Abstract

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.

Claims (24)

1. A fibrous hydro mulch product comprising:

hammermilled straw having separated fibers partially released from the straw, finely divided paper particles mixed with the hammermilled straw, jute fibers mixed with the hammermilled straw and the finely divided paper particles.

2. The product of claim 1 , further comprising an adhesive tackifier, mixed with the hammermilled straw, the finely divided paper particles and the jute fibers.

3. The product of claim 2 , further comprising a surfactant mixed with the hammermilled straw, the finely divided paper particles and the jute fibers.

4. The product of claim 1 , further comprising a surfactant mixed with the hammermilled straw, the finely divided paper particles and the jute fibers.

5. The product of claim 1 , wherein the mixed hammermilled straw, finely divided paper particles and jute fibers are mixed with a tackifier, a flocculent, dye and a surfactant for forming a hydro mulch product.

6. The hydro mulch product of claim 5 , wherein the tackifier, flocculant, and surfactant are also agro chemicals that aid growth.

7. The product of claim 1 , wherein the hammermilled straw is selected from the group consisting of straw from grass seed, cereal grains, rice, soybeans, kenaf, and combinations thereof.

8. The product of claim 1 , wherein the hammermilled straw is present at about 60 to about 90 percent, the finely divided paper particles are present at about 5 to about 20 percent, and the jute fibers are present at about 2 to about 10 percent, all by weight.

9. The product of claim 8 , further comprising about 0.025 to 5 percent tackifier and flocculent sufficient for tacking fiber together and to soil surface and to increase water infiltration and aid in water clarity, and less than 1 percent surfactant for wetting the hammermilled straw, the finely divided paper particles and the jute fibers upon the addition of water.

10. The product of claim 1 , wherein the jute fibers are used to tangle the straw fibers and paper particles.

11. The hydro mulch product of claim 1 , further comprising water in a ratio of about 100 gallons per 75 pounds of straw, paper fibers, and jute fibers, wherein the product can be applied by hydroseeder tower without clogging.

12. The hydro mulch product of claim 1 , wherein the straw is 6-13 mm in length and the jute fibers are 7-15 mm in length.

13. A fibrous hydro mulch product comprising:

hammermilled fine grass straw having separated fibers partially released from the straw, finely divided paper particles mixed with the hammermilled straw, jute fibers mixed with the hammermilled straw and the finely divided paper particles.

14. The product of claim 13 , wherein the fine grass straw is blue grass straw.

15. A fibrous hydro mulch product comprising:

hammermilled straw having separated fibers partially released from the straw, finely divided paper particles mixed with the hammermilled straw, jute fibers from burlap scrap mixed with the hammermilled straw and the finely divided paper particles.

16. A hydro mulch product made by the method of

hammermilling straw to provide providing fibrous straw with short straw shafts having fibers partially exposed from and extending from the straw shafts,

providing paper particles,

providing jute fibers,

mixing the fibrous straw, the paper particles and the jute fibers, and

packaging the compressed mixed fibrous straw, paper particles and jute fibers for transportation to a point of use.
