Webin biochar-amended soil, depending on the feedstock, with CMDB being more nutrient-rich than other forms of biochar. CEC benefits can also lead to the sequestration of heavy metals, effectively immobilizing or neutralizing them. The TR also indicates that most biochar has base pH which can be beneficial in acidic soils, with WebCorn stover biochar, switchgrass biochar, and lime (calcium carbonate) were applied at four rates (0, 52, 104, and 156 Mg ha −1) to acidic soil. Amendment type, application rate, and their interaction had significant effects ( p < 0.05) on soil pH, EC, and CEC of acidic soil. Exchangeable acidity was significantly affected by amendment type.
