SSP

Single superphosphate (CaP 20:18)

Single superphosphate (SSP) was the first commercial mineral fertilizer and it led to the development of the modern plant nutrient industry. This material was once the most commonly used fertilizer, but other phosphorus (P) fertilizers have largely replaced SSP because of its relatively low P content. SSP can easily be produced on a small scale to meet regional needs. Since SSP contains both monocalcium phosphate (MCP, also called calcium dihydrogen phosphate) and gypsum, no problems arise with phosphogypsum byproduct disposal unlike the manufacture of other common P fertilizers.

    Application

  • Period: Autumn, Spring
  • Method: At the time of Sowing
  • Soils: sulfur deficient soils

    Advantages

  • SSP is one of the cheapest forms of phosphate & Supplies sulfate sulfur and calcium
  • The ratio of phosphorus and sulfur suits many crop and pasture needs. Both the phosphorus and sulfur are in readily available forms.
  • It can be blended with other fertilizer products (except Urea & DAP).
  • It can be stored easily for long periods, without taking up moisture.
  • It contains calcium and sulfur (mostly as gypsum) and helps keep soil in good shape by maintaining soil structure. SSP provides a balance of P, S, and Ca that mimics pasture growth requirements and is the best-balanced P, S, and Ca fertilizer for Australian pastures.
