Why Soil is a Strategic National Resource
- Agricultural Foundation: Soil supports crop production, sustains ecosystems, and secures rural livelihoods
- Workforce Impact: More than 46% of India's workforce engaged in agriculture and allied activities
- Land Coverage: According to Land Use Statistics 2022-23, India's total reported area is 306.65 million hectares, with nearly 59% under agriculture
- Food Security: Soil health directly affects farm incomes, food security, and economic stability
- Climate Action: Healthy soil improves crop yields, enhances water and nutrient retention, and reduces dependence on external inputs
- SDG Alignment: Soil conservation is essential for achieving SDG 2 (Zero Hunger) and SDG 13 (Climate Action)

Major Soil Types in India
| Soil Type | Regions | Key Characteristics |
|---|---|---|
| Alluvial | Indo-Gangetic, Brahmaputra plains, deltas of Mahanadi, Krishna, Godavari | Most fertile; supports intensive agriculture |
| Black | Maharashtra, Madhya Pradesh, Gujarat | Clayey, moisture-retaining, rich in lime/calcium |
| Red | Tamil Nadu, Karnataka, Andhra Pradesh, Bihar, West Bengal, Rajasthan | Porous; deficient in major nutrients |
| Laterite | High-rainfall regions of AP, Karnataka, Kerala, MP, Odisha, Assam | Formed through intense leaching |
| Desert | Rajasthan, Gujarat, Leh-Ladakh | Sandy, low moisture retention |
| Forest/Hill | Himalayan and North-Eastern regions | Varies with altitude, rainfall, temperature |
| Saline/Alkaline | UP, Punjab, Haryana, Bihar, Rajasthan, coastal Odisha, Sundarbans | Affected by poor drainage/waterlogging |
| Marshy | Tamil Nadu, Bihar, Uttar Pradesh | High organic matter content |
Soil and Climate Action
Soil as Carbon Sink
- Soil absorbs atmospheric CO2 and stores it as soil organic carbon
- Long-term storage helps reduce greenhouse gas concentrations
- Benefits include improved soil structure, nutrient availability, moisture retention, and drought resilience
Carbon Farming
- Promotes sustainable land-management practices
- Removes carbon from atmosphere and stores in soil
- Important component of climate-smart agriculture
National Mission for a Green India
- Part of National Action Plan on Climate Change
- Aims to create additional carbon sink of 2.5-3.0 billion tonnes CO2 equivalent by 2030
- India created 2.29 billion tonnes CO2 equivalent carbon sink (2005-2021)
Carbon Credit Trading Scheme (2023)
- Creates financial incentives for emission reduction activities
- Farmers can sell verified carbon credits for emission offsets
- Supported by Verified Carbon Standard and Gold Standard
Digital Soil Ecosystem
