Biochar particle size, shape, and porosity act together to

Based on these constraints, Eq 4 provides ψ < -16.5 kPa when d is less than 0.01 mm. This suggests that the pores smaller than 0.01 mm control water retention of our biochar-sand mixtures when ψ is less than -16.5 kPa. Given the small size of these pores, we assume this represents intrapores (pores inside biochar particles).
