Fertilizer Security, Causes, Impacts, Reforms, Implications

India’s fertiliser security is under significant strain due to structural challenges such as excessive dependence on urea, rising import reliance, and inefficient nutrient usage. With over 80% of nitrogen consumption met through urea, the system has become both economically and environmentally unsustainable. This imbalance has escalated the subsidy burden, degraded soil health, and increased vulnerability to global supply chain disruptions, making fertilizer security a critical concern for long-term agricultural sustainability.

Structural Drivers of the Fertilizer Crisis in India

India’s fertilizer crisis stems from interconnected structural issues in consumption, production, and policy design.

• Urea-Dominated Nitrogen Consumption: Urea accounts for the majority of nitrogen use due to its low, subsidized price, leading to imbalanced nutrient application and soil degradation.
• Rising Import Dependence: Increasing demand and stagnant domestic production have led to higher imports of urea and key inputs like LNG, ammonia, and sulphur, creating external vulnerability.
• Dependence on Imported Natural Gas: Nearly 85% of natural gas required for urea production is imported, linking domestic output to global energy price fluctuations.
• Distorted Subsidy Structure: Urea receives heavy subsidies, while non-urea fertilizers under the Nutrient Based Subsidy Scheme receive lower and capped support, resulting in skewed price incentives.
• Low Nitrogen Use Efficiency (NUE): Inefficient fertilizer application leads to significant nutrient loss, increasing demand without proportional productivity gains.

Implications of the Fertilizer Crisis in India

India’s fertilizer imbalance has wide-ranging consequences across economic, environmental, and strategic dimensions.

• Fiscal Pressure on Government Finances: Rising fertilizer imports and heavy urea subsidies significantly increase the subsidy burden on the Union Budget.
• Widening Current Account Deficit: Higher import of fertilizers, LNG, and inputs like ammonia and sulphur adds pressure on India’s foreign exchange reserves and external balance.
• Soil Degradation and Nutrient Imbalance: Excessive use of urea disrupts soil nutrient balance, reduces fertility over time, and affects long-term agricultural productivity.
• Water Pollution and Environmental Stress: Nitrogen leaching leads to groundwater contamination, while excessive use contributes to greenhouse gas emissions such as nitrous oxide.
• Agronomic Inefficiency: Low nitrogen use efficiency results in fertilizer wastage and diminishing returns in crop yield despite higher input use.
• Strategic Vulnerability: Dependence on imports of fertilizers and energy inputs from a few regions, especially the Gulf, exposes India to geopolitical and supply chain risks.
• Food Security Risks: Any disruption in fertilizer supply directly impacts agricultural output, threatening food security in a highly agriculture-dependent economy.

Therefore, there is a need for a comprehensive and long-term strategy to ensure fertilizer security and promote balanced nutrient management.

Strategies to Address India’s Fertilizer Crisis and Ensure Fertilizer Security

India requires a multi-pronged strategy addressing supply-side constraints, demand-side inefficiencies, and policy distortions to build long-term fertilizer security.

Enhancing Domestic Production Resilience: 

• Diversify feedstock usage by promoting mixed fuel (gas + naphtha) flexibility in urea plants during LNG shortages.
• Allow continued use of coal-based utilities for steam and power where cost-effective.
• Upgrade and modernize old fertilizer plants to improve energy efficiency and output capacity.
• Strengthen domestic gas availability through infrastructure expansion and long-term import contracts.

Transition towards Green Fertilizers: 

• Promote production of green ammonia using renewable energy sources to reduce fossil fuel dependence.
• Develop pilot and demonstration plants for green urea to resolve techno-economic challenges.
• Gradually substitute grey ammonia with green ammonia in existing fertilizer plants.
• Aim for a phased target of 20–25% nitrogen fertilizer production through green routes.

Diversification of Fertilizer Use: 

• Increase the share of NP/NPK complex fertilizers to promote balanced nutrient application.
• Encourage use of ammonium sulphate for sulphur-deficient soils and specific crops like oilseeds.
• Reduce overdependence on urea by promoting soil-specific fertilizer combinations.

Improving Nitrogen Use Efficiency (NUE): 

• Promote site-specific nutrient management (SSNM) practices.
• Encourage use of organic manure, biofertilizers, and biochar to improve soil health.
• Strengthen extension services to educate farmers on efficient fertilizer application.
• Aim to improve NUE through precision agriculture techniques.

Reforming Subsidy and Policy Framework: 

• Rationalize fertilizer subsidies to reduce distortion between urea and non-urea fertilizers.
• Align subsidies with nutrient content rather than product type.
• Improve implementation of the Nutrient Based Subsidy Scheme to ensure balanced fertilization.
• Introduce price signals that discourage overuse of urea.

Strengthening Institutional and Technological Support: 

• Invest in R&D for green fertilizers and efficient production technologies.
• Promote digital agriculture tools for real-time soil and nutrient management.
• Enhance coordination between government, industry, and research institutions.
