What is the significance of the shape and size of a windrow?
To generate the heat necessary for speeding the decomposition process and degrading undesirable elements, the windrow should be four to six feet deep. If the windrow is too flat or spread out, required temperatures cannot be achieved. The inverted “V” of the ACS process creates the desired chimney effect. If the row is too high (above 6 feet), anaerobic conditions can easily set in.
