- Intervention effect Cover crop mixtures had no advantages over monocultures.
- Intervention effect Cover crop mixtures increased fall stand density compared with monocultures.
- Intervention effect Rye and rye mixtures produced the greatest spring aboveground biomass (758 kg/ha) across environments, with the greatest C and N accumulation.
- Intervention effect Rye and rye mixtures had some of the lowest spring soil nitrate concentrations.
