The objectives of this study were to compare nutrient natural input between thinned and unthinned natural hardwood stands at Mt. Joongwang, Pyongchang-gun, Gangwon-do. Throughfall, stemflow, Alayer and B-layer soil water as well as litterfall were sampled at two-week intervals during the period of June to October from 2002 to 2004. The amount of rainfall interception in thinned and unthinned natural hardwood stands was as 12% and 18%, respectively. The results indicated that there was no difference in annual nutrient input by rainfall between thinned and unthinned stands. Na+, Cl- and SO4 2- concentrations of A-layer soil water in the unthinned stand were higher than those in the thinned stand. In the B-layer soil water, Ca2+, Cl-, NO3 - and SO4 2- concentrations in the unthinned stand were higher than those in thinned stand. Mean annual litterfall input was 2,706 kg ha-1 in unthinned stand and 2,589 kg ha-1 in thinned stand. Total-N input from litterfall was 50.28 kg ha-1 yr-1 in the unthinned stand and 36.81 kg ha-1 yr-1 in the thinned stand, while there was no difference in exchangeable cation input from litterfall between thinned and unthinned stands. Thus, the difference in utrient inputs except for N by throughfall, stemflow and litterfall between the two stands was not influenced by thinning.
