This study aimed to systematically investigate the effects of low-temperature pyrolysis on the physicochemical properties and their internal connection. This work evaluated the influences of low-temperature pyrolysis on proximate analysis, element composition, stability, and structural features of prepared straw biochar from two feedstocks pyrolyzed at 225 °C to 600 °C. The different indicators, including yield, pH, fixed carbon (FC), volatile matter (VM), ash, C, H, O, N, P, K, Mg, Zn, and stability indexes, all followed exponential function...
