Fractionation of phosphorus and nitrogen loadings from a Northern Ireland fish farm
Over a 1-year period, the composition of the total phosphorus loading from a N. Ireland fish farm was as follows: soluble reactive phosphorus (SRP) 60.0%, soluble unreactive phosphorus (SUP) 10.0% and particulate phosphorus (PP) 30.0%. By comparison, the fractions of the total nitrogen loading were:...
