Fig. 1. Cross-sectional view (A): Chamber pairs situated at the three different elevations, labeled A, B, or C, in the biodrying compost pile. The initial depth of the pile was approximately 1.2 m. Top view of compost pile (B): Circles represent a set of three chamber pairs situated vertically through the pile. Twenty sets of three pairs were situated along horizontal distances on either side of the pile. The four thermocouples located at the horizontal distance of 9.5 m (equivalent with sample set #19) had initial elevations of 94, 74, 45, and 16 cm.
