Soluble unreactive phosphorusDefinition (http://www.secchidipin.org/Phosphorus.htm) This phosphorus fraction contains filterable phosphorus forms that do not react with the phosphorus reagents under the time and conditions of the test. It is measured as the difference between soluble phosphorus (SP) and Soluble Reactive Phosphorus (SRP). The compounds in the SUP fraction are organic forms of phosphorus and chains of inorganic phosphorus molecules termed polyphosphates. The size of this fraction relative to the other phosphorus fractions is highly dependent on the type of filter used to separate the soluble from particulate fractions.
