| Litter production and decomposition were investigated for 2 years in the oak, Quercus acutissima, and the pitch pine, Pinus rigida, stands in the vicinity of Kongju, Chungnam Province. Litter production was measured with litter trap at monthly basis. Litterbag method was used for the measurement of litter decomposition. Litter producion continued throughout the year, but showed a peak in autumn. Second peak in May or June was caused by falling of bud scales and reproductive organs. Average litter production in the oak and the pitch pine stands were $567.1g{cdot}m^{-2}{cdot}yr^{-1};and;653.2g{cdot}m^{-2}{cdot}yr^{-1}$, respectively. Litter production in this study area were higher than those in other reports. Nutrient concentrations in litter were the highest in summer when the least litter production occurred, and the lowest in autumn when the greatest litter production occurred, except for calcium in the oak stand. Nutrient concentrations of the oak litter were higher than those in the pitch pine litter. After 1 year, % remaining mass of oak and pitch pine litter was 43.6% and 58%, respectively. After 21 months elapsed, % remaining mass of oak and pitch pine litter was 22.2% and 33.2%, respectively. |
