Mulching Patents (Class 47/9)
  • Patent number: 9481011
    Abstract: An apparatus including an air blower; a rotary airlock; a receptacle having an inner chamber supplied with a plurality of colorant particles; a water supply; and a mixing chamber. The air blower blows air into a bottom section of the rotary airlock, and the rotary airlock receives colorant particles from an output of the receptacle. A rotor shaft of the rotary airlock rotates to cause colorant particles to be transported to the bottom section of the rotary airlock. Air blown into the bottom section of the rotary airlock mixes with colorant particles transported into the bottom section of the rotary airlock to form an air and colorant particles mixture, which is blown out of a first output of the rotary airlock and combined with water to form a water, air, and colorant particles mixture, which is mixed with material in a mixing chamber. The material may be natural mulch.

  • Patent number: 9072228
    Abstract: The present invention provides a method of treating mulch by applying an adhesive composition to bulk mulch and then bagging the treated mulch before the adhesive cures. The bagged mulch is later transported to a desired location and arranged into a mulch bed, and the adhesive cures by exposure to air and sunlight, thereby holding the mulch in place and preventing undesirable movement.

    Abstract: A weed guard which forms a barrier along the width and length of a fence line. The weed guard has a protective strip which is preferably flat. Each lateral edge of the protective strip has a plurality of anchoring segments, which resemble teeth, which extend downward and perpendicular to the protective strip. The protective strip has a plurality of perforations therein which form cut-outs which receive fence posts. In operation cut-outs are removed along the perforations and a fence post is received in the cutout. Next the anchoring segments are inserted into the ground. In this position, the protective strip prevents weeds from growing along the bottom edge of the fence line. In this way the aesthetic appearance of a fence line is improved.

  • Patent number: 8490326
    Abstract: A combination hydro straw mulch is used for hydroseeding and hydromulching for seed establishment and erosion control. The formulation of the mulch is preferably, but not limited to, approximately 85% hammermilled straw, approximately 10% hammermilled paper, and approximately 5% processed jute fibers. The hammermilled straw is preferably Kentucky Bluegrass straw. The hammermilled paper particles are used for its water holding capacity. The paper aids in pumpability and reduces the amount of water required for pumping a quantity of mulch. The processed jute fibers tangle the straw fibers on the ground to produce a secure ground covering. The hydro straw mulch of the present invention may include other additives as well. Tackifiers and flocculants aid pumpability and help tack the straw fibers to the ground and aid in water infiltration and water clarity. A surfactant ensures wettability. Other additives include green dye.

    Abstract: An over wintering method for storing mature root crops in soil in the ground in a geographic area with a seasonal climate, where the winter months are consistently below zero degrees Celsius overnight, including the steps: (a) during the fall months, positioning an impermeable material above a row of mature root crop; (b) distributing an insulating material above the impermeable material sufficient to provide an insulating layer of at least 30 centimeters in depth across the row; (c) up to six months following step (b), removing the impermeable material and the insulating material, and harvesting the root crop.

  • Patent number: 8039106
    Abstract: A novel class of flowable biomass feedstock particles with unusually large surface areas that can be manufactured in remarkably uniform sizes using low-energy comminution techniques. The feedstock particles are roughly parallelepiped in shape and characterized by a length dimension (L) aligned substantially with the grain direction and defining a substantially uniform distance along the grain, a width dimension (W) normal to L and aligned cross grain, and a height dimension (H) normal to W and L. The particles exhibit a disrupted grain structure with prominent end and surface checks that greatly enhances their skeletal surface area as compared to their envelope surface area. The L×H dimensions define a pair of substantially parallel side surfaces characterized by substantially intact longitudinally arrayed fibers. The W×H dimensions define a pair of substantially parallel end surfaces characterized by crosscut fibers and end checking between fibers.

  • Patent number: 8007884
    Abstract: The invention provides processes for coating the surface of substrates such as a sheet, film, foam, fiber, etc., with a curable liquid resin or solution of curable resin, then in one embodiment, stably attaching a superabsorbent polymeric powder to such resin, and then curing the resin to form a coated superabsorbent product. Such substrates may include polymeric materials. Other process embodiments utilizing curable and thermoplastic resinous powders may be used instead of curable liquid resins and resulting products are included in the invention. The coated product may be utilized for water and nutrient retention in combination with irrigation, erosion control, to direct plant root growth, and to clean up standing water and petroleum spills.

  • Publication number: 20110203170
    Abstract: A process and system for producing sterilized shredded material such as mulch or compost introduces a sterilant during a grinder stage for forming the shredded material, wherein the sterilant is presented by introduction with water via a spray bar at the grinder stage. The grinder stage may have a preliminary first (initial) grinder stage. The process may include shearing wood parts to a uniform size prior to the first grinder stage. The resulting shredded material can be irradiated or subjected to external heat. Testing of the resulting output shredded material can be conducted to determine the presence of mold spores, or the like and, if found, for redirecting the shredded material to the grinder stage associated with the sterilant.

  • Patent number: 7966765
    Abstract: In one aspect there is provided a blended mulch product which can be mixed with water and spray-applied to a ground surface to form an erosion control medium, the blended mulch product comprising: about 75% to about 92% by weight ligno-cellulosic fibers; about 1% to about 10% by weight substantially straight synthetic fibers; and a tackifier; wherein the substantially straight synthetic fibers maintain their substantially straight form in the blended mulch product and the erosion control medium. Also provided are slurries in which the blended mulch product is mixed with water to produce the slurry, the slurry is spray-applied to a ground surface and the slurry dries on the ground surface to form an erosion control medium.

  • Patent number: 7900394
    Abstract: A method for making a hydraulically applied mulch using a natural biofiber material preferably comprising of 100% cotton byproduct or a mixture of cotton byproducts and other biomaterials selected such as, hay, grass, kenaf, straw, coconut, bamboo, hemp, bagasse and plant residue (cereal grains, rice, soybeans, grass seed, wood, sawdust, wood pulp, paper, or mixtures thereof). These fibers bear a natural waxy coating. The method includes the optional step of introducing the shredded biofiber composition into a first steaming chamber to stem the biofiber composition, followed by shredding the biofiber composition, and then introducing the shredded biofiber composition into a second steaming chamber to steam, break down and create porosity in the waxy coating of the fibers causing the fibers to become more hydrophilic. The biofibers are steamed followed by drying causing them to curl or physically deform.
