This week’s guest is ecologist and author Julian Doberski. If you think about compost heaps, how much do you really think about the living micro and macro organisms that dwell within them, how they contribute to the composting process and how what you do to your heap can increase or decrease their chances of survival?

Julian has written about the science of what goes on in a compost heap and about the living organisms who provide the ‘hard graft’ of transforming waste organic matter in his latest publication The Science of Compost. I spoke to Julian to find out more.

What We Talk About

What is compost?

Does what go in also come out? Eg if we want a high nitrogen compost product should we use raw materials that are also high in nitrogen?

How do you know what you’ll be getting as an end product?

How do you get the right balance of the organisms that break down the heap?

The correct ratio of woody versus green materials in a compost heap

What makes a compost heap break down, apart from the organisms in it?
