摘要:
Superabsorbent polymer (SAP) products for use in agricultural applications, and methods of making and using the same are disclosed. Certain of the SAPs include a monomer or a mixture of monomers, selected from acrylic acid, acrylamide, acrylonitrile, methacrylamide, 2-acryloamido-2-methyl-propanesulfonic acid, methacrylic acid, vinyl sulfonic acid, ethyl acrylate, potassium acrylate, derivatives thereof or mixtures thereof, that is graft polymerized onto a starch in the presence of an initiator to form a starch graft copolymer.

A method for coloring sea shells for use as mulch comprises receiving a quantity of shells; washing the shells to remove debris therefrom; segregating the shells to separate relatively larger shells for further processing; at least partially drying the shells; applying a coloring agent to the shells; and drying the colored shells.

A combination hydro straw mulch is used for hydroseeding and hydromulching for seed establishment and erosion control. The formulation of 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 wetability. Other additives include green dye.

Disclosed are soil additives capable of hydrophilizing soil particles and/or increase available water capacity in soil. The soil additive are capable of increasing the available water content/capacity (AWC) in soils, the additive in one embodiment comprising a polymer composition having a hydrophilic portion and a hydrophobic portion, wherein the hydrophobic portion of the copolymer binds with the soil particle surface and the hydrophilic portion of the copolymer can bind with water. This results in the prevention, arrest or decelerated loss of water from the targeted area, for example the plant root zone, which allows for improved water usage efficiency by plants, grasses, vegetation, etc.
摘要:
A coating is provided for a landscaping material, comprising a hybrid network of high functionality structured oligomeric siloxane and a polyalkylene glycol coupled with a co-product of monopropylene glycol and propylene oxide. The coating may be coupled with a pigmented colorant and be further mixed with a water-based carrier. The coating is contemplated to increase the efficiency of the mulch as compared to plain mulch material and other coating materials. A testing apparatus, including a retention basin and water measuring basin, are also defined as a means to determine the efficiency of the mulch material and its corresponding coating.

The present method is an improved method of applying particulate groundcover around plants. This method involves the steps of providing a plurality of substantially planar flexible sheet-members each including an outer surface and an opposite inner surface and first and second opposed edges, die inner surface having a first-edge-adjacent portion with a first surface-fastener patch thereon, the outer surface having a second surface-fastener patch thereon extending from near the second edge toward the first edge; wrapping each sheet-member about the leafy portion of a plant into a substantially cylindrical shape and temporarily securing together the first and second patches thereof to expose the base of the plant stem and surrounding ground; applying groundcover around and between the plants including to the bases of the stems thereof; and decoupling the first and second patches of each sheet-member and removing the sheet-members to allow the leafy portions of the plant to spread over the groundcover.

The present invention relates to concrete mulch and methods for making the same. The concrete mulch is made from crushed waste concrete, a colorant and a binder which colors the concrete pieces to look like natural mulch. The concrete mulch is available in a wide variety of shapes and sizes; however, it is preferred for the concrete mulch to look like natural rock, bark nuggets or natural mulch.

This invention allows for the even distribution of mulch with minimal human effort. Mulch distribution is common with today's homeowner and business owner and will provide a certain aesthetic appeal to the vegetation of a flower bed or the curb appeal of a building. The primary difficulty with mulch distribution is getting the mulch to the site. This device will consist of a dolly, which will enable the user to load a desired quantity of mulch from a central loading site and then transport the mulch easily to the desired area and allow the individual to distribute the mulch evenly. This device can be filled remotely with a mulch truck so that the individual homeowner or business owner does not have to physically lift great amounts of mulch over long periods of time in order to put them on flower beds or around other areas of vegetation.
