Urea doesn’t begin in the soil it begins in a gas market most farmers never see.
In India, nearly 70–80% of urea production cost is tied to natural gas, with a significant share coming from imported LNG linking fertilizer directly to global energy volatility (Ministry of Chemicals & Fertilizers, Govt. of India).
When Geopolitics Reached the Field
While following geopolitical developments, I came across reports of tensions involving the Strait of Hormuz a critical route through which much of the world’s LNG supply moves, including shipments to India.
Around the same time, I spoke to farmer friends growing paddy locally and asked if anything had changed. Their response was direct: urea supply was being restricted only one bag allowed for four acres through Aadhaar-linked distribution, something they hadn’t experienced before.
That’s when the connection became clear what looks like a distant geopolitical event can quietly tighten input access at the farm level.
The Chemistry Behind Urea Production
Urea production begins with ammonia, made possible at industrial scale by Fritz Haber and Carl Bosch. Their work allowed atmospheric nitrogen to be converted into ammonia the foundation of all nitrogen fertilizers.
At its core, urea is formed when ammonia reacts with carbon dioxide under high pressure, first creating ammonium carbamate and then urea. This process has remained fundamentally unchanged for nearly a century.
Why Natural Gas Became the Backbone
Natural gas, mainly methane (CH₄), plays two critical roles it provides hydrogen for ammonia synthesis and supplies the energy required for the process.
Compared to older feedstocks like naphtha, gas-based systems are more efficient, involve fewer processing steps, and offer better conversion rates. This is why modern fertilizer plants are designed almost entirely around natural gas.
Where LNG Fits Into This Chain
India does not have enough domestic natural gas to meet fertilizer demand. To bridge this gap, it imports Liquefied Natural Gas (LNG), which is regasified and supplied to fertilizer plants.
This creates a direct dependency:
No gas → No ammonia → No urea
Once LNG enters the system, fertilizer production is no longer just an industrial process it becomes linked to global energy markets.
India’s Shift: From Naphtha to Natural Gas
In the early decades, Indian fertilizer plants relied on naphtha and fuel oil. These inputs made production expensive, inefficient, and technically complex.
The transition began in the 1990s, driven by economic reforms, domestic gas discoveries, and global shifts toward gas-based ammonia production. Over time, plants were converted, and new ones were built entirely around natural gas.
From a technical standpoint, this shift was the right decision cleaner, simpler, and more efficient.
When Cost Shifted from Process to Fuel
In the naphtha era, high costs were driven by inefficient processes. In the gas era, production became more efficient but the cost structure changed fundamentally.
The key shift:
Cost moved from internal inefficiency to external fuel dependency.
The Real Policy Equation
While production costs became volatile, urea prices for farmers remained fixed.
This created a structural equation:
Subsidy ∝ Gas Price
As LNG prices rise, the government absorbs the difference through subsidies to keep urea affordable (Ministry of Chemicals & Fertilizers, Govt. of India).
What This Led To
India now operates a system where:
- Production is technically efficient
- But financially volatile
The fertilizer subsidy bill fluctuates not because of inefficiency but because of exposure to global gas prices.
Policy Response to a Volatile System
To manage this, India introduced the New Pricing Scheme (NPS) and later the Direct Benefit Transfer (DBT) system.
These reforms aimed to control subsidy leakage, standardize pricing mechanisms, and adjust for plant-wise cost differences (Press Information Bureau, Govt. of India).
LNG Dependency Became Structural
With limited domestic gas, LNG imports became essential to sustain production.
This means India’s fertilizer system is now exposed to:
- Global price shocks
- Supply disruptions
- Geopolitical risks
What started as an efficiency upgrade has evolved into a structural dependency (NITI Aayog).
Why Nano Urea Is Being Pushed
Nano urea is being positioned as a way to reduce this dependency.
The logic is simple:
- Lower gas requirement
- Lower subsidy burden
- Higher nitrogen use efficiency (in theory)
It also offers logistical advantages smaller volumes, easier transport, and reduced storage challenges.
The Reality Check (Don’t Ignore This)
However, nano urea is not a full replacement.
- It works as a supplement, not a substitute
- Performance varies across crops and conditions
- Farmer adoption is still uneven
The real positioning is clear:
Nano urea is a policy and efficiency intervention not a complete agronomic solution.
The Strategic Trade-Off
India made the right technical shift from naphtha to natural gas.
But in doing so, it replaced one limitation with another:
From process inefficiency
to fuel price vulnerability

Something to Think About
If fertilizer production depends on imported energy, then agriculture is no longer just a soil issue it’s an energy security issue.
