Abstract
Water transmission and storage characteristics were examined on undisturbed soil, nonsodic spoil, sodic spoil and topsoil over sodic spoil sites. Bulk density, particle size analysis and soil water content both before and after water application were determined. Restrictions to water movement within the profile were found on the undisturbed and topsoil over sodic spoil areas. Infiltration on the sodic spoil site was minimal due to a disperse surface condition. Saturated hydraulic conductivity of 1.5 inches per hour was measured at the nonsodic spoil location. Identification of soil properties on reclaimed sites to a depth of up to 10 feet may be necessary to determine water transmission and storage characteristics.
