Features of Double Super Phosphate

• DSP is one of  forms of phosphate
• DSP supplies sulphate sulphur, one of the other important nutrients in all soils
• DSP supplies calcium
• The ratio of P and S suits many crop and pasture needs
• Both the P and S are in readily available forms
• DSP can be blended with other products to make a range of products
• DSP can be stored easily for long periods, without taking up moisture
• DSP contains calcium and sulphur (mostly as gypsum) and helps keep soil in good shape by maintaining soil structure
• DSP provides a balance of P, S and Ca that mimics pasture growth requirements and is the best balanced P, S, & Ca fertiliser for Australian pastures 
• DSP is a low analysis product, more granules means more point sources of P for soil contact. (better spatial distribution)
