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.
