B. A soil column is connected to a hanging water column apparatus and allowed to reach equilibrium (qw = 0) - see figure below. The soil surface is loosely covered with plastic so there is no evaporation. Calculate the matric potential and effective radius of water-filled pores at the top of the soil sample. hm = ? 10 cm niter membrane with abubblin pressure of -100 cm H,0 20 cm
