  • Patent number: 6701664
    Abstract: Seed tape (1) for a controlled germinating process is made of at least two paper layers (1′ and 1″) and is intended to be used while placed edgewise. Each germinating unit includes a seed (5), additives (6) and a carrier (8). Each germinating unit (1a, 1b, 1c, 1d) is formed as a planar member. The longitudinal axis of each planar member extends substantially transverse to the longitudinal direction of the tape. The additives are places in discrete locations around the seed. The seed, the additives and the carrier are adhered to the inner face of at least one paper layer (1′), which is air-permeable. A narrow stripe (10) of water-absorbing, super-absorbing polymer (SAP) is placed on the adhesive layer of at least one paper layer (1′ or 1″). The resulting seed tape is particularly suited for providing a controlled moist microclimate around the seeds during a two-step germinating process.

  • 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.

    Abstract: A method is provided for mulching an agricultural soil bed using a biodegradable protein mulch material. The method includes the preparation of a film forming solution of a film forming protein material. The film forming protein solution is then sprayed directly onto a surface of an agricultural soil bed. The solution dries to form a thin film of protein material on the surface of the agricultural soil bed. The protein material may comprise a plant protein, a milk protein, an animal protein, a whey protein, casein, an egg protein or gelatin. Following a harvest, the mulch material, which is biodegradable, may simply be plowed under.

    Abstract: A synthetic grass surface includes widely spaced rows of ribbons projecting from a flexible backing sheet. Thermal regulating means are attached to the backing sheet in the spaces between the rows of the ribbons. A relatively thick infill layer is disposed on the top of the backing sheet, thereby burying the thermal regulating means and holding the ribbons upright. The infill layer may include a growing medium for plant growth. In one embodiment, electric cables are integrated into the synthetic grass surface in order to heat the surface for de-icing or to maintain plant root warmth. In another embodiment, perforated flexible pipes are integrated into the synthetic grass surface to moisten the surface, thereby cooling the surface when the moisture evaporates. The thermal regulating system of the invention is energy-efficient and economical to install and operate.

    Abstract: A mulching structure for covering the soil around the stem of a growing plant and over the roots thereof to screen sunlight from the adjacent soil and thus minimize the growth of weeds. The mulching structure also allows water from irrigation or rain to flow therethrough to the soil. The mulching structure includes a first wall made out of a substantially impermeable material. The first wall is provided with a first wall aperture extending therethrough. The mulching structure also includes a second wall made out of a substantially impermeable material. The second wall has a second wall aperture extending therethrough. A wall spacing structure extends between the first and second walls for maintaining the latter in a spaced relationship relative to each other. The mulching structure is so configured as to allow through flow of the water between the first and second wall apertures while preventing through passage of the light rays from the first wall outer surface to the second wall outer surface.

  • Patent number: 6318021
    Abstract: A method of treating plant biomass material involves treating the material with sesquioxide mineral forming constituents to form protective coatings on surfaces of the material and to alter the bulk physical and chemical properties of the treated material. The material is treated with an aqueous solution of soluble iron and/or aluminum thus improving microbial stability and quality of the materials.

  • Patent number: 6312826
    Abstract: Biodegradable, agricultural mulches are prepared by coating paper with a cross-linked drying oil or a cross-linked, functionally modified drying oil. These mulches are inexpensive to produce, and are also water-resistant, mechanically stable and highly effective as weed barriers. The reactivities of various drying oils permit the development of a broad spectrum of coating systems and coating properties. In one embodiment of the invention, it is contemplated to complete cross-linking of coated paper in the field through either oxidative or photoinitiated processes.

  • Patent number: 6308455
    Abstract: A method and machine for changing or renewing the color and/or light reflection, transmission, and absorption characteristics of an existing layer of synthetic agricultural mulch or prolonging the usefulness of the existing mulch by applying a layer of new mulch to the pre-existing mulch in a cultivated field using heat welding/fusion or adhesive or mechanical fastening for attachment of new mulch to existing mulch and at least one blower for clearing debris from the existing mulch prior to application of new mulch, with the machine being able to be drawn by a tractor, laborer, or draft animal.

  • Patent number: 6293045
    Abstract: Mulch mat comprising an air and water-permeable, light-impermeable, open celled, composite of granular material and biodegradable fibers in a binder matrix prepared from a foam precursor. Disclosed biodegradable fibers include cellulosic fibers such as shredded wood, straw, shredded paper, wood pulp, cotton fiber, shredded corn stalks and moss; protein fibers such as hair and gelatin; and synthetic polymer such as vinyl polymer fibers and polyamide fibers. Disclosed granular material includes milled hard vegetation such as corn cob, nut shells, seed hulls, seeds, bark and gourds; soil builders such as vermiculite, perlite, sand, diatomaceous earth and gypsum; nutrients such as nitrate compounds, potassium compounds and phosphorus compounds; soil conditioners such as limestone, sulfur and iron sulfate. Useful binders include polysaccharides, polyglycosides, vegetable gums, vinyl polymers, waxes and crosslinkable oils. Useful surfactants include saponin, e.g. extract of Yucca shidigera, and amine surfactants.
