- Intervention effect These systems could not maintain soil carbon or nitrogen without compost.
- Intervention effect Alley cropping, organic management, conservation tillage and compost maintained soil carbon.
- Intervention effect Those systems increased soil carbon when mulch was omitted.
- Intervention effect Under organic conservation tillage without alley cropping, soil carbon did not change significantly despite annual compost.
- Observation Soil nitrogen followed the same patterns as soil carbon.
- Intervention effect Alley cropping maintained and sequestered more soil carbon and nitrogen than organic conservation tillage alone or conventional management.
- Intervention effect Crop yields did not vary by treatment amid high within-treatment variation.
- Intervention effect Winter cover crop residue suppressed weeds for 4 to 6 weeks in spring.
- Recommendation Additional hand weeding remained necessary throughout summer.
