1 Features and benefits


Can be 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 Manufacture


Triple Superphosphate is manufactured in a two stage process. First, sulphuric 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.


3 Uses


 As a low cost source of phosphorus, TSP is the main substitute for Single Superphosphate in cropping blends.

The product is used mainly in blends with DAP and MOP.

It is a source of phosphorus in situations where no nitrogen is required, for example, good fallow after clover dominant pasture.

It is also used in horticultural blends where the phosphorus content needs boosting.

4 Stoarge and 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.

5 Restrictions


Do not mix with urea as the fertilisers will react together and become wet. Please check with your local depot on suitability for blending.

Do not store in silos.
