- Observation The five-year mean maize grain yield without mulch was 3.8 Mg ha−1.
- Intervention effect Half mulch increased maize grain yield by 68% relative to no mulch.
- Intervention effect Full mulch increased maize grain yield by 102% relative to no mulch.
- Intervention effect Root biomass was 69% greater under half mulch than no mulch.
- Intervention effect Root biomass was 104% greater under full mulch than no mulch.
- Association Maize yield and biomass differed across years with growing-season precipitation and its distribution.
- Intervention effect Mulching increased maize yield and biomass consistently in all years.
- Intervention effect Mulch stimulated soil enzymatic activity.
- Intervention effect Mulch had no effect on light soil organic carbon concentration compared with no mulch.
- Mechanism Increased soil organic carbon mineralization under full mulch was offset by increased carbon addition.
- Intervention effect Full mulch increased maize productivity without detriment to soil organic carbon balance.
