We investigated soil erosion control on an inclined field by tilling a green belt and breaking the subsoil in the field. The results of the experiment indicated that the surface run-off coefficient was considerably increased by making the width of the green belt less than 6 meters, and the surface run-off was decreased to about 50% by breaking the subsoil with a pan breaker which allowed the water to flow away. Next, the results indicated that when the surface water flowed through the green belt, the quantity of mud contained in it decreased considerably by the filtering properties of the green belt. The conclusion obtained is that, when we till a green belt 6-10 meters in minimum width and break the subsoil, we can double the interval of terrace channeles which was formerly set up to control soil erosion on an inclined field.
