- The content of nutrients such as organic carbon, nitrogen, phosphorus andpotassium accumulated on soil layers in Quercus mongolica forest of Mt. SongnisanNational Park located at central part of Korea was measured, and then the decom-position constants and decay times of the nutrients were also calculated by thenegative coefficience model(Olson, 1963). The quantities of organic carbon of L-layer,F-layer, H -layer and A 1-layer of the forest stand were 231.25 g m-2, 291.50 g m-2, 166.91g m-2 and 174.51 g m-2, respectively. The content of organic carbon and nitrogencontained in L -layer and F -layer showed large quantity than those of other layers.The large amount of phosphorus and potassium was observed at the H -layer and A 1-layer. On the other hand, the decomposition constants(k) of soil organic matter were aspotassium (k = 0.0934) and the decay times needed to 99% decomposition of nutrients insoil organic matter were as follows: that is, organic carbon, nitrogen, phosphorus andpotassium was 13.94 years, 15.18 years, 24.79 years, and 55.11 years, respectively. Bythe application of Turbo Pascal Program on the inflowed and outflowed nutrients tothe forest stand, 87.67% (714.84 g m-2) of organic carbon inflowed was decomposed and81.62% (1,594.62 g m-2) of organic carbon accumulated was decomposed. And 84.98% ofnitrogen inflowed was decomposed and 70.26% of nitrogen accumulated was alsodecayed. 50.00% of phosphorus input and 40.31% of potassium input were decomposed,and 38.46% of phosphorus and 33.03% of potassium accumulated were also decayed,respectively. Therefore, it is suggested that Quercus mongolica forest surveyed in thepresent study is maintaining in steady state because input and output amounts ofnutrients is shown a similar pattern.
