Adjusting Nitrogen Inputs

It's not enough to vary plant populations across your fields; you need to adjust your input schedule as well. In this video from Farm Journal's Corn College, 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. 

Farmers can also use NDVI maps and GPS on iPads to help locate different locations in a corn field and diagnose what problems are occurring at that location.

Farmers should 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)
