7 - 9.5% P; 16 to 22% P2O5 this is the phosphorous content in superphosphate
Phosphates are natural minerals; but phosphatic fertilizers are products of the chemical industry.
Sulfur is a solid nonmetal which is an important element in the fertiliser super phosphate
The solubility of Ca(H2PO4)2·H2O is approx. 20 g/L at approx. room temperature.

7 - 9.5% P; 16 to 22% P2O5 this is the phosphorous content in superphosphate
phosphoric acid, triple superphosphate, ammonium phosphate, and superphosphate
in a 1 % solution by weight superphosphate has a pH of 3 so it will lower the pH of the environment it is introduced to ie. a pasture.
You add superphosphate to the soil.
A superphosphate is a type of fertilizer that is made by treating phosphate rock with sulfuric or phosphoric acid. The three types of superphosphates are single, dicalcium and triple phosphate.
Superphosphate of lime is more commonly used as an acidic fertilizer compared to ammonium sulfate. Superphosphate of lime has a lower pH level, which helps in making soil more acidic to improve nutrient availability to plants.
The chemical formula of phosphorite used in superphosphate fertilizer is generally Ca(H2PO4)2, which is a type of phosphate rock. Superphosphate fertilizer is created by treating phosphorite with sulfuric acid to form water-soluble phosphate compounds that can be easily taken up by plants.
Ca(H2PO4)2(s)+2CaSO4.2H2O(s)
sulphuric acid
single super phosphate or superphosphate of lime, Ca(H 2 PO 4 ) 2 , is a compound produced by treating rock phosphate with sulfuric acid or phosphoric acid, or a mixture of the two. It is the principal carrier of phosphate, the form of phosphorus usable by plants, and is one of the world's most important fertilizers. Ordinary superphosphate contains about 20% available phosphate; double superphosphate (also called treble superphosphate) contains 40%-50% available phosphate.
Phosphorus can be added to soil through the application of phosphorus-containing fertilizers. These fertilizers can be inorganic (such as superphosphate or triple superphosphate) or organic (such as bone meal or manure). The phosphorus from these sources becomes available to plants as they grow and absorb it from the soil.
Phosphates are natural minerals; but phosphatic fertilizers are products of the chemical industry.
