Abstract
Seasonal variation of the soil microorganisms involved in carbon and nitrogen mineralization and major soil nutrients such as nitrogen and phosphorus were investigated in a 30-year-old Quercus mongolica Fisch. stand and in 8-, 18-and 28-year-old Pinus koraiensis S. et Z. plantations following clearcut of Quercus mongolica Fisch. stand and in 8-. 18-and 28-year-old Pinus koruiensis S. et Z. plantations following clearcut of
Quercus rnongolica Fisch. This study was conducted at the Seoul National University Forests placed
along Mt. Taewha located in Sanglim-lee, Docheok-myon, Kwangju-gun, Kyonggido. Korea.
Seasonal variation in soil physicochemical conditions was greatly fluctuated at 8-year-old Pinus
koruiensis plantation than at other stands due to clearcutting. The factors which were significantly
different among those stands were contents of total N, C, P, soluble salts, moisture and ammoniun N.
and pH. Total nitrogen and available phosphorus gradually decreased after clearcutting, but were
recovered after about 20 years. Contents of moisture, ammonium N, soluble salts and total carbon
were reduced by the clearcut, but the maturation of the stand improved soil conditions at all of the
stands. The populations of soil microorganisms involved in carbon and nitrogen mineralization were not
significantly changed by the clearcut.
Thus. the establishment of P. koruiensis plantation following clearcut of Q. mongolicu changed total
nitrogen and carbon contents, but did not disturb greatly the forest soil condition.
