Other claims from this paper (5)
- Intervention effect Cover crops reduced fall soil nitrate-N versus no cover crops when cover crop growth was good.
- Intervention effect Cover crops did not negatively influence cash crop yields in fall 2016 or 2017.
- Recommendation The authors recommend choosing soil health sampling time according to sampling goals.
- Recommendation For finding cover crop differences with ample spring biomass, sampling corn at V3-V6 may be best.
- Recommendation To detect the highest seasonal soil indicator values, sampling after harvest may be best.
