Variable Rate Nitrogen Application

311

Situation:

Growers can use TerrAvion imagery to identify fertility issues in their fields and to make targeted variable rate fertilizer applications. In this example, the grower identified a low vigor area in the June 27 imagery, which alerted him to a nitrogen deficiency. Having quantified the nitrogen-deficient areas, the grower decided to make a variable rate nitrogen application, targeting the deficient areas with a higher rate. The September 11 imagery shows that the nitrogen application was successful in creating uniform growth throughout the field two and a half months later.

Action:

Use TerrAvion aerial imagery to identify low vigor zones, which may be caused by fertility problems. Take corrective action to avoid potential yield losses before it is too late.
