ESN Top-Dressing in Corn: More Flexibility, Less Crop Burn, Less N Loss

ESN Is An Excellent Option For Applying Your Entire Nitrogen (N) Needs Pre-Plant, But Don’t Forget The Benefits Of Top- Dressing ESN.

Why Top-Dress With ESN?

  • ESN’s coating minimizes N loss, releasing N when the crop needs it.
  • ESN has a wider window of application than conventional N sources.
  • ESN is faster to apply than ammonia or solution.
  • ESN can be applied under conditions not suitable for other N sources.
  • ESN will not burn the crop like urea or ammonium nitrate.

ESN Top-Dress Recommendations

Northern Geographies (North of I-80)

  • For maximum benefit, apply at or before V4 stage.
  • Broadcast is acceptable where surface movement is minimal and soil moisture is at acceptable levels; incorporation is encouraged.
  • ESN recommended at 50-75% of N requirements.

ESN Top Dress Recommendations

Southern Geographies (South of I-80)

  • For maximum benefit, apply at or before V4-V6 stage.
  • Broadcast is acceptable where surface movement is minimal and soil moisture is at acceptable levels; incorporation is encouraged
  • ESN recommended at 60-80% of N requirements
Top-Dressing Corn with ESN Provides Greater Application Flexibility, Reduces Crop Burn And Protects Your N From Loss
Corn yields are the average of four years. Treatments were applied at 150 lbs N/acre broadcast without incorporation. Source: Dr. K. Nelson, Univ. of Missouri.
