Compost Preparation/87
oxygen is used by microorganisms, heat is set free and the air temperature rises. The warm air current created rises to the top of the pile. This is called the chimney effect. The factors that affect the
rate of internal air flow are pile size and structure, moisture content and the differential between ambient air and internal pile temperatures.

Turning
A well built compost pile runs out of oxygen in 48 to 96 hours and then enters an anaerobic
state. To prevent this, the pile should be disassembled and then reassembled. The purposes of this
turning procedure are:

1. To aerate the pile, preventing anaerobic composting.

2. To add water lost through evaporation.

3. To mix in supplements as required.
4. To fully mix the compost, preventing uneven decomposition.
As a consequence of microbial decomposition, the compost pi'e begins to shrink and becomes
more compact. Coupled with loose water gravitating downward and water generated by microbes in
the inner active areas, this compaction closes the air spaces and stifles aerobic action, particularly in
the core at the bottom center. Through the use of a long stemmed thermometer reaching to the
center of the pile, the time of oxygen depletion can be monitored by watching temperature. When
the temperature begins to drop, indicating a slowing of microbial action, it is time to turn the compost.
