| Research Abstract |
The objectives of this study are to evaluate the effect of the crop root on the soil water conductivity and retentivity and to quantify the water consumption in the crop field considering the root effect on the soil physical properties. The relationship between root structure and the soil physical properties were clarified. A simulation model was introduced to quantify the water consumption considering the crop root effect on the soil physical properties. The model accuracy was verified by the field observation.
