Single Super Phosphate (SSP) Specification:
Single Super Phosphate (SSP) is a widely used phosphorus-based fertilizer. It is made by reacting phosphate rock with sulfuric acid to produce a product that is rich in water-soluble phosphorus. SSP typically contains:
- 16-22% Phosphorus (P2O5) (in a water-soluble form)
- 11-12% Sulfur
- 18-21% Calcium
Functions of SSP in Planting:
-
Phosphorus Supply:
- Phosphorus is critical for plant growth as it promotes root development, flowering, fruiting, and seed production.
- SSP provides phosphorus in a readily available form for plants.
-
Sulfur Addition:
- Sulfur helps in protein synthesis and enzyme function, which are essential for plant metabolism.
- It is particularly beneficial for crops like oilseeds, pulses, and cereals.
-
Calcium Enrichment:
- Calcium helps strengthen plant cell walls, improving structural integrity and resistance to diseases.
-
Improves Soil Quality:
- SSP releases phosphate ions that help improve soil structure and nutrient-holding capacity.
-
Enhances Root Growth:
- Phosphorus encourages the formation of strong, healthy root systems, helping plants absorb water and nutrients more effectively.
-
Early Plant Development:
- It accelerates seedling emergence and overall early plant vigor.
Suitable Crops for SSP:
- SSP is suitable for a wide range of crops, including cereals (wheat, rice, maize), oilseeds (mustard, groundnut), pulses (lentils, chickpeas), vegetables, and fruit crops.
It is commonly applied during land preparation, mixed into the soil to ensure even distribution and nutrient availability to young plant
