Triple superphosphate (TSP) is a high-analysis phosphorus fertilizer, primarily composed of monocalcium phosphate with the chemical formula Ca(H2PO4)2 · H2O.
It typically contains 44-48% phosphorus pentoxide (P2O5) and about 15% calcium, making it one of the most concentrated sources of phosphorus available for agricultural use.
Triple Super Phosphate Price in India
The price of Triple Super Phosphate (TSP) in India varies based on the supplier and the form of the product. Here are some key price points:
- Kanha Life Science LLP lists TSP at 200 INR per kilogram with a minimum order quantity of 25 kilograms.
- S M A Chemicals offers TSP at approximately 100 INR per kilogram, also with a minimum order of 100 kilograms.
- Other suppliers have reported prices ranging from 15 to 18 INR per kilogram in certain regions like Mizoram.
Market Trends
In terms of market trends, the spot price for TSP has recently been reported at 491 USD per metric ton as of November 2024, reflecting a decrease from the previous month but an increase from the same time last year.
Overall, the prices can fluctuate based on market conditions, demand, and supplier specifics.
Production Process
The production of TSP involves reacting finely ground phosphate rock with phosphoric acid. This can be done in two forms:
- Nongranular TSP: Produced by mixing the phosphate rock with phosphoric acid.
- Granular TSP: Created by spraying the slurry onto small particles to form granules, which are then cured for several weeks to complete the chemical reactions.
Agricultural Use
TSP has several agronomic advantages:
- High Solubility: Over 90% of the phosphorus in TSP is water-soluble, allowing for rapid plant uptake.
- Ideal for Legumes: It is particularly beneficial for leguminous crops, such as alfalfa and beans, where additional nitrogen is not required due to biological nitrogen fixation.
- Application Versatility: TSP can be blended with other fertilizers and used in various application methods, including broadcasting and banding beneath the soil surface.
Decline in Popularity
Despite its advantages, TSP's usage has declined since the mid-1970s as ammonium phosphate fertilizers (like monoammonium phosphate) have gained popularity due to their higher total nutrient content and lower production costs. Consequently, TSP is less favored in many agricultural contexts today.
Non-Agricultural Uses
Beyond agriculture, monocalcium phosphate (a component of TSP) is also utilized in baking powder and as a mineral supplement in animal feeds.
