Use of biochar as soil amendment and its impact on GHG reduction has not been tested in Latvian climate conditions. Application of biochar to soil can reduce N2O emissions by up to 80% and eliminate CH4 emissions, which both are more potent greenhouse gases than CO2. The biochar can sequester carbon in the soil for hundred to tousands of years, like coal. In addition to carbon sequestration, biochar improves the soil (fertility, resistance to erosion, etc.), thus bringing economic benefits for the farmer.
