Résumé
Carbon sequestration is known to the potential win -win strategy, as it is an option to mitigate the climate change as well as the solution to soil degradation probicm by decreasing the Cconcentration in atmosphere and increasing the organic carbon in soil and which in turn increase soil fertility. This report explains the need of Carbon sequestration focusing on semi arid regions. It describes different niut,agi,iiieni practices, and cropping pattern which increase the carbon sequestration porennui tn soil. These practices are found to be : no tillage, crop residue uppiicahon. oryami manure addition, crop rotation, fallowing and stubble grazing etc. A simulation study was also conducted for Kothapally uiilugr, undrr rifii’ri.iit management practices (referred as 8 scenarios in the report) and best i u  u g e n c n t practices was idenn3ed. The results were also extrapolatedfor Kolhupally to absesa thr effects of managementpractice and cropping pattern. The crop and the duration for which model has simulated was Pigeonpea and 30 years respectiueiy. The model used was CENTURY model (version 5) initially deueloped by W J Parton et al. (198 :) for temperate regions. The result of simulation study has shown that there is a significant increase 111 SOC from initial tofinal SOC under 4 scenarios : no tillage practice, lnu’ interisity gruiliny, double organic manure addition (including vermicompost) suhshtutiny inorqa iir fertilizer and the fourth scenario include all the improued practices.
