Biochar particle size, shape, and porosity act together to influence soil water properties

Table 5

Median diameter of particles’ shortest chord (D_min50) and particles’ aspect ratio (A_R defined as D_min50 divided by D_max50) of biochar and sand used in this study.

We made measurements through dynamic image analysis (Camsizer, Retsch Technology, Germany).
