Are cover crops included in the Nitrogen model?
Overview:
Discussion of cover crops in the Nitrogen model.
Requirements:
- 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.
Answer:
No. We currently do not have adequate data available to calibrate the Nitrogen model to accurately account for the widely ranging situations presented by cover crops. There are many different species used as cover crops, they are killed at various stages, and the stand density can vary tremendously between growers, fields, and within fields. Cover crop composition (carbon pools and nitrogen percentage) and dry matter quantity change, not just by species, but over time within a species (think early spring to late spring). This makes the process of modeling the effects of cover crops in the model challenging. This is a future opportunity for model improvements.
