I live in an arid area with strong winds and very hot summers. I've tried a regular compost pile but have had problems with pests (migratory rats that seem to be attracted by the smell) and the heat: it dries the pile up faster than we can add new organic material to it.
I came across the idea of having an underground compost. For this purpose, I bought this small receptacle:
My idea was to dig a hole and put it in the ground and fill it daily with organic material. I'd put drill holes in it so the excess liquid can drain. Because our soil is very loamy, I'd surround it with a layer of sand to support drainage.
What I'm hoping for is a composting system that doesn't attract any pests, and doesn't get dried out as fast as a regular overground compost. When it's done, I'd just shovel out the soil and fill it anew.
Does this make sense?
Are there any weaknesses I'm overlooking?
What size should I drill the drainage holes, and how many?
