Other claims from this paper (8)
- Intervention effect BC20 increased maize grain yield by 11.1% versus BC0.
- Intervention effect BC50 increased maize grain yield by 8.6% versus BC0.
- Intervention effect Biochar treatments reduced nitrous oxide emissions by 14.0%–19.5% versus CK.
- Intervention effect Biochar had no significant effect on field methane uptake.
- Observation Nitrogen fertilizer and biochar did not markedly change cumulative methane uptake over two years.
- Intervention effect Biochar lowered net greenhouse gas emissions by 16.7%–23.5%.
- Mechanism The authors attributed mitigation of nitrogen-fertilizer-related emissions to lower nitrogen oxide emissions and higher maize yield.
- Recommendation The authors recommend biochar as an economical strategy to mitigate emissions in rainfed maize cropping.
