Utilizing Climate Fieldview™ Nitrogen Monitoring Tool

Trial Overview

13;10;
  • Nitrogen (N) is the most vital fertilizer that farmers have to manage in a corn crop. 
  • 13;10;
  • Previous crop, growing conditions, product genetics, commodity price, and N cost are factors to consider when determining the highest return for N investment.
  • 13;10;
  • Weather plays an important role in determining how growers manage N. Programs like Climate FieldView™ nitrogen monitoring tool can help farmers in their N decision making process.

Site Notes:

13;10;
A study was established to help understand how Climate FieldView nitrogen monitoring tool can help corn farmers make N decisions on their farm.Six different N application treatments were applied to corn products with two replications.
 
13;10;
       -- Treatment 1: 200 lbs N/acre (32% UAN) applied preplant on May 6,2016. 
 
13;10;
       -- Treatment 2:  170 lbs N/acre (32% UAN) applied preplant on May 6, 2016 + 30 lbs N/acre applied pretassel to tassel on July 5, 2016. 
13;10;
       -- Treatment 3: 200 lbs N/acre (32% UAN) applied preplant on May 6,2016 + the Climate FieldView nitrogen monitoring tool recommended rate applied at pre-tassel to tassel (Climate FieldView showed a surplus of N at time of application so no additional N was applied)
 
13;10;   -- Treatment 4: 100 lbs N/acre (32% UAN) applied preplant + 100 lbs N/acre (32% UAN) sidedressed on June 14, 2016. 
 
13;10;   -- Treatment 5: 100 lbs N/acre (32% UAN) applied preplant + 45 lbs N/acre (32% UAN) sidedressed on June 14, 2016 (Climate FieldView nitrogen monitoring tool sidedress recommended rate) 
 
13;10;   -- Treatment 6: 170 lbs N/acre (32% UAN) applied preplant + Climate FieldView nitrogen monitoring tool recommended rate for sidedress or late application, no applications recommended. Cost and net profit is based on N cost of $0.50/lb, sidedress cost of $8/acre, corn price of $3.20/bushel.

Understanding the Results

13;10;
  • The highest yielding treatment was not a recommendation from Climate FieldView nitrogen monitoring tool. However, the most profitable N treatment was from a Climate FieldView insight. 
  • 13;10;
  • The most profitable application did not require N to be applied during the growing season, saving time and input cost by using Climate FieldView nitrogen monitoring tool. 
  • 13;10;
  • Two of the three nitrogen treatments that were Climate FieldView insights still reached a high yield and had the most profitability.
13;10;

What Does This Mean for Your Farm

13;10;
  • Climate FieldView nitrogen monitoring tool provided the most profitable treatment in this trial.
  • 13;10;
  • Climate FieldView nitrogen monitoring tool will continue to be analyzed to see how the program can benefit farmers with preplant and in-season N application decisions.
