Abstract

A method for applying PAM to soil wherein said PAM is intermixed, impregnated and/or applied to solid carriers.

Claims (59)

1. A method for applying polyacrylamide (PAM) to soil comprising;

impregnating and/or applying water-soluble PAM to a solid carrier;

leaching said PAM out of said solid carrier with water into said soil;

binding said PAM to said soil;

wherein application rates of said solid carrier to said soil is related to desired amount of said PAM to be metered to said soil.

2. The method of claim 1 wherein said solid carrier is applied to soil through conventional means, such as, spreaders.

3. The method of claim 1 wherein said water is from rain.

4. The method of claim 1 wherein said PAM acts as a flocculating agent and/or as a settling agent.

5. The method of claim 1 wherein said PAM is in a dry granular form and/or emulsified state.

6. The method of claim 1 further comprising:

adding fertilizers and/or soil amendments to said solid carrier.

7. The method of claim 1 wherein said solid carrier comprises fibrous material, a seed, a mulch, and/or a material that was previously treated with PAM;

wherein said material includes material from mineral and coal processing, petroleum production, paper making, water treating, and food processing.

8. The method of claim 1 wherein said solid carrier is comprised of nitrogen, phosphorus and/or potassium.

9. The method of claim 1 further comprising:

adding pesticides or herbicides to said solid carrier.

10. The method of claim 1 wherein said solid carrier is an erosion control BMP such as seed and mulch or erosion mat.

11. The method of claim 1 wherein said PAM is anionic.

12. The method of claim 1 wherein said PAM reduces runoff and leaching of microbes in said soil, reduces soil-borne diseases within said soil and/or reduces runoff of pesticides, herbicides and/or fertilizers.

13. The method of claim 1 wherein said solid carrier is in the form of a granule, extruded pellet, woven mat, flake and/or formed bale.

14. The method of claim 1 wherein said PAM improves water infiltration of said soil, thereby improving soils ability to absorb water;

improves water infiltration of said soil, thereby reducing amount and/or frequency of water needed for said soil;

acts as an anticrusting agent in said soil; and/or

controls erosive forces by holding soils in place and ionically bonding them together to increase particle size.

15. The method of claim 1 wherein said solid carrier comprises a fertilizer.

16. The method of claim 1 wherein said solid carrier further comprises disease causing microbes, such as animal manure.

17. The method of claim 1 wherein said solid carrier further comprises aluminum sulfate and/or calcium oxide.

18. A method of applying polyacrylamide (PAM) to soil comprising:

impregnating and/or applying water-soluble PAM to a solid carrier;

applying said solid carrier to soil;

applying water to said solid carrier;

leaching said PAM out of said solid carrier into said soil;

binding said PAM to said soil;

wherein application rates of said solid carrier to said soil is related to desired amount of said PAM to be metered to said soil.

19. The method of claim 1 wherein said solid carrier is comprised of a amendment, soil conditioner and/or waste product.

20. A method of applying polyacrylamide (PAM) to soil comprising:

impregnating and/or applying water-soluble PAM to a solid carrier;

applying said solid carrier to soil;

applying water to said solid carrier;

leaching said PAM out of said solid carrier into said soil;

binding said PAM to said soil;

wherein application rates of said solid carrier to said soil is related to desired amount of said PAM to be metered to said soil;

wherein said solid carrier is an agglomerate.

21. The method of claim 1 wherein said solid carrier is made by a size reduction and/or an agglomeration process, including agitation, pressure, liquid and/or thermal;

wherein said agitation process includes the methods of;

tumbling, mixing, granulation, pelletizing, balling, conditioning, and/or instantizing;

wherein said pressure process includes the methods of briquetting, compacting, extrusion, pelleting, molding, tabletting and/or isostatic pressing;

wherein said liquid process includes the methods of spray drying, spray granulation, fluid bed granulation, prilling, agglomeration in liquid media, oil agglomeration and/or globulation;

wherein said thermal process includes the methods of sintering, induration, nodulizing, calcining, drying/solidification, partial gasification/charring and flaking.

22. A delivery system used to apply polyacrylamide (PAM) to soil comprising a solid carrier and water-soluble PAM;

wherein said solid carrier is made by an agglomeration process, including agitation, pressure, liquid and thermal;

wherein application rates of said solid carrier to said soil is related to desired amount of said PAM to be metered to said soil;

wherein said water-soluble PAM binds to said soil.

23. A method of applying polyacrylamide (PAM) to soil comprising:

impregnating and/or applying water-soluble PAM to a solid carrier;

leaching said PAM out of said solid carrier with water into said soil;

binding said PAM to said soil;

wherein said solid carrier comprises a fibrous material;

wherein application rates of said solid carrier to said soil is related to desired amount of said PAM to be metered to said soil.
