Do you add soil to your compost?
I was told to do this years ago but ignored the advice. Then I read Steve Solomon's writings on compost and he advises a layer of soil here and there within the compost pile. After thinking about it, it did make sense. Introducing the soil organisms into the pile makes sense since they cannot move there themselves, not at the rate they're able to travel.
I've always noted how much faster leaves decompose when laying on soil. So I started adding thin layers of soil into my compost bin. And I have to say it has made a difference in my usually warm (not hot) compost. My compost gets one turning and one year to mature before being used. Adding soil to the compost has definitely helped it mature faster, meaning that I end up with a finer, crumblier, more finished product.
