FIG. 5.

Daily average ambient, soil (5-cm depth), and compost temperatures for the control (A) and AS700 (B) treatments; soil temperatures were used to estimate manure temperatures in feedlot pens. Triangles on the x axis indicate sample times. Compost temperatures (i.e., top and center) represent the mean of two replicates, and vertical bars indicate the standard error of the mean. Box 1 indicates the time at which cattle were removed from the feedlot (17 July 2005), box 2 indicates the time at which compost windrows were established (4 October 2005), box 3 indicates the end of the active composting period and the commencement of the curing compost phase, and box 4 indicates the termination of the composting period. Triangles located on the x axis indicate compost turning times. The arrow indicates a period of variable temperature between the replicate compost piles for AS700 compost.
