THE EFFECT OF TWO NONIONIC SURFACTANTS ON AGGREGATE STABILITY OF SOILS

THE EFFECT OF TWO NONIONIC SURFACTANTS, SOIL PENETRANT AND AQUA GRO ON THE AGGREGATE STABILITY OF TWO HYDROPHILIC SOIL SYSTEMS, AND ONE HYDROPHOBIC SOIL SYSTEM WAS STUDIED. TWO SETS OF EXPERIMENTS WERE CONDUCTED TO SIMULATE TWO DIFFERENT FIELD CONDITIONS. IN THE FIRST SET OF EXPERIMENTS THE AGGREGATE STABILITY OF SOILS WAS DETERMINED IN SOLUTIONS OF DIFFERENT SURFACTANT CONCENTRATIONS. IN THE SECOND SET, THE AGGREGATE STABILITY OF SOILS PRETREATED SEPARATELY WITH FREE SURFACTANT SOLUTIONS WAS DETERMINED IN DISTILLED WATER. RESULTS SHOW THAT THE APPLICATION OF SURFACTANT EITHER BEFORE OR WITH THE IRRIGATION WATER WILL DECREASE THE AGGREGATE STABILITY OF THE HYDROPHOBIC SOILS. IN THE CASE OF THE HYDROPHILIC SOILS THE APPLICATION OF SURFACTANT WITH IRRIGATION WATER WOULD DECREASE THE STABILITY OF THE SYSTEM, YET ITS RESIDUAL EFFECT MIGHT PROMOTE THE STABILITY OF THE SOIL IN SURFACTANT-FREE IRRIGATION WATER.
