  • Patent number: 4651468
    Abstract: A method and apparatus for providing natural fertilization and irrigation is designed to preserve the osmotic, chemical and electric natural equilibrium of plants. More specifically, the method and apparatus relies upon negative sap pressure within plants which facilitates the providing of water, fertilizers, gases, and other chemicals in the exact amounts needed by the plants. The apparatus includes a porous ceramic implant in a plant stem with liquid being provided by capillary action to the implant from an external source. The plant will draw liquid through the porous implant in proportion to the amount needed by the plant. A passive solar distiller also forms a part of the method and apparatus of the invention.
