Fresh manure collected from cattle feedlots, sheep and goat houses were composted in windrow piles. The pile temperatures peaked between 2-32 days; thermophilic temperatures were 66.2 to 78.7 degrees C. Pile temperatures were stable between 70-140 days depending on initial size of compost piles. The composition of nitrogen, phosphorus and potassium in finished composts were in the ranges of 2.6-2.9, 1.1-2.2, and 1.3-3.7 percent on dry matter basis respectively. The mass reduction after composting varied between 33.2 and 56.5 percent.
