Other claims from this paper (11)
- Observation Bare-soil methane flux varied between 0.04 and 0.93 mg m(-2) hr(-1).
- Intervention effect Transplanting rice doubled methane flux relative to bare soil (0.07 to 2.06 mg m(-2) hr(-1)).
- Intervention effect Pusa 44 emitted significantly more methane than PR 118 and PR 111.
- Intervention effect Application of organic materials enhanced methane emission from rice fields.
- Intervention effect Wheat straw amended plots had the greatest seasonal methane flux (229.6 kg ha(-1)), compared with control (21.5 kg ha(-1)).
- Intervention effect Farmyard manure gave a higher seasonal methane flux (111.6 kg ha(-1)) than control (21.5 kg ha(-1)).
- Intervention effect Green manure gave a higher seasonal methane flux (85.4 kg ha(-1)) than control (21.5 kg ha(-1)).
- Intervention effect Rice straw compost amended plots had the least seasonal methane flux among the amendments (36.9 kg ha(-1)), but more than control (21.5 kg ha(-1)).
- Recommendation Incorporating humified organic matter such as rice straw compost could minimize methane emission from rice fields.
- Intervention effect Incorporating humified organic matter such as rice straw compost is associated with co-benefits of increased soil fertility and crop productivity.
- Association The differential effect of organic materials on methane flux was related to total carbon or C:N ratio of the material.
