Other claims from this paper (7)
- Observation Soil total N concentration varied by sampling time and decreased with depth.
- Intervention effect Soil N at 0 to 90 cm was greater with vetch or vetch plus rye and N than weeds in no-till and chisel-till.
- Intervention effect Soil N at 0 to 30 cm was greater with vetch or mixed cover crop than weeds in strip tillage.
- Intervention effect No-till and chisel-till N storage gained 71 to 108 kg N ha −1 yr −1 with vetch or mixed cover crops and N.
- Intervention effect Strip-till N storage gained 101 to 103 kg N ha −1 yr −1 with vetch or mixed cover crops.
- Intervention effect Legume or mixed cover crops increased soil nitrogen storage compared with no cover crop.
- Recommendation The authors propose replacing legume cover crop with biculture and reducing N fertilization.
