Select the Right Time for nitrogen application.
Apply the Right Rate of fertilizer to meet crop needs.
Costs of inputs make it important to provide enough N so the crop is never deficient. For greatest efficiency, N should be applied close to the time it will be used by the crop.
This demonstration compares 3 different application times:
- Fall Application
- Spring Application
- Split Application---½ applied in Fall and ½ applied in Spring
A second demonstration compares the full recommended N rate with a reduced rate (85% of recommended rate) using a controlled-release source, ESN®.
ESN® controlled-release technology delivers N to the crop all season long, not just when it's applied, allowing the crop to reach full genetic potential. The unique polymer coating helps prevent against all forms of N loss, including volatilization, denitrification, and leaching.
When used correctly, ESN® can substantially reduce N losses to surface water, subsurface drainage water, and groundwater, a positive impact to water quality.
