Other claims from this paper (15)
- Intervention effect After six years, zero-till crop establishment had higher topsoil total organic carbon than conventional tillage.
- Intervention effect Zero-till crop establishment increased very-labile C fraction by 21%.
- Intervention effect Zero-till crop establishment increased labile C fraction by 16%.
- Intervention effect Zero-till crop establishment increased non-labile C fraction by 13%.
- Intervention effect Zero-till crop establishment increased less-labile C fraction by 7%.
- Intervention effect Conservation tillage had a higher passive carbon pool than CTTPR-CT.
- Intervention effect Zero-till treatments increased water-stable macro-aggregates, the macro-aggregate to micro-aggregate ratio, and aggregate carbon content over conventional tillage.
- Intervention effect The NPTPR-ZT effect was less prominent than the effects of ZTTPR-ZT and ZTDSR-ZT.
- Intervention effect Residue retention raised total organic carbon by 12% over residue removal.
- Intervention effect Residue retention raised available phosphorus by 16% over residue removal.
- Intervention effect Residue retention raised available potassium by 12% over residue removal.
- Intervention effect Residue retention raised DTPA-extractable zinc by 11% over residue removal.
- Intervention effect Residue retention raised available sulfur by 6% over residue removal.
- Intervention effect Conservation tillage and residue retention increased crop productivity relative to conventional tillage.
- Recommendation The authors recommend conservation tillage, particularly ZTTPR-ZT and ZTDSR-ZT, with crop residue retention for soil quality and production sustainability.
