Using the "Statistical Yearbooks of Korean forestry", we assessed the uptake of nitrogen and base cations by Korean forest. Combined amount of base cations uptake by forest tress during its growth and that of at the time of harvest reached to 1,034 eq/ha/yr. The base cations uptake in the range of 900 ~ 1,100 eq/ha/yr occupied approximately 48.6% out of total. Coniferous forest in the range of 170 ~ 200 eq/ha/yr was 59.9%, deciduous forest in the range of 430 ~ 530 eq/ha/yr was 42.6%, and mixed forest in the range of 270 ~ 370 eq/ha/yr was 35.7% out of total. Deciduous forest recorded higher uptake rate of nitrogen and base cation than coniferous forest in Korea. Combined amounts of nitrogen uptake by forest tress during growth and that at the time of forest, was 1,108 eq/ha/yr and nitrogen uptake was in the range of 1,000 ~ 1,200 eq/ha/yr, Within Korea, forest with nitrogen uptake in the range of 1,000 ~ 1,200 eq/ha/yr account for 45.7% of the entire country. Locations in the range of 320 ~ 390 eq/ha/yr occupied 43.9% of all coniferous forest while deciduous forest in the range of 470 ~ 570 eq/ha/yr was 40.4% of total deciduous forest. As for mixed forest in the range of 270 ~ 370 eq/ha/yr, it occupied 35.9% of all mixed forest of Korea.
