Studies on Soil Organic Carbon Status of Agastheeswaram Taluk - A Survey

The soil body is the largest terrestrial pool of organic carbon globally. Soil Organic Carbon (SOC) believed to play a crucial role for many soil functions and eco systems services. The changes in SOC are largely determined by how much biomass is grown and retained above and below ground. As indicator for soil health, SOC is important for its contribution to food production mitigation and adaptation to climate change and the achievement of the sustainable development goals. To achieve greater specificity and accuracy, improved methods are required to measure, account, monitor and report on this specific carbon pool. Walkely and Black titration method is used for analyzing the carbon in the soil. The findings of the survey done in this experiment reveals that the organic carbon content varies from field to field even farming the same crops grown.
