A simple water collector was devised for monitoring of the stemflow effect on soil ecosystem. The collector catches the stemflow and reciprocal cup gives the flow rate as pulse count. The stemflow is then divided into two sections, one with ion exchange resin and the other with grass beads. Both cation exchange resin and anion exchange resin were mixed and the beads were used as a control. Stemflow in a Cryptomeria japonica forest was collected and introduced to the soil microcosm after passing ion exchange resin or grass beads. The resin treatment changed the water quality; NO_3^-, SO_4^<2->, and Cl^- concentrations were reduced and pH was slightly decreased. Soil respiration of the microcosm was slightly enhanced by the grass beads treatment than by the resin treatment.
