VRN

Variable Rate Nitrogen

Increase Yield   and

Reduce Nitrogen Cost

Why Variable Rate Nitrogen? (VRN)

The first limiting fertilizer nutrient to increasing  corn yield is Nitrogen.

The most expensive fertilizer nutrient is Nitrogen.

Excess Nitrogen becomes pollution, a shortage of Nitrogen reduces yield.

 

VRN is the only tool there is today to match nitrogen rate with yield potential.

 

Variable Rate Nitrogen Data Required

Data Needed

• Field Location, Border
• Crop Rotation (last 3 years)
• Field Average Corn Yield
• Yield Goal for 2003
• Field Organic Matter (%

 

Why use the same Nitrogen rate on soils that yield at different rates???

 

 

VRN Product for Corn

Features

•  Reduce N application                  
•  Increase yields 
•  Lower Cost
• Reduce N runoff (pollution)

 

 

** THE INVESTMENT **

$10 per acre

 

THE RETURN

Nitrogen Savings = $10 to $26 per acre

Improved Yields  

Improved Environment
