Abstract

The effect of biochar amendment (2% and 10% on dry weight basis) and the biochar-soil contact period on the denitrification activity and methane oxidation in different type of soils was investigated. The result shows different soil responses to biochar amendments, that was attributed to the differences in soil properties. The N₂O production was lower without supplement treatments, and patterns were different from those observed with supplement treatments. Biochar does not seem to have a strong and consistent impact on denitrification or methane oxidation. Increased soil salinity or soil pH may have negatively affected microorganisms in sandy soil. Furthermore, the results show that the influence of two soil-biochar contact periods on denitrification or methane oxidation activities was not significant.
