2.Government Fertilizer Policy Reform

Why in News?

Recent geopolitical tensions in West Asia have exposed India’s heavy dependence on fertilizer imports, with nearly 70% of its requirement being sourced from abroad. This has renewed the debate on reforming India’s fertilizer policy.

What is Fertilizer Policy Reform?

• Fertilizer policy reform refers to the transition from a highly subsidized and government-controlled pricing system to a more efficient, targeted, and market-oriented framework.
• The objective is to reduce fiscal burden, improve nutrient efficiency, prevent diversion of fertilizers, and ensure sustainable agricultural practices.

Key Data and Statistics

• India depends on imports for about 70% of its fertilizer needs and raw materials.
• The country consumes nearly 40 million tonnes of urea annually, of which a significant portion is either imported directly or produced using imported natural gas.
• Global fertilizer prices are highly volatile, as seen during the 2026 West Asia conflict when urea prices rose sharply.
• The efficiency of urea use is low, with only around 35–40% of applied nitrogen actually utilized by crops, while the rest is lost to the environment.

Existing Fertilizer Policy Framework

• India follows a dual system for fertilizer pricing and subsidies.
• Urea remains under price control, with the government fixing its Maximum Retail Price at a highly subsidized level and compensating manufacturers through subsidies.
• For phosphatic and potassic fertilizers, a Nutrient-Based Subsidy system is followed, where subsidy is linked to nutrient content while market prices are relatively flexible.
• The government has also introduced neem-coated urea to reduce diversion for industrial use and improve nutrient release efficiency.
• Additionally, the Direct Benefit Transfer system ensures that subsidies are released to companies only after actual sales to farmers are verified through Aadhaar-enabled systems.

Importance of Fertilizer Policy

• Fertilizer policy plays a crucial role in ensuring food security by maintaining adequate crop productivity.
• It keeps fertilizers affordable for farmers, protecting them from global price shocks.
• It also influences soil health by promoting balanced use of nutrients.
• Efficient fertilizer use contributes to environmental sustainability and helps reduce greenhouse gas emissions.

Challenges in the Current System

• The fertilizer subsidy system places a heavy burden on the government’s finances, especially when global prices rise.
• The artificially low price of urea leads to its excessive use, causing nutrient imbalance in soils and environmental degradation.
• There is also diversion of subsidized fertilizers to non-agricultural uses due to price differences.
• India’s dependence on imports makes the system vulnerable to global supply disruptions and geopolitical tensions.
• Furthermore, tenant farmers often do not receive benefits because subsidies are linked to land ownership rather than actual cultivation.

Way Forward

• There is a need to gradually shift towards direct cash transfers to farmers, allowing them to purchase fertilizers at market prices.
• Introducing quantitative rationing can help control excessive use of urea.
• Promoting balanced fertilizers and alternatives such as liquid fertilizers and fertigation can improve efficiency.
• Encouraging technological solutions like soil testing and precision agriculture can ensure optimal nutrient use.
• Reducing import dependence through domestic production and diversification of supply sources is also essential.

Conclusion

• India’s fertilizer policy requires a fundamental shift from price-based subsidies to efficiency-based support systems.
• Reforms should aim at balancing farmer welfare, fiscal sustainability, and environmental protection.
• A well-designed policy will not only strengthen agricultural productivity but also enhance India’s long-term economic and strategic resilience.
