A comparison of five methods differing in principle and complexity showed that one involving sequential extraction with hot HCl and cold and hot NaOH was best for the routine determination of organic phosphorus in lake sediment. Total organic phosphorus ranged from 23 to 147 mg P/100 g oven‐dried sediments and from 8 to 63% of the total phosphorus.
