In order to make a mechanization possible in citrus orchard in slope land, the orchard path construction by a simple soil stabilization technique was developed.
1) The minimum width of orchard path arranged with a space of 5 to 10 meters in contour was about 80 centimeters from both sides of the trafficability of the transport vehicles and a present state of sloped land. The density of orchard path was amounted to 100 to 200 meters per 10 ares.
2) The surface stabilization technique holding together cement, special setting material (Soiler) with on-the-spot soil was considered to be enough for farm roads, which may be cheep and easy to construct. The optimum mixing rate was 13% of cement and 0.3% of setting material.
3) This simple soil stabilization technique by farmers using such as machines like the small size buckhoe, the spreader and the rotary tiller was so simple and less expensive.
