Triple Superphosphate (TSP)
- Chemical Name
- Triple Superphosphate
- Crop Segments
- High analysis phosphorus reduces freight and spreading costs compared to Single Superphosphate.
- Quality & Handling
- Nominal 2-4mm granule sizing, free flowing properties.
Bulk density 1.1 tonnes per cubic metre.
- Can be blended with most products and trace elements with the exception of Urea based products.
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.
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.
- 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. Storage 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.
- 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.
