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.

    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.

  • Patent number: 8481160
    Abstract: An industrial feedstock of plant biomass particles having fibers aligned in a grain, wherein the particles are individually characterized by a length dimension (L) aligned substantially parallel to the grain, a width dimension (W) normal to L and aligned cross grain, and a height dimension (H) normal to W and L, wherein 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, and the L×W dimensions define a pair of substantially parallel top and bottom surfaces, and wherein the particles in the feedstock are collectively characterized by having a bimodal or multimodal size distribution.

  • Patent number: 8361542
    Abstract: Methods for applying a treatment, such as colorant, to an installed landscaping material (such as wood chips or mulch), reducing the need to replace worn or weathered material. The methods include applying a pre-treatment to protect elements proximate the landscape material that are not to be treated, applying a treatment liquid to the landscaping material by spraying, and then rinsing any elements proximate the landscape material that may have be inadvertently and undesirably treated. Also described is a sprayer apparatus for applying treatment liquid to a landscaping material. The sprayer apparatus includes first and second spray outlets and an agitator therebetween. In use, the landscape material to be treated is first sprayed, the material is agitated (e.g., turned), and a second spray of treatment liquid is applied to the landscape material.

  • Patent number: 8322070
    Abstract: The present invention provides a method for producing a mulching sheet which easy to biodegrade and can be produced at a low cost. A cotton waste sheet is prepared with randomly accumulated cotton waste and impurities selected from a group consisting of cottonseeds, stems, leaves and calyxes of cotton tree. Water is sprayed to the cotton waste sheet. Thereafter, the cotton waste sheet is passed between a pair of calender rolls each taking a form of a Japanese drum, while being heated, to press the cotton waste sheet in the thickness direction. The cotton waste is thereby closed, and the obtained mulching sheet has a high tensile strength. Furthermore, the impurities in the cotton waste sheet are crushed or flatted. The mulching sheet is a mixture of parts made of flatted impurities and parts made of cotton waste.
