Abstract
A method and apparatus for treatment of land surfaces is disclosed. The land surface is imprinted by means of imprint capsules of alternating geometries--one being a water-runoff-directing geometry; the other, a water-infiltration-enhancing geometry. The method prevents water runoff and enhances water infiltration into the soil in areas where high moisture levels would be desirable, such as in seed beds and at the base of growing plants.
