When applied to the soil, a superphosphate fertilizer raises the amount of phosphorus available to plants. Regardless of type of plant, all require a healthy amount of phosphorus in order to survive. This nutrient is present in every cell of the plant, and is vital in maintaining the strength of the cell structure.ll three types of superphosphate are usually made with a naturally occurring substance called rock phosphate. While this can be applied as a fertilizer in its raw form, putting it through the chemical reactions to create other types of fertilizer has been found to make it more effective.
What is PHOSPHATE and PHOSPHITE The recognized traditional source of phosphorus has long been phosphoric acid. Phosphoric acid, when neutralized with a base, forms a salt or phosph ate . In contrast phosphite fertilizers are derived from phosphorus acid.he salt is referred to as phosph ite  as opposed to phosphate. Phosphite has one less oxygen molecule than phosphate and therefore, has a much higher degree of solubility and mobility. This unique characteristic permits phosphite to be rapidly absorbed or taken up across the membranes of plant foliage and/or roots.
