Physicochemical changes in pyrogenic organic matter ( biochar ) after 15 months of field aging

  author={Abira Mukherjee and Andrew R Zimmerman and Rasha Hamdan and William T. Cooper},
Predicting the effects of pyrogenic organic matter (OM) addition (either natural or intentional as in the case of biochar amendment) on soil chemistry and crop yields has been hampered by a lack of understanding of how pyrogenic OM evolves in the environment over time. This work compared the physicochemical characteristics of newly made and 15-month-field-aged biochars and biochar–soil mixtures. After aging, biochars made by pyrolysis of wood and grass at 250, 400 and 650 C exhibited 5-fold… CONTINUE READING
