Abstract

A method for suppressing the formation of ammonia comprising providing a carrier material to a container having a headspace; providing a bacteria, an acidifier and an odor inhibitor to the carrier material, the bacteria comprising Staphylococcus - xylosus or Staphylococcus - cohnii bacteria, and the odor inhibitor comprising a salt of an aminopolycarboxylic acid compound; and applying animal waste to the carrier material; wherein there is a 5 to 98 percent improvement of ammonia content in the headspace as compared to an untreated control comprising a container containing the carrier material and the bacteria and not contain the odor inhibitor.

Claims (13)

1. A method for suppressing the formation of ammonia comprising:

providing a carrier material to a container having a headspace;

providing an acidifier and an odor inhibitor to the carrier material, the odor inhibitor comprising a sodium or potassium salt of an aminopolycarboxylic acid compound; and

applying animal waste to the carrier material; wherein the animal waste comprises Staphylococcus - xylosus or Staphylococcus - cohnii bacteria, and wherein there is a 5 to 98 percent improvement of ammonia content in the headspace as compared to an untreated control comprising a container containing the carrier material and the bacteria and not contain the odor inhibitor.

2. The method of claim 1 , the method further comprising: providing an additive material to the carrier material, wherein the additive material comprises diatomite, citrate salts, talc, gypsum, calcium carbonate, sand, glass, dirt, alumina, alumina-silicates, silicates, or a combination thereof.

3. The method of claim 1 , wherein the odor inhibitor is a salt of an aminopolycarboxylic acid compound having an ethylenediamine or diethylenetriamine backbone.

4. The method claim 1 , wherein the odor inhibitor is a salt of ethylenediaminetetraacetic acid, a salt of diethylenetriaminepentaacetic acid, a salt of N-hydroxyethylethylenediaminetriacetic acid, or a mixture of two or more thereof.

5. The method of claim 1 , wherein the carrier material is non-porous.

6. The method of claim 1 , wherein the animal waste contains urea or uric acid.

7. The method of claim 1 , wherein the odor inhibitor comprises 1.0 to 5.0 weight percent of the combination of the acidifier, the odor inhibitor and the carrier material.

8. The method of claim 1 , wherein the acidifier comprises 0.5 to 4.0 weight percent of the combination of the acidifier, the odor inhibitor and the carrier material.

9. The method of claim 1 wherein the carrier is wood shavings, hay, straw, ground straw, wood chips, saw dust, pelletized saw dust, paper, chopped corn cobs, peanut hulls, cocoa hulls, rice hulls, wheat grass, grass, flax, oat, wheat, rye, shredded paper, walnut husks, coconut husks, sand or mixtures thereof.

10. The method of claim 1 , wherein the acidifier is sodium bisulfate, hydrated potassium aluminum sulfate, sulfuric acid, ferrous sulfate, or phosphoric acid.
