Abstract

The disclosure provides a method of composting cattle waste comprising the steps of forming a windrow of beef cattle manure, adding moisture to the windrow, monitoring the temperature of the windrow, maintaining the moisture content of the windrow and mixing the windrow after a predetermined temperature drop. The windrow is formed in an outdoor environment, preferably without a carbon amendment. During active composting, the moisture content of the organic portion of the windrow is kept within a range of 40% to 65% by weight. Steps of monitoring the temperature, addition moisture, and mixing are repeated until such steps do not create a predetermined significant temperature increase following the step of mixing. The manure is cured and analyzed as final steps in the process before packaging and shipping.

Claims

1. A method of composting animal waste comprising the steps of:

(a) forming a pile of waste in an outdoor environment;

(b) monitoring the temperature of the pile;

(c) monitoring the moisture content of the pile;

(d) mixing the pile after a predetermined temperature drop;

(e) adding moisture to the pile to maintain the moisture content of the pile within a predetermined moisture range; and

(f) repeating the steps of monitoring the temperature and moisture, adding moisture, and mixing until such steps do not create a significant temperature increase following the step of mixing.

2. The method of claim 1, further comprising the step of bringing the pile to a predetermined moisture level and mixing the pile after the step of forming the pile and before the step of monitoring the temperature of the pile.

3. The method of claim 2, further comprising the step of curing and mixing the pile after prior steps do not create a significant temperature increase.

4. The method of claim 3, further comprising the step of analyzing samples of the pile to determine pile nutrient, moisture, and weed seed content.

5. The method of claim 2, wherein the pile includes organic matter and wherein the step of bringing the pile to predetermined moisture level comprises bringing the moisture content of the organic material portion of the pile within the range of 40 tog 65 percent moisture, on a weight basis.

6. The method of claim 1, further comprising the steps of curing and mixing the pile after prior steps do not create a significant temperature increase.

7. The method of claim 1, wherein the waste includes beef cattle manure.

8. The method of claim 7, wherein the waste includes beef cattle carcasses.

9. The method of claim 1, wherein the pile is formed into at least one windrow.

10. The method of claim 9, wherein the initial height and width of the windrow is at least three feet high and eight feet wide.

11. The method of claim 10, wherein the step of mixing is accomplished with a mixer.

12. The method of claim 1, wherein a significant carbon amendment is not added to the pile.

13. The method of claim 1, wherein added moisture is obtained at least partially from pile effluent.

14. The method of claim 1, wherein the temperature is monitored at least every other day.

15. The method of claim 14, further comprising the step of monitoring the oxygen level.

16. The method of claim 1, wherein the step of adding moisture to the pile includes bringing the moisture content of the pile within a range from 40 to 65 percent on a weight basis.

17. A soil enhancement produced by a process including:

(a) collecting cattle waste;

(b) forming the cattle waste into at least one pile;

(c) bringing the moisture level of the pile within a predetermined range;

(d) monitoring the temperature of the pile;

(e) mixing the pile upon a predetermined temperature drop of the pile; and

(f) repeating the steps of monitoring and mixing until mixing results in no significant temperature increase.

18. The soil enhancement of claim 17, wherein the process further includes the step of checking the moisture content of the pile after a predetermined temperature drop and adding moisture to the pile as needed to bring the moisture content within a predetermined range.

19. The soil enhancement of claim 18, wherein the cattle waste includes organic matter and wherein the predetermined range of moisture content is between 40 and 65 percent of the organic matter portion of the waste.

20. The soil enhancement of claim 18, wherein the process further comprises the step of curing the waste after mixing results in no significant temperature increase.

21. The soil enhancement of claim 18, wherein the pile is formed into an outdoor windrow.

22. The soil enhancement of claim 18, wherein a significant carbon amendment is not added to the pile.

23. A method of composting cattle waste comprising the steps of:

(a) forming a windrow of beef cattle manure including organic matter in an outdoor environment;

(b) bringing the moisture content of the organic matter in the windrow within a range of 40 to 65 percent;

(c) monitoring the temperature of the windrow;

(d) adding moisture as needed to bring the moisture content of the organic matter in the windrow to within the range of 40 to 65 percent and mixing the windrow after a predetermined temperature drop;

(e) repeating the steps of monitoring the temperature, adding moisture, and mixing until such steps do not create a predetermined significant temperature increase following the step of mixing; and

(f) curing the manure.
