How do I get my compost to get hot over the winter?

Question

I know that with the right conditions, compost can get very hot at the centre of the pile, but I've never managed to achieve this. I live in southern Ontario, where the temperature rarely gets above zero between January and March, and regularly goes below -20, but I'd like to keep my compost 'composting' over the winter, rather than freezing. Is there any way to do it? Is it just getting the right mix of 'green' and 'brown' materials, or is there more to it than that?

Answer 1

The heat at the center of the pile is a function of bacterial decomposition activity.  As long as there is stuff to break down, the heat continues.  Air is also vital to supporting decomposition so regular turning to aerate is crucial as well as the proper moisture level.

Answer 2

you need to turn or airate the compost pile becuase the air is what causes it to begin to break down

Answer 3

I don't think anything except auxiliary heat or good insulation will help you.  The rate of heat generation is low, and 24/7 freezing temperatures will suck it away pretty fast.  If you do insulate, be sure enough air gets to it.
