Abstract: This invention relates to the art of fertilizers and, more particularly, to a coated granular fertilizer in which the dissolution rates of water-soluble fertilizer components are controlled by coating or encapsulating a granular fertilizer. The coating for the timed-release fertilizer is derived from plant cellulose extracted from hemp cellulose, sugar cane cellulose, or other plant-based cellulose.

Abstract: An artificial turf field system is provided. The system may include a plurality of synthetic turf strands attached to a backing layer and an infill material positioned between the synthetic turf stands. The infill material may include a plurality of porous particles. A sub-layer may be included beneath the backing layer, and may be formed of a resilient material.

Abstract: Natural fiber mulch mats are prepared from natural fibers, bicomponent fibers, and optionally other synthetic fibers, and consolidated at a temperature sufficient to melt a lower melting polymer of the polymers used to prepare the bicomponent fiber. The mulch mat may be prepared without conventional binders and without a polymer netting, yet exhibits good handling properties and superior water holding properties as compared to melting-containing products, without the drawbacks of the latter.

Abstract: A hydraulically-applied mulch matrix comprising non-porous particles, porous particles and mixtures thereof combined with a mechanically and or chemically bonded fiber mulch mixed within a high viscosity slurry to keep the particles in suspension for dispersion onto soil surfaces with mulch spraying equipment for enhanced erosion control and higher level plant establishment.

Abstract: According to one aspect of the present invention, there is provided a visual attenuation composition applicable to a landscape to visually attenuate or camouflage the landscape to approximate color characteristics of the surrounding terrain. The visual attenuation composition includes a colorant selected from the group consisting of a pigment, a dye, and combinations thereof, and optionally includes an additive selected from the group consisting of a flocculent, a tackifier, a stabilizer, and combinations thereof. The visual attenuation composition may further include a liquid medium such as water to form a slurry suitable for spray application. The visual attenuation composition described herein can be combined with a soil treatment product to impart desirable color and colorfastness. Alternatively, the soil treatment product can be first applied to the landscape prior to the application of the visual attenuation composition.

Abstract: According to one aspect of the present invention, a soil treatment composition is provided. In one embodiment, the soil treatment composition includes an acidic material containing at least one organic acid and at least one inorganic acid, and a plurality of substrate particles supporting the acidic material. In another embodiment, the substrate particles are sized to be retained on a 100 mesh sieve. In yet another embodiment, the organic acid includes an oxalic acid, a citric acid, or combinations thereof. In yet another embodiment, the soil treatment composition further includes a soil/plant nutrient material.

Abstract: Flaked mulch products having a density similar to that of seed which is to be established, comprise an agglomerated and compacted natural raw material whose density is adjusted to within 50% of the seed.

Abstract: Mulch flakes made from finely divided paper and/or wood, and a surfactant. The flakes include surfactant which allows them to very quickly absorb about nine times their weight in water. This quick absorbency feature allows the flakes to be added more quickly to jet-agitated hydro-mulching tanks. Once sprayed on the ground, the flakes substantially reduce water run-off and soil erosion as compared to other mulches.

Abstract: Porous calcined clay sports field conditioners exhibit excellent playability while also displaying excellent drainage, freedom from compaction, and moisture retention under hot, dry conditions. The conditioners are non-hydrating granulates of narrow particle size distribution and are preferably of a red to brown coloration.
