Are You Buying the Bag or the Nutrient?
Fertilizer prices fluctuate constantly. A bag of SSP might look cheap, but does it actually provide the cheapest Phosphorus compared to a bag of DAP? The Phosphorus Cost Saver removes the guesswork. This tool compares the five major Phosphorus sources—DAP, SSP, NP, TSP, and MAP—to calculate exactly how much you are paying for every kilogram of Phosphorus (P₂O₅).
Why use this tool?
- Save Money: Identify which fertilizer offers the best value for money at current market rates.
- Optimize Yield: Ensure you are applying the correct amount of nutrients within your budget.
- Smart Decisions: Compare high-concentration fertilizers (like MAP/DAP) against low-concentration ones (like SSP) instantly.
Fertilizer Comparison
Standard Bag Weight: 50 kg (Default)
| Fertilizer Name | Abbreviation | Nitrogen (N) | Phosphorus (P₂O₅) | Sulphur (S) |
| Diammonium Phosphate | DAP | 18% | 46% | 0% |
| Single Super Phosphate | SSP | 0% | 18% | 11-12% |
| Nitrophos | NP | 22% | 20% | 0% |
| Triple Super Phosphate | TSP | 0% | 46% | 0% |
| Monoammonium Phosphate | MAP | 11% | 52% | 0% |
How to Read the Results:
- Pure Phosphorus Cost: This tool calculates the cost based strictly on Phosphorus content.
- The Nitrogen Factor: Remember that DAP, MAP, and NP also contain Nitrogen. If you use SSP or TSP, you may need to buy extra Urea to match the Nitrogen levels found in DAP.
- The Sulfur Bonus: SSP contains roughly 11% Sulfur. If your soil is Sulfur deficient, SSP might be the better choice even if the Phosphorus cost is slightly higher than TSP.
- Solubility: MAP and NP are generally more acidic and water-soluble, making them excellent for high-pH soils.
