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.

Claims (24)

1. A highly viscous hydraulically-applied mulch having a viscosity at low shear of about 300,000 cps or more, comprising:
a) at least one particulate component comprising porous inorganic particles, non-porous inorganic particles and mixtures thereof;
b) at least one fiber;
c) at least one suspending agent; and d) water.
2. The highly viscous hydraulically-applied mulch of claim 1 wherein the porous inorganic particle is a porous ceramic particle.
3. The highly viscous hydraulically-applied mulch of claim 1 wherein the porous inorganic particle is derived from smectite clay, perlite, vermiculite, zeolite, Fuller's earth, diatomatious earth, a clay and mixtures thereof.
4. The highly viscous hydraulically-applied mulch of claim 3, wherein at least one smectite clay is selected from the group consisting of bentonite, beidellite, nontronite, hectorite, saponite, attapulgite and sepiolite.
5. The highly viscous hydraulically-applied mulch of claim 3, wherein the smectite clay comprises montmorillinite.
6. The highly viscous hydraulically-applied mulch of claim 1, wherein the fibers comprise natural fibers and synthetic fibers.
7. The highly viscous hydraulically-applied mulch of claim 6, wherein at least one natural fiber is derived from wood, straw, cotton, flax, paper, coir, jute, compost, and mixtures thereof.
8. The highly viscous hydraulically-applied mulch of claim 6, wherein the synthetic fibers comprise polyester fiber, polypropylene fiber or mixtures thereof.
9. The highly viscous hydraulically-applied mulch of claim 6, wherein the fibers comprise mechanically bonded fibers, chemically bonded fibers or mixtures thereof.
10. The highly viscous hydraulically-applied mulch of claim 1, wherein the fibers comprise crimped fibers, non-crimped fiber, or mixtures thereof.
11. The highly viscous hydraulically-applied mulch of claim 1, wherein at least one suspending agent comprises a crosslinked hydrocolloid binder, a non-crosslinked hydrocolloid binder, or mixture thereof.
12. The highly viscous hydraulically-applied mulch of claim 11, wherein at least one hydrocolloid binder comprises agar, carrageenan, gelatin, pectin, or guar gum.
13. The highly viscous hydraulically-applied mulch of claim 11, wherein the suspending agent comprises a polyoxyethylene polyether, a polyacrylamide, a sodium polyacrylate, psyllium, chitosan, starch, bean mills or a mixture thereof.
14. The highly viscous hydraulically-applied mulch of claim 1, wherein the suspending agent is present in an amount of less than 15% by weight based on the total solids of the mulch.
15. The highly viscous hydraulically-applied mulch of claim 1, wherein the ratio of fibers to chemical binder is 7 to 30:1 by weight.
16. The highly viscous hydraulically-applied mulch of claim 1, further comprising as a soil amendment, fertilizer, compost, herbicide, pesticide, seed, stolon, live plant material or a mixture thereof.
17. The highly viscous mulch of claim 1, having a viscosity of about 500,000 cps or more.
18. The highly viscous mulch of claim 1, having a viscosity of about 1,000,000 cps or more.
19. The highly viscous mulch of claim. 1, comprising as a first component a mulch containing minimally 50 weight percent natural fibers, based on solids of the first component, and a second component comprising inorganic particles, the weight ratio of the first component to the second component being in the range of 1:10 to 10:1.
20. The highly viscous mulch of claim 1, comprising as a first component a mulch containing minimally 50 weight percent natural fibers, based on solids of the first component, and a second component comprising inorganic particles, the weight ratio of the first component to the second component being in the range of 1:3 to 3:1.
21. A method for stabilizing a soil surface, comprising applying a highly viscous hydraulically-applied mulch of claim 1 to the soil surface.
22. The method of claim 21, wherein preparation of a sprayable mulch matrix comprises mixing in a hydraulic seeding machine and applying to the soil surface.
23. The method of claim 22, wherein preparation of a sprayable mulch matrix comprises combining the fibers, the porous inorganic particles and the suspending agent are combined with water and the soil amendments within the hydraulic seeding machine.
24. The method of claim 12, further comprising applying a turf reinforcement mat to the soil along with said highly viscous hydraulically-applied mulch.
