Litter impacts on soil chemical properties and varies in tree scale. The mixed effects of litter and slope were evaluated on soil chemical properties in two coniferous plantations, Cryptomeria japonica and Chamaecyparis obtusa, pre- and post-harvest areas . Soil chemical properties altered in post-harvest areas that related to litter availability and differences between two species (Cr. japonica/Ch. obtusa) in the same slope. Remained litter maintained soil Ca²⁺ and increased soil pH in the downslope of Cr. japonica stumps. Eroded litter had least influences on soil cations while total nitrogen started to decrease vertically in either side of Ch. obtusa stumps. Although soil chemical properties are complex under growing tree in the slope areas, the supplied litter seemed to play an important role to maintain soil chemical properties after one-year logging.
