1. What It Is:
SSP is a phosphorus-based fertilizer that contains water-soluble phosphorus along with calcium and sulfur, making it useful for improving soil fertility and crop productivity, especially in phosphorus-deficient soils.
2. Chemical Composition:
- Phosphorus (P₂O₅): ~16% (water-soluble)
- Calcium (Ca): ~18–21%
- Sulfur (S): ~11–12%
- Form: Powder or granules (granular is easier to apply)
3. Applications:
- Used for crops like wheat, rice, sugarcane, pulses, fruits, and vegetables
- Especially beneficial in acidic to neutral soils
- Provides early root development and improves plant strength
4. Advantages:
- Affordable source of phosphorus
- Also adds calcium and sulfur to the soil
- Improves soil structure and microbial activity
- Suitable for basal (pre-plant) application
5. Limitations:
- Lower phosphorus concentration compared to DAP or TSP
- Not suitable for alkaline soils (limited solubility)
- Slow nutrient release
6. Storage & Handling:
- Store in dry conditions to avoid caking
- Available in powder or granular form, packed in 50 kg bags or bulk
