Other claims from this paper (10)
- Intervention effect Ground cover rice production increased soil organic carbon stocks relative to paddy fields.
- Intervention effect Ground cover rice production increased soil nitrogen stocks.
- Intervention effect Soil physical and chemical properties mostly did not differ between production systems.
- Intervention effect Soil bulk density was an exception to the otherwise unchanged soil properties.
- Intervention effect Ground cover rice production lowered soil organic carbon mineralization potential.
- Intervention effect Ground cover rice production lowered leaf δ15N.
- Mechanism Lower δ15N indicated less ammonia volatilization under ground cover production.
- Intervention effect Ground cover rice production increased yields.
- Intervention effect Ground cover rice production increased root biomass through 40 cm soil depth.
- Recommendation The authors recommend ground cover rice production as a water-saving, yield-raising technique with higher soil carbon and nitrogen stocks.
