| Estimation of the annual net production, nitrogen (N) and base cation (BC£½K, Mg, Ca) uptake by stocked forests in South Korea has been done with national statistical data of forestry from 1995 to 1999. The annual net production of stems and branches was about 1.8 ton DM ha/sup -1/ yr/sup -1/. The net productivity of deciduous forests was higher than that of coniferous forests. Total net production of the stocked forests from the whole stocked area of South Korea of 6.246¡¿10/sup 6/ ha, was about 1.13¡¿10/sup 7 ton DM/yr, and the total harvested biomass obtained from timber production data in 1999, was estimated about 6.1¡¿105 ton DM/yr that was equivalent to 98 kg DM ha/sup -1/ yr/sup -1/f. Net growth uptake of N and BC were 350 mol ha/sup -1/ yr/sup -1/ and 296 mol ha/sup -1/ yr/sup -1/ respectively, and the content of N and BC contained in the harvested biomass were 20 mol ha/sup -1/ yr/sup -1/ and 16 mol ha/sup -1/ yr/sup -1/ respectively. Net uptake of N was higher than that of BC. Total net uptake of N and BC from growth and harvest by stocked forests in South Korea were 2.309¡¿10/sup 9/ mol/yr and 1.953¡¿10/sup 9 mol/yr respectively. |
