Because feed phosphates are mostly produced from rock phosphate, feed phosphates have impurities that contain minerals other than P. Concentrations of P in feed phosphates range from 14.8% (MgP) to 25.7% (MSP). The standardized total tract digestibility (STTD) of P in pigs ranges from 71% (TCP) to 95% (MSP). The STTD of Ca …

In order for rock phosphate to become plant available, the acidity of the soil solution must dissolve the P into a plant-available inorganic P. Therefore, check the pH of your soil prior to applying rock phosphate as your P source. Bone meal is comprised primarily of bones and has a concentration of 330 lbs P 2 O 5 per ton of material. Bone ...

Rock phosphate is a byproduct of rock mining. It has a high phosphorus content and is used to increase the fertility of soils and as a substitute for bone meal. It is particularly good for planting bulbs and other flowering plants. Rock phosphate has an NPK ratio of 0-3-0, according to OrganicGardenInfo. It releases phosphorus very slowly into ...
To use soft rock phosphate, incorporate it into your soil prior to planting, or apply in the planting hole for transplants and when planting trees. For established landscaping, lawns, and trees, top dress the CalPhos and rake it into the soil, or apply after aerating. The better you can incorporate it into the root zone, the better your results ...
Phosphate Rock. Table of Contents. Apatite, the most abundant crystalline phosphate mineral, is found in igneous rocks and probably is the primary origin of all other phosphates, whether mineral or organic. Its chemical formula may be expressed as Ca5 (Cl,F) (PO4)3. The chlorine may be replaced almost entirely by the fluorine.
Tricalcium phosphate is usually natural and allowed when derived from phosphate rock or bone meal. Most rock phosphate on the market is in the form of tricalcium phosphate and comes from apatite or bone ash. However, tricalcium phosphate is sometimes synthesized. Synthetic calcium phosphate is not allowed as a fertilizer in organic production.
