- Intervention effect Conservation tillage increased carbon input relative to conventional tillage.
- Intervention effect Conservation tillage reduced carbon loss by stover burning or removal.
- Intervention effect Conservation tillage reduced carbon loss by soil erosion.
- Observation Energy inputs ranked CT above RT above NT.
- Observation Carbon emissions ranked CT above RT above NT.
- Intervention effect No till and reduced tillage reduced embodied energy consumption by 4–12%.
- Intervention effect Conservation tillage decreased the coefficient of energy consumption by 6–10%.
- Intervention effect Conservation tillage increased the coefficient of energy production by 7–12%.
- Observation Soil organic carbon sequestration changed from -104 under CT to 144–149 under NT and RT.
- Observation No till soil respiration was highest at the maize growth peak.
- Observation Total soil respiration ranked RT above NT above CT.
- Observation Maize grain yield ranked RT above NT above CT.
- Association Maize grain yield was positively associated with soil respiration during growth.
- Recommendation The authors conclude that stover incorporation with conservation tillage enhances soil organic carbon.
