The Phosphorus Fractionation Sediment Test is a laboratory analysis that identifies how phosphorus is stored in sediments and how likely it is to be released into the water column. By separating total phosphorus into fractions with different mobility and bioavailability, the test helps assess internal nutrient loading, algal bloom risk, and informs targeted lake and reservoir management decisions.
