Soil carbon

Increasing soil organic carbon (SOC) is widely regarded as beneficial to soil function and fertility and has been associated with increased agricultural productivity. With soil being considered a major world carbon sink (as well as a source of carbon emissions), increasing the amount of organic carbon in agricultural and rangeland soils is seen as one way of mitigating climate change. Consequently there is great interest in quantifying the ability of various soil types and land management practices to increase net organic carbon inputs. Research undertaken at the Department of Agriculture and Food, Western Australia is contributing to this work by establishing an evidence base on soil, climate and management factors influencing soil organic carbon and related production outcomes.
