A University of Nebraska study shows that ESN is an important component of high-yield, intensively managed corn production. The study evaluated ESN in combination with high plant populations and narrow row spacing, practices shown to increase yields under intensive management.
Typical nitrogen (N) Best Management Practices recommend side-dressing or split applications of conventional N fertilizers. This practice can be difficult or impossible with narrow row spacing. ESN’s controlled-release of N allows the grower to apply N before planting and eliminates the need to side-dress.
Comparison of N source, row spacing and plant population combinations for high-yield irrigated corn in Eastern Nebraska. All N treatments applied at 179 lbs N/acre. For the split ammonium nitrate treatment 50% of N was applied before planting, 25% at V8 and 25% at VT. Source: A. Doberman and D. Walters of Univ of Nebraska.
