TSP (Triple Superphosphate) is a concentrated phosphate fertilizer that maximizes the benefits of straight P, without complicating the formula with other nutrients that may not always be needed. TSP has a phosphate concentration of 46% (P2O5), is highly customizable, and can be used directly for soil fertilization or as raw material for blends. At least 90% of the total P within TSP is water soluble, so it becomes rapidly available for plant uptake. TSP has a granular form with equally sized grey color granules, making application through fertilizer spreading equipment very precise.
