Biochar Offsets
Submitted by PSmall on Sun, 08/22/2010 - 17:16I have been producing small quantities of biochar at home and using it in my compost.

Opinion: Spreading biosolids still the best option
Submitted by PSmall on Fri, 03/05/2010 - 16:13A concise evaluation of the problems and the practical options involving biosolids.
