1. FEATURES
SSP is one of forms of phosphate
SSP supplies sulphate, one of the other important nutrients in all soils
SSP supplies calcium
The ratio of P and S suits many crop and pasture needs
Both the P and S are in readily available forms
SSP can be blended with other products to make a range of products
SSP can be stored easily for long periods, without taking up moisture
SSP contains calcium and sulphur (mostly as gypsum) and helps keep soil in good shape by maintaining soil structure
2. MANUFACTURE
Single Super Phosphate is produced by reacting naturally occurring Rock Phosphate with Sulphuric Acid. This process converts insoluble phosphates into forms more readily available to plants.
Phosphate Rock + Sulphuric Acid = Single Super Phosphate
Impact Fertilisers' SSP manufacturing process uses blends of various Phosphate Rock sources.
Critical steps in the process include:
Grinding the Phosphate Rock (PR) to the correct size
Accurately metering the PR, Sulphuric Acid, and water
Mixing together thoroughly
Time for the reactions to occur
The reacted material is fed into a granulation drum and across a screening process to produce granulated Single Super Phosphate.
The Single Super Phosphate is then stored for a period of weeks to allow further reactions to occur within the product to maximise the proportion of available Phosphate in the commercial product.
