The Effect of different agronomic management practices to increase carbon sequestration in rice based cropping system

A LITTLE REVIEW

Abstract

The dramatic increase in atmospheric CO₂ concentrations and the loss of soil organic carbon (SOC) have sparked interest in using soil as a carbon sink [1]. Soil carbon has been lost due to poor soil and crop management techniques. Around 1417 Pg of soil carbon is stored in the first metre of soil depth around the world, while 456 Pg is stored in above-ground vegetation and decaying organic matter. Healthy soils will aid in the fight against global warming since soils with high organic matter have a higher CO₂ sequestration potential. Agriculture accounts for roughly 25-30% of total global GHG emissions in the form of CO₂, NO₂, and CH₄. Rice-wheat, an intense and dominant cropping system that covers 24 million hectares of tilth worldwide, contributes greatly to global warming potential. Adapting suitable tillage procedures, using quiet crop rotations to build soil organic matter, and adding organic fertilisers are all examples of agronomic management methods that can help with soil carbon sequestration [2]. As a result, the goal of this study is to identify the most effective management techniques for C sequestration in the rice-wheat cropping system by increasing SOC.
