Climate Nitrogen Monitoring Tool Support Trial

Trial Overview

  • Climate10;FieldView™ provides in-season field-level N monitoring based on fertility10;applications, crop stage, soil type, and weather. This tool can provide assistance to farmers to help with proper N management and nitrogen use efficiency (NUE).
 

Research Objective

  • This10;study was conducted to help build confidence in and validate the utility of10;Climate FieldView Nitrogen Monitoring Tool.

10; Site Notes:10;

10; Five locations across ND, NE, and SD.10; Irrigation was applied at the Bruning and Battle Creek, Nebraska10; locations.10;10; Two corn products were tested at each10; location. Total of 10 corn products ranging from a relative maturity of 8210; to 117. 10;10; Four N Treatments: *Check: No N applied *50 % N at planting + 50% N at growth10; stage V6.  *50 % N at planting + Nitrogen Monitoring10; insights at growth stage V6.  *100 % N at planting Nitrogen Monitoring Insights. The goal in10; using the Nitrogen Monitoring Tool was to determine how much N was needed10; and to adjust the rate so there was a surplus of 20 lbs of N available at10; black layer growth stage. 10;N amounts were determined based on the yield10; goal selected for the area – 1 lb N for 1 bu/acre. Soil type, previous10; crop, and tillage practice are all accounted for when determining the10; yield goal and the amount of N to apply at individual locations.10;

 

 

Understanding the Results

Figure 1.10;Yield response to nitrogen treatment across10;corn product relative maturities.
  • In this study, it was found that a split N10;application with half in the spring followed by a post application in-season10;when the crop is actively growing is more economical and efficient than10;applying 100% N at planting.
  • Using the Nitrogen Monitoring Tool in combination10;with a split application provided the highest NUE (1.30). 
  • Using the Nitrogen Monitoring insights versus10;just a 50/50 split application resulted in applying 15 lbs less N which10;resulted in saving $5.50/acre with a ROI of $13.50/acre. 
 

What Does This Mean for Your Farm

  • Results10;from this trial highlight the value that Climate FieldView Nitrogen Monitoring10;Tool provides growers for in-season monitoring and management of corn products.10;In this study, similar trends of NUE and cost savings were observed across10;locations (3 states) with different environments, reinforcing that Climate FieldView10;is a wise investment for producers.  
  • The Nitrogen Monitoring Tool is a reliable source10;for predicting N needs in corn to help obtain maximum yield potential and10;economic return while minimizing environmental impacts.
