EFFECT OF CHEMICALS UPON INFILTRATION OF WATER INTO SOILS

摘要

The possibility of increasing the infiltration of water into soils by the addition of chemicals was investigated. Beneficial ef¬fects were obtained by adjusting the influent to a concentration of 1 ppm Separan 2610;10 ppm Dow-Corning Ant 1 foam A, a common antifoam agent;or 0.l% by volume of Aerosol 0.Ta wetting agent.nThe infiltration also was increased if "Krilium" ** was mixed intimately with the upper layer of soil in a column before adding water.
