Document Summary
The most important input of phosphate is in the form of orthophosphate (po4) from erosion of sediment, runoff and plant/animal decay (most important) In an extremely unproductive lake, an important source of p can be from sediment through erosion, or from sewage waters and runoff, rocks soil etc. Weak oxidation is used to measure srp and it is filtered so it is readily available for. Strong oxidation captures both available and non-available forms of p. the p that gets. The analytical determination of phosphorus involves either weak or strong digestion and filtration or non-filtration. How are these operationally defined fractions related to bioavailable and non-available p in natural systems? algae. past the filter is bioavailable. Stuff that doesn"t get through the filter is not bioavailable. It has been commonly recognized that chlorophyll a and algal biomass is strongly correlated to total p in water.
