**3.2 Carbon smart**

Total organic carbon is the amount of carbon related to living organisms or derived from them. Increasing carbon content in the soil may reduce atmospheric carbon dioxide and improve soil quality. Recent interests in carbon sequestration have raised many questions about how much carbon can be stored in the soil. The organic carbon content in soil can be improved through agricultural practices such as agroforestry, livestock, manure management, conservation tillage, diversified land use systems and residue management. As millet crop is grown on mostly marginal land with low organic matter (OM). Improving OM using different interventions can boost the pearl millet yields in Pakistan where soils of most areas are low in organic matter [31].
