Samples of Diammonium Phosphate (DAP) and Ammonium Phosphate Sulphate (APS), manufactured by IFFCO, were found "non-standard" in Vidisha, Madhya Pradesh in January 2026.
A sample of Triple Super Phosphate (TSP), manufactured by Indian Potash Limited (IPL), was also found non-standard in Vidisha.
Detailed Insights:
The substandard fertiliser samples were discovered during the current Rabi season (2025-26) in Agriculture Minister Shivraj Singh Chouhan’s constituency.
DAP (18-46-0) is used by farmers at the time of sowing as it helps in germination of seeds; the analysis of the sample collected on December 20, 2025, revealed deficiencies in nitrogen and phosphorus content.
APS (20:20:0:13) is used for crops like oilseeds, pulses, sugarcane, paddy, and cotton; the sample collected on December 1, 2025, showed lower content of phosphorus and sulphur.
IPL has submitted an application for second reference analysis of the TSP sample as per the provisions of the Fertilizer Control Order (FCO).
The Agriculture Minister has urged farmers to report issues of substandard agricultural inputs to the helpline center.
These incidents raise concerns about the quality control mechanisms in place for fertilizers, especially as the government prepares for the Kharif season.
Key Concepts Involved:
Diammonium Phosphate (DAP): A widely used fertilizer containing nitrogen and phosphorus, essential for seed germination.
Ammonium Phosphate Sulphate (APS): A fertilizer containing nitrogen, phosphorus, and sulphur, used for various crops.
Triple Super Phosphate (TSP): A fertilizer containing a high percentage of phosphate, promoting root development and fruiting.
Fertilizer Control Order (FCO): An order to ensure the quality and regulate the sale, distribution, and pricing of fertilizers.
