Biochar amendments influenced the NH3 volatilization in rice paddy soils. The floodwater and surface soil of biochar treatments recorded higher pH value. Lower nitrogen nitrification rate was found in biochar treatments. Biochar should be applied at a lower rate to the rice paddy soil, considering the NH3 volatilization.
