As the world of biochar expands, the need for definitive research to answer core questions grows. One such question is “What is the role of adsorption and when does it make a pivotal difference in growing situations?” Answering those questions has been hampered by the historical absence of adsorption as a monitored property in soils and soil components (as compared to CEC) and the lack of a reliable method to create low and high adsorption biochars. While there is little that can be done about the former situation, the later may have a fairly facile solution, which will be presented here.
