Impact of Agricultural Practices and their Management Techniques on Soil Carbon Sequestration: A Review

Abstract

Carbon emissions through various sources possess a great threat to the environment. An increase in carbon concentration in the atmosphere resulted in increased temperature. Escalating warmness in the environment started melting of glaciers, day by day water level in oceans also increasing at an alarming rate. Forests, oceans and agricultural soils act as a sink for atmospheric carbon. Sinking sites help in making the balance of various gases in the atmosphere. Managing agricultural soils provides a good opportunity for more carbon storage. Adoption of conservation tillage, incorporation or on surface management of crop residue and balanced fertilization helps in reducing carbon removal from soil. More organic matter means more humus formation and more carbon retention in soil. Such management practices not only boost soil carbon-storing capacity but also increase soil fertility through hiking nutrient availability to plants and microbial populations in the soil. Higher plant growth results in more assimilation of CO2 in the photosynthesis process.
