Avoid false either-or claims
Seed is not a pesticide. A cover crop may suppress weeds, influence nutrient supply or interrupt a pest cycle, but each effect depends on establishment, target species and timing.
Use a substitution test
Before reducing an input, define the function it performs and the evidence that the cover crop can provide that function.
- Identify the target weed, nematode or nutrient need.
- Set a threshold and monitoring method.
- Run a managed strip or field comparison.
- Keep a rescue option during transition.
Make claims at the right scale
Report the crop, soil, climate, rate and comparator. Do not turn a trial result into a universal promise.
