Characterization Of phosphoric acid biochar derived from rubber wood sawdust for enhancement Of urea fertilizer impregnation

This paper examines the physiochemical properties of phosphoric acid treated biochar for improvement of urea fertilizer impregnation process. The biochar was heated with phosphoric acid (H3PO4) of 1.5 M (TB1) and 1 M (TB2) concentrations at 80 and 90°C temperature respectively. The treated biochar t...
