High-Concentration Phosphate Fertilizer for Broadcast, Band & Fertigation Use

Triple Super Phosphate (TSP) 0-46-0 is the highest-phosphorus dry fertilizer available without nitrogen — delivering 46% P₂O₅ with more than 90% water-soluble orthophosphate for rapid plant uptake. It also supplies 15% calcium (Ca) as monocalcium phosphate, making it a dual-nutrient source for phosphorus- and calcium-deficient soils. Sold in a 50 lb bag, TSP is a staple for broadcast applications, concentrated banding, and citrate-solution foliar programs.

Phosphorus drives root development, energy transfer (ATP), and flowering. TSP’s high water solubility means phosphate moves quickly into the root zone after application — critical for early-season establishment and transplant recovery. The calcium component supports cell wall strength and reduces blossom-end rot risk in susceptible crops.

Guaranteed Analysis

• Available Phosphate (P₂O₅): 46%
• Water-soluble P₂O₅: >90%
• Calcium (Ca): 15%
• Derived from: Monocalcium Phosphate

Application Methods

• Broadcast: Apply to soil surface and incorporate; consult a certified crop advisor for crop-specific rates
• Band: Apply in a concentrated band beneath the soil surface at planting
• Foliar (citrate solution): Dissolve in citrate solution per label recommendations; suitable for leguminous crops including beans and alfalfa

Key Features

• 46% P₂O₅ — highest phosphorus concentration of any nitrogen-free dry fertilizer
