Abstract
A granular or plate-like calcium aluminum silicate layer stores water beneath fertile soil. The silicate material may be coated with fertilizer or chemicals and may be shipped and installed within a wrapping, at least one surface of which is moisture pervious. A fleece-like material may form the pervious surface. A silicate container with a perforated cover and sidewalls fits within a planter. A filler pipe extends through the soil into the container. The silicate material may be mixed with the fertile soil.
Claims3
A moisture reservoir for plants comprised of a soil and water impermeable first layer, a second layer of expanded aluminum silicate on said first layer, and means in said second layer for applying moisture thereto, a third layer of a mixture of soil and expanded aluminum silicate on said second layer, and a fourth layer of soil on said third layer.
A moisture reservoir for plants comprised of a mass of aluminum silicate surrounded on its sides and bottom by a water and soil impervious material, fibrous wicking material across the top of said mass, a soil layer on said wicking material, and a filling pipe beginning at a point above said soil layer, extending therethrough, and terminating adjacent said wicking material.
