The effects of carbonization temperature on the pH and total K, Ca, and Mg of Artmisia ordosica biochar were investigated. The results showed that the concentrations of K, Ca, and Mg in the biochar increased with the increase of carbonization temperature. Compared with those at 300℃, the K, Ca, and Mg concentrations increased by 52.47%, 25.76%, and 86.32% at 900℃, respectively. The increase of element concentration is due to gradual removal of the volatile and decomposable components in Artmisia ordosica under different carbonization temperature.
