To elucidate a part of phosphorus cycle and the nutritional status of phosphorus, the degradation rates of organic phosphate by phosphatase activity (PA), were studied at the water column of Lake Soyang, from March 1990 to April 1991. Phosphatase activity showed the range of 1-2200 nM/l/hr. Its maximum value was recorded on August and minimum during October and November. The PA and chlorophyll a values showed high correlation coefficient (0.69), and the values of specific activity was highest during Winter, 45-122 nM/hr/µg chl.a, and lowest on October, 2 nM/hr/µg chl.a. The values of PA and bioavailable dissolved inorganic phosphate (DIP) showed negative correlation in surface water. During destratification period (Oct. and Nov. 1990), the values of PA were about 1/240 times lower than those during August albeit high concentration of chlorophyll a (1.7-7.2 mg/m³). Such results seem to be caused by DIP supply from the metalimnion, hypolimnion and sediment. With these results, phosphate was sufficient to sustain the biomass in Autumn, and internal loading of phosphate should accelerate the eutrophication in Lake Soyang.
