Phosphorus has more than one extraction method, and interpretation varies depending on the type of extractor used. The dynamics of phosphorus is associated with many factors, such as the degree of soil weathering, source material, activity of soil organisms, etc. All of this also modifies the availability of this nutrient for plants. In soil, organic and inorganic phosphorus (P) can also be classified as labile and non-labile. The labile fraction is formed by compounds that are capable of replenishing P in the soil solution when it is absorbed by plants or microorganisms.
