Other claims from this paper (17)
- Intervention effect Mulching reduced surface soil bulk density.
- Intervention effect Mulching increased soil porosity by 4.1–7.6%.
- Intervention effect Mulching increased meso and macroaggregates under wet sieving.
- Intervention effect Mulching increased meso and macroaggregates under dry sieving.
- Observation Under control, 69.5% of carbon was retained in microaggregates.
- Observation With plastic mulching, 47.8–56.7% of carbon moved to mesoaggregates.
- Intervention effect Plastic mulch maintained higher soil water content.
- Intervention effect Full plastic mulch improved surface 1.0 m soil water by 47 mm.
- Intervention effect Ridge–furrow mulch improved surface soil water by 26 mm.
- Intervention effect Biodegradable film mulch improved surface soil water by 20 mm.
- Intervention effect Full plastic mulch increased nine-year mean grain yield by 4784 kg ha−1.
- Intervention effect Biodegradable film mulch increased nine-year mean grain yield by 2413 kg ha−1.
- Observation Water use efficiency was 3.2 under full plastic mulch.
- Observation Water use efficiency was 2.8 under ridge–furrow mulch.
- Observation Water use efficiency was 2.7 under biodegradable film mulch.
- Observation Water use efficiency was 2.1 in the unmulched control.
- Recommendation Full-cover flat plastic film mulch appears viable for rainfed maize productivity in the Loess Plateau.
