e5“the near-saturation strategy resulted in a 17.3% reduction (CF: 23.32 Mg CO 2 -eq ha −1 vs. water-saving: 19.28 Mg CO 2 -eq ha −1 ) in the net ecosystem C source strength (net GHG emissions minus soil organic C sequestration) through the substantial CH 4 mitigation over the two-year period”

Other claims from this paper (6)
- Intervention effect Near-saturation irrigation reduced cumulative CH4 emissions by approximately 29% compared with continuous flooding in organic double-rice in Taiwan.
- Intervention effect Near-saturation irrigation reduced net GHG intensity from 1.37 to 0.97 Mg CO2-eq per Mg grain compared with continuous flooding in organic double-rice in Taiwan.
- Intervention effect Near-saturation irrigation maintained stable grain yield (about 5.24 Mg/ha) compared with continuous flooding in organic double-rice.
- Intervention effect Near-saturation management improved irrigation water productivity by 16.5% in organic double-rice.
- Mechanism Reduced CH4 emission through near-saturation management explains the lower net ecosystem C source strength of organic double-rice.
- Intervention effect Winter cover crop incorporation did not significantly change GHG dynamics or crop productivity.
