When soil water potential in a sandy loam soil goes from -0.1 to -10 bars, the height of an equivalent column of capillary water increases 100 times. The rate of water movement (the hydraulic conductivity): O increases by a factor of about 100 times increases by a factor of about 10 times remains little affected O decreases by a factor of about 1000 times decreases by a factor of about 10 times
