Biochar was prepared by the pyrolysis of sewage sludge at temperatures ranging between 300 and 700°C. Extraction and column leaching experiments were then conducted to investigate the amount of nitrogen (N), phosphorus (P), and potassium (K) as well as the water-soluble contents of the nutrients in...
