Phosphorus is actually present in the soil naturally, but it is very hard to get it moving into your plants. The plant needs to be in direct contact with a phosphate to be able to make use of it. So, we need to add our own. The sources of Phosphorus we most readily use are aged manures and "meals" like bone meal or fish meal and rock ...

5.6 Phosphorus | Monitoring & Assessment | US EPA
Phosphorus cycles through the environment, changing form as it does so (Fig. 5.12). Aquatic plants take in dissolved inorganic phosphorus and convert it to organic phosphorus as it becomes part of their tissues. Animals get the organic phosphorus they need by eating either aquatic plants, other animals, or decomposing plant and animal material.

Soil phosphorus availability and lime: more than just pH ...
Plants can't do without phosphorus. But there is often a 'withdrawal limit' on how much phosphorus they can get from the soil. That's because phosphorus in soils is often in forms that plants can't take up. That affects how healthy and productive the plants can be. One influence on phosphorus availability is the soil's pH level.

Understanding Phosphorus Behavior in Soils
Phosphorus is absorbed by plants in the orthophosphate form, generally as H 2 PO 4- or HPO 42-. The amounts of these ions in the soil solution are determined by soil pH (Figure 1). At pH 7.2, there are approximately equal amounts of these two forms in solution. Maximum solubility of calcium phosphate minerals occurs at about the same pH ...
