  • Patent number: 6688038
    Abstract: A mulch composition having extended moisture retention time and a method for use thereof are provided. In a first preferred embodiment of the present invention, a hydro mix moisturizing agent is added to a seeded mulch. The preferred embodiment comprises 93.95% of water, 5.85% of mulch, and 0.2% moisturizing agent by weight as a percentage of the weight of the water used, and fertilizer and seed in any selected amounts. In this preferred embodiment, the moisturizing agent comprises a cellulose gum, a cross-linker, and a surfactant. The moisturizing agent retains water in the mulch composition and releases water into the soil surface at a controlled rate while binding together the mulch composition. Moisture is retained for a longer amount of time than the prior art mulch compositions to promote maximum seed germination. The mulch composition according to the present invention additionally provides effective dust and erosion control properties.

  • Patent number: 6138408
    Abstract: A system and method are provided for controllably delivering water from a moisturizing agent to plant tissue. The angled insertion end of a delivery tube is placed in the soil in close proximity to the root system of a plant. An insert containing moisturizing agent is opened at an end to expose the moisturizing agent and then placed through the receiving end of the delivery tube and into the hollow bore thereof. A cap is then removably placed over the receiving end to seal the insert within the hollow bore of the delivery tube, thereby reducing loss of moisture to evaporation and preventing foreign matter or insects from migrating into the tube. An exhausted insert is replaced by removing the cap, withdrawing the empty insert, and placing a new insert within the hollow bore of the delivery tube. Alternatively, moisturizing agent can be directly injected into the delivery tube, for example, from a tank or canister.
