Seed germination structure

Abstract

Abstract A permeable fabric or film, e.g., an on-woven polyolefin such as polypropylene, is treated on one side with a carrier containing seed and comprising a water-soluble material or gum, e.g., carboxymethylcellulose. A filler, e.g., subdivided cellulose and/or a fertilizer, e.g., ammonium nitrate, can be incorporated into the carrier. The other side of the fabric or film is coated with asphalt applied as a dilute emulsion wash, or the fabric can be at least partially saturated with asphalt. The thus treated fabric or film is placed seed treated side down on and can be fastened to the ground to produce accelerated seed germination and growth and to protect against erosion until a desired stand of ground cover has been grown. When degradation of the fabric or film is desired, it can be chosen to be an ultraviolet degradable material, e.g., unpigmented polypropylene. by varying the amount and/or dilution of asphalt or of asphalt emulsion or other material combined with the film or fabric selected periods of time of slope reinforcement can be obtained. A radiant heat absorbent material e.g., a dark pigment, such as carbon black, can be incorporated into the asphalt or similar wash.
