We made an investigation of soil erosion control in Hokkaido as the work of land conservation. Especially we tried the water sprinkling test so that the technical importance of various green belt width was decided in place of the terrace channel. Although the terrace channel has been emphasized as the best soil erosion control for a long time in Japan, recently it has became a serious problem and the terrace is reexamined because of the large field lot modification and farm mechanization. In the results of the experiment, it was clearly noted that the ground surface flow is decreased by the green belt as well as the terrace channel. As in bare ground, the loss of soil by ground surface flow is increased proportion to the slope incline and it is intercepted by the filtering properties of the green belt. Still further, we can not overlook the effect of subsoil break on soil erosion control, because the ground surface flow and loss of soil are decreased by it.
