Abstract
A tree or plant protection mat is provided, comprising: a top layer, having a first perimeter edge; a water-permeable bottom layer, having a second perimeter edge affixed either directly to the first perimeter edge, or indirectly to the first perimeter edge via an intervening sidewall; and a water-absorbing and releasing center layer disposed between the top and bottom layers, and comprising a section having superabsorbent particles and a section not having superabsorbent particles. Other mats and methods are provided.
Claims24
1-7. (canceled)
The mat of claim 28, wherein the top layer reduces or prevents evaporative water loss from the center layer.
The mat of claim 28, wherein the top layer is permeable to one or more of water, atmospheric water, dew, rainwater, applied water, or a combination of two or more thereof.
The mat of claim 28, wherein the top layer further comprises one or more perforations, funnel, hole, opening, channel, seam, or a combination of two or more thereof, to permit one or more of atmospheric water, dew, rainwater, applied water, or a combination of two or more thereof to penetrate into the center layer.
The mat of claim 28, wherein the top layer is flexible.
The mat of claim 28, wherein the top layer is flexible and is made of fabric, woven material, non-woven material, film, plastic, laminate, sheeting, polymer, or a combination of two or more thereof.
13-18. (canceled)
The mat of claim 28, wherein the superabsorbent particles comprise polyacrylic acid polymer, polyacrylate polymer, starch-grafted polymer, polyacrylamide, ethylene maleic anhydride polymer, carboxymethylcellulose, polyvinyl alcohol, polyethylene oxide, starch grafted copolymer of polyacrylonitrile, Group IA salt of polyacrylic acid, copolymer of two or more thereof, bio-based super absorbent polymer, starch-based super absorbent polymer, cellulose-based super absorbent polymer, biodegradable superabsorbent polymer, superabsorbent cellulosic hydrogel, or any combination thereof.
(canceled)
The mat of claim 28, wherein the first and second perimeter edges are affixed via sewing, heat-sealing, friction-welding, laser-welding, ultrasonic-welding, induction-welding, radio-frequency-welding, heat-bonding, adhesive, solvent-welding, stapling, or a combination of two or more thereof.
The mat of claim 28, wherein sections of soaker hose, drip emitters or micro-spray emitters are inserted in between of the top and bottom layers and the soaker hose and the emitters can be connected to an irrigation system via connections such as a hose connector.
