UBET members, together with Wilson Biochar Associates and the USDA Agricultural Research Service at OSU, conducted a pot trial last spring that compared two kinds of high carbon boiler ash with biochar and lime. We presented the results as a poster at the US Biochar Initiative Symposium in Corvallis last August. The poster is too big to print out and share, so we recently compiled the information into a document that is easier to read. You can download the pdf file here: https://www.dropbox.com/s/6o0wtd1ip1st1vn/biochar_pasture_soil_pot_trial%20paper.pdf?dl=0
