Other claims from this paper (6)
- Intervention effect Biochar increased soil pH in both years.
- Intervention effect Biochar at 10 t ha-1 reduced rice grain Cd concentration by 16.8% in 2009 and 42.7% in 2010.
- Intervention effect Biochar at 20 t ha-1 reduced rice grain Cd concentration by 37.1% in 2009 and 39.9% in 2010.
- Intervention effect Biochar at 40 t ha-1 reduced rice grain Cd concentration by 45.0% in 2009 and 61.9% in 2010.
- Intervention effect Total plant Cd uptake decreased under the three biochar rates in both years.
- Recommendation Biochar combined with low Cd cultivars may reduce Cd levels in rice and greenhouse gas emissions.
