SSP, also known as ordinary calcium phosphate, referred to as calcium, is a phosphate fertilizer directly produced by the decomposition of phosphate rock with sulfuric acid.
The main useful component is calcium hydrate hydrate hydrate Ca(H2PO4)2·H2O and a small amount of free phosphoric acid, and also contains anhydrous calcium sulphate component (useful for sulphur-depleted soils).
Superphosphate contains pp. 514% to 20% (80% to 95% of which is soluble in water) and is a water-soluble quick-acting phosphate fertilizer. Gray or off-white powder (or granules), which can be directly used as a phosphate fertilizer.
It can also be used as a compound fertilizer.
Feature and Function of calcium superphosphate:
- Supply Phosphorus, calcium, sulfur elements to Plant.
- Improve Alkaline soils.
- Can be used as basic fertilizer, top dressing, or Foliar Spray.
- Mixed with nitrogen fertilizer, calcium superphosphate has nitrogen fixation and reduces the loss of nitrogen, promote germination of plants, root length, branching, strong and maturity.
- Can be used as raw material for the production of composite/mixed fertilizer.
- Widely used in rice, wheat, corn, sorghum, cotton, fruits, vegetables, and other food crops and cash crops.
- SSP is one of the forms of phosphate
- SSP supplies sulphate sulphur, 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
- SSP provides a balance of P, S, and Ca that mimics pasture growth requirements and is the best-balanced P, S, & Ca fertilizer for Australian pastures
- SSP is a low analysis product, more granules mean more point sources of P for soil contact.
