The presence of organic carbon in agricultural land is regularly checked through Soil Health Card (SHC).

As per guidelines of the scheme, States to generate Soil Health Card once in three years to address nutrient deficiencies in soil. Till date, 24.60 crore SHCs have been generated.

The major reasons for decrease in organic carbon in soil are:

1. defective practices such as injudicious or excessive use of chemical fertilizer, frequent tillage / ploughing, stubble burning, overgrazing, and erosion;
2. replacing perennial vegetation with monoculture crops and pastures and
3. soil physicochemical properties such as soil bulk density, high gravel content, soil erosion and low soil water content / poor moisture conservation measures.         

To address the issue, Government is implementing Soil Health and Fertility Scheme to issue SHCs to farmers.

SHC gives the details of organic carbon content in the soil and advisories are given to the farmers on Integrated Nutrient Management (INM) for judicious use of chemical fertilizers including secondary and micro nutrients along with organic manures & bio-fertilizers, for improving soil organic carbon and health.

What government is doing?

1. The government is also promoting organic farming to improve soil organic carbon through Paramparagat Krishi Vikas Yojana (PKVY) in all the States/UTs and
2. Mission Organic Value Chain Development for North Eastern Region (MOVCDNER).
3. Union Cabinet has also approved the National Mission on Natural Farming (NMNF) on 25.11.2024 to promote farming practices such as biomass mulching, multi-cropping system, use of on-farm made natural farming bio-inputs for improving soil organic content, soil structure, nutrition, enhancing soil water holding capacity.
4. Indian Council of Agricultural Research (ICAR) has also developed several location-specific bio-engineering measures to check soil erosion due to run-off of rainwater, sand dune stabilization and shelter belt technology to check wind erosion and reclamation technology for problem soils that enhances soil organic carbon.
