Soil form by weathering of rocks...:)
Soil forms from ground rocks and organic material like compost.
weathering results in the disintegration of rocks on a large scale. then these rocks break-up and forms soil and the soil forms the soil profile.

Phosphorus in soil can be found in several forms, including inorganic forms (such as phosphate) and organic forms (such as phospholipids in living organisms or humic substances). The availability and mobility of phosphorus in soil is influenced by its form and interaction with soil particles.
