Emission of carbon dioxide from soil

Carbon dioxide (CO2) is an important greenhouse gas accounting for 60% of the total greenhouse effect. Soil is a major source for atmospheric CO2. In the event of growing threats of global warming due to greenhouse gas emissions, reducing CO2 emission by sequestering C in the soil is of prime importance. Soil management practices like increasing soil organic carbon content, reduced tillage, manuring, residue incorporation, improving soil biodiversity, micro-aggregation and mulching can play an important role in sequestering C in soil.
