What does the Season Chart display?
Below shows an example of what the Season Chart looks like with certain inputs and explains how those inputs impact the Season Chart.
- An account setup in Corteva Fields.
- Farm and Fields created.
- Crop assigned to a field.
- Yield goal set.
- Indicate the field's tiled status.
- Add nutrient products.
- Nitrogen plan template created and applied to a field.
The line on the season chart shows the estimated plant-available soil nitrogen throughout the growing season.
- Current weather conditions plus a short-term forecast are used to estimate soil nitrogen up to the current date + several days.
- Markers indicate management practices; for instance, you can see the impact on soil nitrogen of the fall application of 100 pounds of nitrogen as NH3 with an inhibitor.
- Estimated median soil nitrogen and a likely range (indicated by the shading) of potential outcomes for future dates is derived from multiple years of historical weather information. Changes in the slope of the line are due to various nitrogen dynamics such as crop uptake, weather losses, fertilizer applications, and mineralization gains.
- In this example, variable-rate nitrogen recommendations at approximately V6-8 growth stage brings the predicted nitrogen level up enough to meet the target nitrogen in each decision zone. The recommended rates for each decision zone are shown on the prescription map in the crop zone monitoring view.
