Triple Superphosphate

(TSP) 0-21-0-1

1. FEATURES

T.S.P. is one of the cheapest sources of phosphorus available. It can be used in most situations where only phosphorus is required, or in a wide range of blends.

2. ANALYSIS

3. MANUFACTURE

Triple superphosphate is manufactured in a two stage process.
First, sulfuric acid is reacted with phosphate rock, to produce phosphoric acid. Gypsum is a by-product of the stage and is removed.
Secondly, the phosphoric acid is reacted with phosphate rock resulting in triple superphosphate.

4. USES

• As a low cost source of Phosphorus, TSP is the main substitute for single superphosphate in cropping blends.
• It is used mainly in blends with DAP and MOP
• Source of phosphorus in situations where no nitrogen is required e.g. Good fallow after clover dominant pasture.
• In horticultural blends where the phosphorus content needs boosting.

5. PHYSICAL PROPERTIES

Sizing 95% in the 2 – 4 mm range
Bulk density 1.10 – 1.20 t/m3
Angle of response 31-33°

6. HANDLING

• TSP has excellent physical qualities. It stores, handles and flows through all types of equipment extremely well
• Does not take up moisture in storage or in the field
• Spread very evenly
• TSP flows significantly quicker than other fertilisers, approximately 15 to 20% faster than DAP so care must be taken in calibration, before sowing.

7. RESTRICTIONS

• Do not mix with urea as the fertilisers will react together and become wet*
• Low in sulphur

* check with your local depot on suitability for blending.
