More about this list
About this list
India's Fertiliser (Inorganic, Organic or Mixed) (Control) Order, 1985 sets a specification for every fertiliser that may be made, imported or sold: the nutrients it must contain, its limits and how it is tested. This list brings together every fertiliser specified in Schedule I, Part A (straight and complex fertilisers, micronutrients, fortified, 100% water soluble, beneficial element and liquid fertilisers), the biofertilisers of Schedule III, the organic fertilisers of Schedule IV, the non-edible de-oiled cake of Schedule V, the nano fertilisers of Schedule VII and the organic carbon enhancers of Schedule VIII. Biostimulants (Schedule VI) have their own list.
Each specification was transcribed twice, independently, from the Order as amended up to the Ninth Amendment Order, 2026 (S.O. 4045(E), 22 Jul 2026), and the two readings were compared line by line. Values are shown as notified, including the wording of each line.
Updated as on October 2026; checked for later changes on 20 October 2026. A reference consolidation by NanoKheti, not legal advice; confirm with the Gazette notification before labelling, licensing or buying.

What is the FCO specification of urea?
Urea (46% N), Schedule I, Part A, 1(a), item 2: total nitrogen at least 46.0 per cent (dry basis), biuret not more than 1.5 per cent and moisture not more than 1.0 per cent; at least 80 per cent of the granules must stay between the 1 mm and 2.8 mm IS sieves. Neem coated urea also needs at least 0.035 per cent neem oil.
What is the FCO specification of DAP?
Diammonium phosphate (18-46-0), Schedule I, Part A, 1(e), item 1: total nitrogen at least 18.0 per cent (ammoniacal nitrogen at least 15.5), available phosphorus (as P2O5) at least 46.0 per cent, of which water soluble at least 39.5, and moisture not more than 2.5 per cent.
Which fertilisers were taken out of the FCO in 2026?
S.O. 1814(E) of 9 Apr 2026 omitted Calcium Ammonium Nitrate (25% N), Urea Ammonium Nitrate (32%N) (liquid) and Ammonium Nitrate Phosphate (23-23-0) from Schedule I. They are listed under Omitted entries below.

Which nano fertilisers are notified under the FCO?
Schedule VII lists 5: Nano Nitrogen, Nano Nitrogen, Phosphorus with and without Potassium fertiliser, Nano Phosphorus fertiliser, Nano Zinc and Nano Copper. Their specifications set particle size (under 100 nm) and, for some, the zeta potential.
What is a fortified fertiliser under the FCO?
A fertiliser to which a secondary or micronutrient (such as zinc, boron or sulphur) has been added, specified in Schedule I, Part A, item 1(h) of the Fertiliser Control Order, 1985. This list has 42 of them, each with its notified minimum and maximum values.
