Enhancing Carbon Sequestration Using Organic Amendments and Agricultural Practices

Carbon sequestration (CS) is an important strategy for the mitigation of climate change (CC) as well as for improving the soil fertility of agricultural soils. Carbon sequestration in crop lands and rangelands requires a certain amount of organic matter (OM) presence in the soil called soil organic matter (SOM). Organic amendments like animal and poultry manures, the incorporation of different crop residues, different types of compost, sugar - cane bagasse, peat soils, different wood chips, biochar and good agricultural practices like cover crops, nutrient management, mulching, zero and no-tillage techniques, soil biota management and mulching are effectively used for this purpose. These enhance the SOM and improve the soil’s physical and chemical properties which help to sequester more C in soil which ultimately contributes towards CS and CC mitigation. cover cropping, green manuring, crop rotations, agro-forestry, soil rehabilitation, reclamation and use of salt-affected soils for forest plantations and crop production.
