Through experiments of the action of electromagnetic field to soil column, it is discovered that water potential of soil can be increased greatly by the action of alternative ' electric field, and some principles between outside electric field and the water potential of soil etc. are gained. The experiments also indicate that water potential of soil can return to its origenal value when the electric field is cancelled. These results show that the soil structure acted with alternative electric field has not been destroyed, and there is no'pollution'of soil to be found. And thus, this discovery presents a new way of using soil water in arid and semiarid areas.
