Description 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. The century irio
