Abstract
When dealing with bed soil for planting treatment, one needs to be cautious of the physical soil properties. Since the coefficient of permeability, the suction and the hardness index of the bed soil etc. change with the soil densities, it becomes important to control the density in compaction. In this examination, controling the density of the model bed soil by changing compaction energy and a variety of physical properties of the model bed soil were experimentally evaluated.
