An analysis of moisture in the soil and the physical explanations of process of infiltration is presented. Examples of data are drawn from USDA Bulletin No. 729, and from well scattered sites over the State of Ohio. Infiltration enters the soil directly through capillary action in all directions and in some cases through gravity channels. This capillary action effects the root zone of plants and is f most interest to the agronomists, while the gravity water, some of which may supply the capillary action, is of most interest to the hydrologist. From this source comes the ground water supplies, and largely soil moisture from precipitation. Infiltration rates are dependent on both. Graphs are exhibited to show effects of capillary absorption and the rate of absorption. Computed data are shown in tables.Discussion by several engineers and soil physicists are included with the references.
