improving soil properties by using charcoal residues, including organic carbon and ashes. High content
of the base ions in the ashes could lead to increase the pH and strongly affect the study results. The
results would also mask the potential effects of the forms of organic C in the charcoal. In this study, we
reduced the influence of ashes by using water-washed charcoal and studied its effects on soil chemical
properties after incubations under abiotic and biotic conditions.
