Abstract
I The decrease of soil-moisture is shown by the following formula.<br>y=ae-logX y: percent of soil-moisture content<br>a: field water capacity<br>X: number of days with no-rain<br>b: constant<br>II The ratio of decrease of soil-water was calculated for the 1st, 5th and the 10th of every month. In a resalt of the caluclation, it was found that the ratis of the decrease was maximum in February and minimum in October, and that it was maximum at the surface of the soil (Ocm level on the ground, and a remarkable decrease did not existed near the layer with 5cm level under ground.<br>III The diagram of Isohydric line shows that the decrease of soil-water is remarkable near the surface of the soil and sometime the soil-moisture at the depth of 10cm under ground increase due to the movement of water contained in the dedper layer.<br>IV. In the diagram with vertical section for dry-season the decrease of soil-water during the dry season is remarkable at layer between the surface and 6-7cm under ground.
