The study looked at how different crops and fertilization methods affect the amount of carbon stored in the soil. They found that perennial super napier fodder led to the highest increase in carbon buildup, followed by maize intercropped with pigeonpea and sunhemp. Overall, all cropping systems showed an increase in total organic carbon. Only a small percentage of the carbon added to the soil was stabilized as soil organic carbon. To maintain soil organic carbon levels, a minimal input of carbon is needed each year. Perennial super napier fodder had the highest carbon management index and required the least amount of money to sequester carbon in the soil.
