Product Overview
Triple Super Phosphate (TSP) with 46% P₂O₅ is the most concentrated straight phosphorus fertilizer — providing phosphorus without nitrogen, making it the ideal choice for custom blending where independent P adjustment is required. Unlike DAP and MAP that combine P with N, TSP allows agronomists and blending plants to precisely control the N:P ratio in compound formulations. The granular form ensures uniform distribution and excellent handling characteristics in mechanical spreading and blending equipment. A staple product for Australian, Brazilian, and Southeast Asian agriculture where phosphorus-dominant basal programs are standard practice.
How Triple Super Phosphate (TSP) Works
TSP is produced by acidulating phosphate rock with phosphoric acid, converting insoluble rock phosphate to water-soluble monocalcium phosphate [Ca(H₂PO₄)₂]. With ≥85% water-soluble P₂O₅, phosphorus is immediately available to plant roots upon soil moisture contact. The neutral reaction (unlike DAP’s alkaline or MAP’s acidic effect) makes TSP the most versatile P source across all soil pH ranges. The calcium content (~15% CaO) provides supplemental calcium nutrition — beneficial for calcium-demanding crops grown on acidic soils.
Key Benefits
Application Guide
Basal application: apply 100-300 kg/ha at planting, incorporated into the root zone. For phosphorus-deficient soils: apply 200-300 kg/ha. For maintenance P: 100-150 kg/ha based on soil test P. Blending: mix with urea, AS, and MOP for custom NPK ratios. Banding: 50-100 kg/ha placed near the seed for targeted P placement. Not suitable for fertigation — water solubility is insufficient for drip systems. Use MAP for fertigation P needs.
Ideal For
Storage & Handling
Store in dry conditions on pallets. TSP is one of the most stable fertilizer types — low hygroscopicity and no fire risk. Shelf life: 36 months. Compatible with all blending and spreading equipment. The granular form resists caking and segregation during storage and transport.
