This should prove to be a valuable contribution to the accumulated knowledge on the benefits of combining biochar and compost (and incorporating references to our very own Clough et al on biochar and soil N dynamics) …

Hi Everyone,
A report that I worked on for the Washington Department of Ecology has now been published. Many thanks to Mark Fuchs at WDE for initiating this report on compost odor control, and for asking me to contribute a literature review of biochar use in compost and an appendix on the global history of biochar.
Here is a link to the study and the table of contents for the biochar sections. I hope this will be useful information for biochar producers and users.
