97 Biochar: Available Methods for Their Basic and Advanced Characterization

Oral Session
ASA Section: Environmental Quality
A cross-divisional session will bring together national and international experts who will present both basic and advanced spectroscopic methods to characterize biochars.  The goal is to discern the appropriate methods necessary to determine publishable biochar characterization results.
