“…The total pore volume of the mixture increased with increase in biochar fractions, as indicated by the higher water content at saturation (Table ). The result is consistent with the results of previous studies (Abel et al, ; Blanco‐Canqui, ; Liu, Dugan, Masiello, & Gonnermann, ; Omondi et al, ; Ulyett, Sakrabani, Kibblewhite, & Hann, ). The increase in pore volume is mainly attributed to the increase in macroporosity caused by the dilution effect of adding larger diameter and low‐density biochar amendment to sand (Herath, Camps‐Arbestain, & Hedley, ; Lim et al, ).…”
