Meaning
NBS stands for Nutrient Based Subsidy.
It is a fertiliser subsidy policy under which subsidy is fixed on the basis of the nutrient content of fertilisers, not simply on the fertiliser product itself.
It mainly applies to phosphatic and potassic fertilisers, commonly called P&K fertilisers.
Background
Before NBS, fertiliser subsidy was largely product-based. This created price distortions and encouraged excessive use of some fertilisers.
Urea remained highly subsidised and cheap, while other fertilisers became relatively expensive. This disturbed the ideal balance of nutrients in soil.
To address this, the government introduced the Nutrient Based Subsidy Scheme in 2010.
Nutrients Covered
Under NBS, subsidy is provided for key plant nutrients such as:
- Nitrogen
- Phosphorus
- Potash
- Sulphur
Some secondary and micronutrients may also be supported when present in notified fertilisers.
How It Works
The government fixes a per-kg subsidy rate for each nutrient.
The subsidy amount for a fertiliser depends on how much nutrient it contains.
For example, if a fertiliser contains more phosphorus or potash, the subsidy is calculated according to the nutrient quantity present in it.
This is meant to encourage balanced fertiliser use rather than excessive dependence on one fertiliser.
Fertilisers Covered
NBS mainly covers non-urea fertilisers such as:
- DAP
- MOP
- NPK complex fertilisers
- SSP
- Other notified P&K fertilisers
Urea is not covered under NBS. Urea continues under a separate price-controlled subsidy system.
Objectives
The main objectives of NBS are:
- Promote balanced fertiliser use
- Improve soil health
- Reduce excessive urea dependence
- Encourage use of P&K fertilisers
- Improve nutrient-use efficiency
- Rationalise fertiliser subsidy
- Encourage competition among fertiliser companies
- Support farmers by making fertilisers affordable
Importance
NBS is important because Indian agriculture has long faced nutrient imbalance.
Farmers often use more nitrogen because urea is cheaper. But crops also need phosphorus, potash, sulphur and micronutrients.
Imbalanced fertiliser use can cause:
- Soil nutrient depletion
- Decline in soil fertility
- Lower crop productivity over time
- Higher input cost without proportional yield gain
- Environmental pollution
- Poor nutrient-use efficiency
NBS tries to shift focus from fertiliser quantity to nutrient quality.
Difference Between Urea Subsidy and NBS
Urea subsidy
Urea price is controlled by the government. It remains very cheap for farmers. This encourages overuse of nitrogen.
NBS
Subsidy is linked to nutrient content. Companies have more freedom in pricing P&K fertilisers, but subsidy support is given according to nutrients.
Benefits
NBS has several advantages.
It supports balanced fertilisation.
It gives farmers access to different nutrient combinations.
It encourages fertiliser companies to produce customised and complex fertilisers.
It reduces the burden of product-specific subsidy distortions.
It supports better soil health if combined with soil testing and farmer awareness.
Limitations
NBS has not fully solved India’s fertiliser imbalance problem.
The biggest limitation is that urea is outside NBS.
Because urea remains much cheaper than P&K fertilisers, farmers still tend to overuse nitrogen.
Other limitations include:
- High global prices of imported fertilisers
- Price rise in DAP and MOP affecting farmers
- Continued imbalance in N:P:K ratio
- Low farmer awareness about soil nutrients
- Weak use of Soil Health Cards
- Limited adoption of customised fertilisers
- Fertiliser subsidy burden remains high
Link with Soil Health
NBS is closely linked with soil health.
Balanced use of nitrogen, phosphorus, potash and sulphur helps maintain soil fertility.
However, for real improvement, NBS must be combined with:
- Soil testing
- Soil Health Cards
- Organic manure
- Micronutrient management
- Efficient irrigation
- Crop-specific fertiliser planning
- Farmer education
Way Forward
NBS can be improved through:
- Gradual inclusion of urea under a nutrient-based framework
- Direct Benefit Transfer of fertiliser subsidy to farmers
- Promotion of balanced fertiliser use
- Stronger soil testing infrastructure
- Awareness about N:P:K ratio
- Encouragement of organic and bio-fertilisers
- Better targeting of subsidies
- Promotion of nano fertilisers and customised fertilisers
- Reduction of import dependence in P&K fertilisers
Conclusion
The Nutrient Based Subsidy Scheme is an important fertiliser reform aimed at promoting balanced nutrient use and improving soil health.
However, its impact is limited because urea remains outside the scheme and continues to be heavily subsidised.
For NBS to become more effective, India needs to correct urea overuse, strengthen soil-based fertiliser application and move towards sustainable nutrient management in agriculture.
