Sodium Tripolyphosphate (STPP)
Sodium Tripolyphosphate (STPP)
Sodium Tripolyphosphate (STPP) is a versatile phosphate compound widely used in agriculture as a soil conditioner, dispersing agent, and nutrient stabilizer. It enhances the availability of phosphorus, improves soil structure, and supports plant metabolic functions. STPP is also valued for its ability to chelate metal ions, prevent nutrient lock-up, and increase fertilizer efficiency in various cropping systems.

Key Features & Benefits
1)Supplies plant-available phosphorus (P₂O₅) for healthy growth and yield.
2)Acts as a chelating and sequestering agent, preventing micronutrient precipitation.
3)Improves fertilizer efficiency by reducing nutrient fixation in alkaline soils.
4)Enhances soil structure and aeration for better root development.
5)Promotes energy transfer and photosynthesis in plants.
6)Compatible with other fertilizers in fertigation and foliar use.
7)Improves water penetration and nutrient distribution in soil.
