Soil carbon density in Kg m-2

Soil Organic Carbon stock – 22.7 Pg

Soil Inorganic Carbon stock -12.8 Pg

TOTAL SOIL CARBON DENSITY

Information on Soil Carbon density will be useful in prioritizing areas for soil carbon sequestration in different agro-climatic regions as well as for effective soil carbon management to reduceCO2 emissions from soils.
