Soils
Biochar application to agriculture soil has been recommended as a strategy to reduce increasing atmospheric carbon dioxide (CO2) concentrations and mitigate climate change. Significant suppression of soil CO2 emissions following biochar amendments has been demonstrated in short-term laboratory incubations by several authors, yet evidence from long-term field trials has been contradictory. This study investigates whether biochar addition to the soil could suppress soil CO2 emission under field conditions after 6–th years following amendment. CO2 emissions were not significantly suppressed with biochar addition, although they were generally low. Biochar amendment suppressed soil cumulative CO2 emissions by 30.59%. These findings demonstrate that biochar amendment has the potential to suppress soil CO2 emissions in corn crop system after 6–th years of biochar application. We conclude that the concentration of soil CO2 emissions were depended on soil temperature measured during study period.
