Easy access for turning with a three sided pallet bin
Aeration is necessary to provide the composting microbes and larger creatures with the oxygen necessary to convert the organic matter into compost and to achieve the temperatures necessary for the
more rapid decomposition of hot aerobic composting.
If the material is not turned composting will still happen but will take longer, a year or 18 months in some cases, and may become anaerobic. Aeration
by turning the composting material will involve extra work but I believe it is worth it.
The main reason for turning the material is that it introduces more oxygen into which increases the speed of decomposition by the aerobic
composting bacteria. quickly break down a compost pile. This is results in the heap a heating up.
An additional benefit is that the process of turning the heap will break up any matted material
which may have started to decompose anaerobically producing greenhouse gases and decomposing more slowly. Turning also in opening the material increases surface area of the organic matter resulting in faster decomposition. A further benefit is that it
enables the moisture content of the pile to be checked and adjusted.
If using pallet or New Zealand bins without a front, or where the front panels can be easily removed, the material to be turned from one bin to the next
using a garden fork. However, there are other techniques and bins which avoid the need to turn the contents and as some of these are applicable to the entry level Dalek bin, I will start with them.
