Introduction

The Green Revolution enabled India to achieve food self-sufficiency through intensive use of chemical fertilizers, particularly urea. However, excessive and imbalanced fertilizer application has created a “fertilizer trap”, characterised by declining soil fertility, environmental degradation and rising subsidy burdens, threatening long-term agricultural sustainability and food security.

Causes of Excessive Dependence on Chemical Fertilizers

Subsidy Distortions

  • Urea is heavily subsidised under the Nutrient Based Subsidy (NBS) regime’s partial exclusion, making it cheaper than balanced nutrients like potash and phosphates.
  • This has led to excessive N:P:K imbalance; ideal ratio of 4:2:1 is distorted in many states.

Green Revolution Cropping Pattern

  • Water-intensive crops such as rice and wheat require high fertilizer inputs.
  • Monoculture farming depleted micronutrients in soil.

Declining Soil Organic Matter

  • Reduced use of organic manure and traditional practices increased dependence on synthetic fertilizers.

Lack of Awareness and Extension Services

  • Farmers often apply fertilizers indiscriminately due to poor soil testing and weak agricultural extension systems.

Policy and Market Factors

  • Assured procurement under MSP incentivises intensive cultivation.
  • Domestic production constraints increase import dependence for phosphatic and potassic fertilizers.

Consequences of the Fertilizer Trap

  • Soil degradation and micronutrient deficiencies.
  • Groundwater contamination and eutrophication.
  • Rising greenhouse gas emissions, especially nitrous oxide.
  • Declining fertilizer response ratio affecting productivity.
  • Escalating fertilizer subsidy burden on the exchequer.

Measures to Enhance Fertilizer Use Efficiency

Technological Measures

  • Promote Nano Urea and slow-release fertilizers.
  • Expand soil health cards and precision farming techniques.
  • Encourage fertigation and drip irrigation under PMKSY.

Sustainable Agricultural Practices

  • Increase use of:

    • Organic manure
    • Biofertilizers
    • Green manuring
    • Crop rotation

  • Promote natural farming and integrated nutrient management.

Policy Reforms

  • Rationalise fertilizer subsidies and expand nutrient-based pricing.
  • Diversify procurement beyond rice and wheat.
  • Strengthen research through institutions like ICAR.

Institutional and Awareness Measures

  • Improve agricultural extension services and digital advisories.
  • Encourage Farmer Producer Organisations (FPOs) for sustainable input management.

Value Addition

  • M.S. Swaminathan Committee stressed balanced nutrient application and soil sustainability.
  • FAO advocates Integrated Plant Nutrient Management (IPNM) for long-term food security.

Conclusion

India’s fertilizer trap reflects the unintended consequences of input-intensive agriculture. Ensuring sustainable food security now requires shifting from quantity-centric fertilizer use to efficiency-driven, ecologically balanced nutrient management supported by technological innovation and policy reform.
