Question map
With reference to chemical fertilizers in India, consider the following statements : 1. At present, the retail price of chemical fertilizers is market-driven and not administered by the Government. 2. Ammonia, which is an input of urea, is produced from natural gas. 3. Sulphur, which is a raw material for phosphoric acid fertilizer, is a by-product of oil refineries. Which of the statements given above is/are correct ?
Explanation
The correct answer is Option 2 (2 and 3 only). Below is the comprehensive explanation:
- Statement 1 is incorrect: The retail price of chemical fertilizers in India is not entirely market-driven. Urea is under statutory price control, and its Maximum Retail Price (MRP) is fixed by the Government. For Non-Urea fertilizers (DAP, MOP, NPK), the government implements the Nutrient Based Subsidy (NBS) scheme, where it provides a fixed subsidy, though it still monitors prices to keep them affordable.
- Statement 2 is correct: Ammonia ($NH_3$) is a critical precursor for Urea. In India, the majority of ammonia is produced through the Haber process using natural gas (methane) as the primary feedstock for hydrogen.
- Statement 3 is correct: Sulphur is a vital raw material for manufacturing phosphoric acid. It is primarily obtained as a by-product during the desulphurization of crude oil in petroleum refineries and natural gas processing.
Therefore, since statements 2 and 3 are factually accurate while statement 1 is false, Option 2 is the right choice.
PROVENANCE & STUDY PATTERN
Full viewThis question perfectly bridges Economy (Subsidy Policy) and Geography (Industrial Inputs). Statement 1 is the 'Gatekeeper'—knowing Urea is still under price control eliminates the extreme 'market-driven' claim. Statements 2 and 3 reward those who studied the *supply chain* of industries, not just the final output.
This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.
- Statement 1: As of 2020, are retail prices of chemical fertilizers in India market-driven (decontrolled) or administered by the Government?
- Statement 2: In India, is ammonia used as an input for industrial urea fertilizer production?
- Statement 3: In India, is ammonia for urea production manufactured from natural gas?
- Statement 4: In India, is sulphur used as a raw material in production of phosphoric acid for phosphate fertilizers?
- Statement 5: In India, is sulphur commonly recovered as a by-product from oil refineries?
- Explicitly states urea prices are regulated/fixed by the Government while DAP, MoP and Complex Fertilizers have been deregulated (market driven).
- Directly contrasts the regulatory status of different fertilizer categories, supporting a mixed (partially administered, partially market-driven) regime.
- Says producers and importers of DAP and MOP are free to sell these fertilizers at any price, i.e., market-driven.
- Explains government role is limited to paying a fixed nutrient-based subsidy for these fertilizers, not price control.
- Describes Government-set controlled Maximum Retail Price (MRP) for urea and subsidy payment mechanism to cover cost difference.
- Notes other administrative controls for urea (import canalisation and directed movement), reinforcing that urea retail price is administered.
- Explicitly identifies ammonia as a key input in urea manufacturing.
- Describes industrial production of ammonia (Haber-Bosch) and its subsequent use to produce urea.
- States ammonia is produced by the Haber-Bosch process from nitrogen and hydrogen.
- Says this ammonia is subsequently used to manufacture urea, linking ammonia as the input for urea.
- Direct, concise statement that ammonia is an input of urea.
- Connects ammonia production to natural gas, supporting industrial production context.
Explicitly states a rule-like claim: 'Ammonia, which is an input of urea, is produced from natural gas.'
A student could combine this with basic chemistry knowledge (that industrial urea is made from ammonia + CO2 via the urea process) to infer ammonia is an industrial input to urea production.
Gives an industry-level pattern: of 31 urea units, 28 use natural gas (domestic gas/LNG/CBM) and 3 use naphtha as feedstock.
Knowing natural gas is a common feedstock for producing ammonia (via reforming to make hydrogen), a student can infer these plants likely produce ammonia on-site or use ammonia derived from that feedstock for urea manufacture.
Repeats the triad of related facts in exam-style form: that ammonia is an input of urea and is produced from natural gas (statement presented for evaluation).
A student can treat this as authoritative textbook framing and check standard industrial links (natural gas → ammonia → urea) to judge the statement's plausibility.
Describes the fertiliser industry structure and nitrogenous products, noting many units produce urea and some produce ammonium sulphate as a by-product.
From industry outputs (nitrogenous fertilisers and ammonium salts) one can infer widespread industrial handling of ammonia/nitrogen intermediates that are used to make urea.
- States that the vast majority of urea manufacturing units use Natural Gas (domestic gas/LNG/CBM) as feedstock.
- Implicates that the urea production process in India is predominantly gas-based, which is the route for producing ammonia intermediates used in urea.
- Describes policy of pooling domestic and imported gas to supply natural gas to gas-grid-connected urea plants for manufacturing urea.
- Refers explicitly to 'gas-based urea plants', confirming that urea (and its ammonia input) is produced via natural gas feedstock.
- Notes limited availability of domestic gas has forced urea producers to depend on imported (costly) gas for production.
- Links gas supply (domestic or imported) directly to urea production, reinforcing that natural gas is the feedstock used.
- Explicitly lists sulphur among the basic raw materials for the fertiliser industry.
- Pairs rockphosphate (the phosphate source) with sulphur as primary inputs for fertiliser manufacture.
- Names an Indian plant (Paradeep) that produces both phosphoric acid and sulphuric acid.
- Shows domestic production capacity for both acids, implying industrial linkage between sulphur/sulphuric acid and phosphatic fertiliser production.
- Explicitly states sulfur is sourced from oil refineries as a by-product.
- Connects this sulfur use to fertilizer production (phosphoric acid), directly tying to the Indian fertilizer context.
- Directly labels sulphur as a by-product of oil (refineries), supporting the claim.
- Mentions sulphur's role as a raw material for phosphoric acid fertilizer, reinforcing context.
- Affirms that sulfur used in phosphoric acid fertilizers is a by-product of oil refineries.
- Describes industrial context (Contact process) linking recovered sulfur to fertilizer manufacture.
A textbook multiple‑choice item explicitly asserts: 'Sulphur ... is a by‑product of oil refineries' as the premise of a question about fertiliser inputs.
A student could treat this as a commonly taught claim and check refinery product lists or industrial chemistry sources to verify if Indian refineries recover elemental/industrial sulphur.
States sulphur is a basic raw material for the fertiliser industry and notes most fertiliser plants are located close to petroleum refineries.
A student could infer that proximity implies a local source (e.g., refinery by‑products) and then examine regional refinery outputs or transport patterns to see if sulphur is supplied from refineries.
Explains refineries remove impurities from crude oil to obtain finished products, implying extraction/processing of impurity streams.
A student could connect 'impurities removed' with known impurities containing sulphur and then consult refinery processing steps (desulphurisation) to assess whether recovered sulphur is generated.
Describes petroleum refineries as a 'nodal industry' for fertiliser and chemical industries, suggesting close material linkages between refineries and fertiliser feedstocks.
A student might use this to hypothesize that refineries supply feedstocks (including sulphur or sulphur compounds) to nearby fertiliser plants and then look up supply chains or plant feedstock sources.
- [THE VERDICT]: Standard-Applied Hybrid. Statement 1 is basic Economy (Vivek Singh/Singhania); S2 & S3 are Geography/Science common sense found in Majid Husain (Industries).
- [THE CONCEPTUAL TRIGGER]: Fertilizer Subsidy Regime & Industrial Location Factors.
- [THE HORIZONTAL EXPANSION]: 1. Urea: Controlled MRP, Gas-based (Haber Process). 2. DAP/MoP: NBS regime (Decontrolled), P & K based. 3. Potash: India is 100% import dependent (No reserves). 4. Rock Phosphate: Jhamarkotra mines (Rajasthan) vs Imports (Morocco/Jordan). 5. Sulphur: By-product of desulphurization in refineries (BS-VI norms increased sulphur recovery).
- [THE STRATEGIC METACOGNITION]: When studying a core sector (Steel, Fertilizer, Power), map the Input-Output Linkage. Don't stop at 'Govt gives subsidy'; ask 'What raw material is used?' (Coal/Gas/Sulphur) and 'Where does it come from?'.
Urea retail price is government-administered while DAP, MoP and complex fertilizers are deregulated and market-driven.
High-yield because questions often probe which commodities remain price-controlled versus market liberalized; links to subsidy policy, procurement and distribution issues. Mastering this helps answer mixed-regime policy questions and compare sectoral regulation across agriculture inputs.

The government sets urea pricing and provides production subsidies, and directs aspects of urea distribution.
Crucial for public policy and governance questions: understanding administered prices and subsidy mechanisms enables analysis of fiscal burden, market distortions, and reform proposals (e.g., direct transfers or deregulation). This ties into public finance, industrial policy and rural economy questions.

Potash (MoP) is the only major fertilizer for which India has ZERO commercially exploitable reserves and is 100% import-dependent. (Sibling to the Sulphur/Gas facts).
The 'Sensitive Commodity' Heuristic. In India, essential goods (Food, Fuel, Fertilizer) rarely have *fully* market-driven pricing. Statement 1 claims *all* chemical fertilizers are market-driven. Since Urea is politically sensitive, this blanket deregulation is highly improbable. Eliminate 1.
Energy-Food Nexus (Mains GS-3): High Global Gas prices -> High Ammonia cost -> High Fertilizer Subsidy Bill -> Fiscal Deficit. This links IR (Ukraine War/Gas prices) directly to Indian Economy (Fiscal Deficit).
