Managing Your Nitrogen With Variable Rate Population

July 28, 2014
p38 The Challenge of Nitrogen 1

During one of this year’s Farm Journal Corn College hands on "In the Field Diagnostics" breakout sessions in Heyworth, Illinois, Bill Bauer of B&M Crop Consulting discusses the importance of early diagnosis in your corn fields.

In this segment, Bauer demonstrates how population interacts with nitrogen management. He warns that when the grower goes to variable rate populations without properly adjusting the nitrogen along with those rates, then you could be going backwards and hurt your yields. 

Watch the full Corn College Field Diagnostics series with Bill Bauer on the Corn College channel.

This year farmers also learned how to use NDVI maps and GPS on Ipads to help locate different locations in a corn field and diagnois what "problems" were occurring at that location.

Each location had "good zones" and "poor zones" where participants were asked to go through these 6 steps when diagnosing crop condition.

1. Do a visual inspection(plant development, uniformity)

2. What does the stand look like ( population, stand and ear count)

3. Root development and soil density layers

4. Soil assessment- (compaction, slope, soil health residue)

5. Dissect the plants ( stalks and leaves)

6. Collect samples and analyze(soil test, tissue test, nitrate)
