FieldView™ Nitrogen Management Recommendations

Trial Overview

  • Nitrogen (N) is the number one fertilizer that farmers must manage in a corn crop.
  • Previous crop, growing conditions, product genetics, commodity price, and N cost are factors to consider when determining the highest return for N investment.
  • Weather plays an important role in how farmers manage N. 

Research Objective

  • To help determine how FieldView™ nitrogen management recommendations can help farmers manage N.

Site Notes:

Five 32% UAN N Treatments Consisting of Three Replications
       - Treatment 1: 200 lbs/acre 32% UAN applied Pre-Plant on 5/9/17 = Standard Rate (SR)
       - Treatment 2: SR-15% or 170 lbs/acre followed by (fb) 30 lbs/acre applied 2 weeks pre-tassel on 7/5/17
       - Treatment 3: SR-15% fb a FieldView nitrogen management recommendation of 35 lbs/acre applied 2 weeks pre-tassel to tassel
         on 7/5/17 (Figure 2, Top)
       - Treatment 4: Half SR fb 100 lbs/acre applied by sidedress on 6/19/17
       - Treatment 5: Half SR fb a FieldView nitrogen management recommendation sidedress rate of 75 lbs/acre on 6/9/17
         (Figure 2, Bottom).       

Understanding the Results

 
Figure 1. Average yield and net income/acre after nitrogen cost for five different nitrogen application treatments at Monmouth, IL in 2017 (3 Replications)
  • Yields were good across the five treatments (Figure 1); however, FieldView nitrogen management recommendations provided a higher gross profit/acre and the highest yielding treatment (Figure 1).
  • The Monsanto Learning Center at Monmouth, IL will continue to examine ways FieldView nitrogen management recommendations can provide farmers with information to help manage N and in-season N application decisions.

What Does This Mean for Your Farm

  • When used by farmers, FieldView™ nitrogen management recommendations can provide valuable information that can potentially increase yields and net income. 
  • Yields were good across the five treatments; however, FieldView nitrogen management recommendations provided a higher gross net income/acre and the highest yielding treatment.
  • Because of the advantage that FieldView nitrogen management recommendations provide over other online N management calculators, farmers can react quickly to changing weather patterns.
