How much profit are you leaving in your fields?
Prescriptions for Variable Rate Application
By combining protein and yield maps, growers get a new look at their profit potentials. For instance, research from Montana State University has shown that hard red winter wheat with less than 12.5% protein is associated with nitrogen deficiency. A simple map of where the protein is higher or lower than 12.5%, combined with the yield map, can provide a prescription template for nitrogen application in upcoming years. Although weather and crop variety selection play major roles in protein production, nitrogen application is an input that producers can control and modify for their conditions.
Prescription maps can also be calculated using nitrogen removal algorithms or other locally created equations. Australian researchers with the CropScan 3300H data have developed analysis techniques to create three zone correlation and significance maps. This analysis helps growers understand which zones can benefit from additional nitrogen and which zones may have impact from other issues such as soil pH or moisture.

Knowing the quality of the crop finally allows producers to create meaningful profitability maps. When the crop income is based on quantity and quality, knowing yield just isn’t enough. Drill down into the data to really understand the profit and loss capabilities of different areas across the field.
On Farm Testing Analysis
The benefits of on farm fertility tests can be realized when quantity and quality information are combined. For instance, using strip trials, farmers can do their own testing of nutrient applications, or determine if straight rate fertility is as profitable as variable rate fertility.
