nine site-years by almost five bu/acre.
Applications anytime from planting until bloom significantly increased soybean yield.
ESN increased soybean profits by over $10 per acre at recommended ESN rates and typical soybean and ESN prices.
