Other claims from this paper (16)
- Intervention effect Plastic film mulching raised maize yield by 26.8%− 73.4% versus conventional tillage.
- Intervention effect Plastic film mulching raised yield sustainability index by 4.4%− 13.9%.
- Intervention effect Plastic film mulching reduced maize yield variation by 0.7%− 10.7%.
- Observation Average change in soil water storage was positive for every tillage pattern.
- Observation Rainwater use potential reached 88.3–96.9%.
- Observation Nitrogen budgets were positive with nitrogen input and negative without it.
- Intervention effect Plastic film mulching exacerbated nitrogen consumption without nitrogen application.
- Intervention effect Straw mulching mitigated nitrogen consumption without nitrogen input.
- Intervention effect Plastic film mulching maintained soil total nitrogen and organic carbon.
- Intervention effect Straw mulching raised soil total nitrogen by 27.1–29.8%.
- Intervention effect Straw mulching raised soil organic carbon by 22.3–33.3%.
- Intervention effect Straw mulching produced variable yield, especially without nitrogen.
- Intervention effect Ridge tillage yielded only a small increase and a higher coefficient of variation.
- Intervention effect Ridge tillage increased yield coefficient of variation.
- Intervention effect Ridge tillage lowered yield sustainability index.
- Recommendation The authors recommend plastic film mulching to stabilize maize yield and improve soil resources.
