Abstract:From a glass-tube experiment on air-dried soil column the following results were observed: (1) The CaCl2 solution moved upward from the "round water table" to a height of 108.5 cm in 136 days, (2) within the supported capillary water zone, the water front moved rapidly and the rate of water flow was great, but in the soil above that zone the movement of water front was slowed down and the rate of water flow decreased, (3) all kinds of soil water in liquid-phase (including film water) moved with salts, which caused the rate of soil water flow and soil evaporation to decrease.
