WebSome phosphorus is present as part of soil organic matter and becomes available to plants as the organic matter decomposes. Most inorganic soil phosphorus is bound tightly to the surface of soil minerals (e.g., iron and aluminum oxides). Warm, moist, well-aerated soils at a pH level of about 6.5 optimize the release of both of these forms. ... WebSIMPLIFIED COLORIMETRIC DETERMINATION OF SOIL ORGANIC MATTER.
