  • Marshy soils develop in waterlogged districts of **Tamil Nadu**, **Bihar**, and **Uttar Pradesh**, containing exceptionally high organic content.

How Does Soil Support Climate Action and Build Resilience?

  • Soil acts as a carbon sink by absorbing atmospheric carbon dioxide and storing it as soil organic carbon through roots and soil microbes.
  • Raising soil organic carbon enhances soil structure, boosts nutrient retention, and protects crops against extreme droughts.
  • Carbon farming practices pull carbon out of the air and trap it inside farmland, making it a cornerstone of climate-smart farming.
  • India supports soil carbon storage through the **National Mission for a Green India**, the **National Mission for Sustainable Agriculture**, and the **Carbon Credit Trading Scheme**.
  • The **Green India Mission** operates as one of the eight key missions under the **National Action Plan on Climate Change**.
  • It aims to expand tree cover on degraded and non-forest lands, supporting ecosystem services and building climate resilience.
  • In line with **India's Nationally Determined Contribution**, the mission aims to create an extra carbon sink of **2.5-3.0 billion tonnes** of carbon dioxide equivalent by **2030**.
  • The **India State of Forest Report 2023** notes that India built an additional carbon sink of **2.29 billion tonnes** between **2005** and **2021**.
  • The **National Mission for Sustainable Agriculture** was introduced in **2014-15** under the **National Action Plan on Climate Change** to advance climate-resilient farming.
  • Under the Rainfed Area Development component, the government released **₹2,119.84 crore** since **2014-15**, covering **8.50 lakh hectares** and helping **14.35 lakh farmers**.
  • Launched in **2024**, the **National Mission on Natural Farming** promotes nature-based agricultural techniques to lower input expenses and raise soil organic carbon.
  • By **March 2026**, this mission covered **18,786 clusters** across **8.80 lakh hectares** with **18.19 lakh farmers** enrolled.
  • Ground support relies on **33,676** trained Community Resource Persons and specialized institutional training networks.
  • Bio-input Resource Centres furnish organic inputs like **Beejamrit** and **Jeevamrit** to replace chemical fertilizers and pesticides.
  • Established in **2023**, the **Carbon Credit Trading Scheme** offers financial rewards to entities that reduce or remove greenhouse gas emissions.
  • Under voluntary carbon markets, each verified carbon credit represents **1 metric tonne** of carbon dioxide equivalent, verified by standards like **Verified Carbon Standard** and **Gold Standard**.
  • Farmers practicing sustainable land management can sell verified carbon credits to offset buyers, generating extra income.

How Do Integrated Initiatives Strengthen Soil Health and Fertiliser Management?
