What soil depth is used in the Nitrogen model?
Requirements:
- Corteva Connection Establish (If wanting to push/pull zones)
- Roles and Permissions set
- Invoice Granular Agronomy through Connex
- Fields are in Insights
- Crops Assigned in Activities
- Decision Zones Created or Synced from Corteva
- Field Details Set
- Add New Nitrogen or Planting Events
Answer:
The Granular Crop Model tracks nitrogen dynamics in the top 2 meters of soil. The Season Chart display and nitrogen recommendations are based on the set modeling depth.
- Depth can be selected in the web interface in 6-inch to 1-foot increments.
- The depth range summarizes and reports the data for the set depth.
- Think about the typical effective rooting depth for the soils in your field.
- Two feet is appropriate for most soils in the Midwest Corn Belt.
- Shallow soils, especially with restrictive layers or shallow water tables, might benefit from using a 1-foot reporting depth.
- Extremely well-drained soils with deep rooting potential might benefit from using 3-5 feet reporting depths.
