Super Triple Phosphate (TSP) Fertilizer

Super Triple Phosphate (TSP) is one of the most concentrated dry phosphorus fertilizers available, delivering up to 46% P₂O₅ with over 90% water solubility for rapid root uptake. With 15% calcium included, TSP supports both phosphorus and calcium nutrition in a single application — ideal for pre-plant incorporation, broadcast, or banded placement.

Key Features

• High phosphorus concentration — 0-45-0 and 0-46-0 formulas available; more P per pound than most granular sources
• 90%+ water-soluble phosphorus — fast availability for root uptake and early plant establishment
• 15% calcium — supports cell wall development and secondary nutrition alongside phosphorus
• Versatile application — broadcast, soil incorporation, or concentrated band below seed
• Compatible with fertigation programs — dissolves readily for liquid feed applications

Recommended Crops & Uses

Ideal for leguminous crops, row crops, vegetables, and specialty crops with high phosphorus demand. Suitable for pre-plant soil incorporation and foliar applications with a citrate solution.

Important Note

Super Triple Phosphate is a conventional fertilizer and is not approved for use in certified organic agriculture.
