In this study, the amounts of phosphorus (P) in nine types of biochar (one natural woody biochar and eight manufactured plant derived biochars) extractable by deionized water, 0.5N NaHCO3 (pH=8.5) and 0.5N H2SO4, respectively, and P adsorption on single biochar or soil/biochar mixtures were examined...
