To calculate the downward passage of water through the soil, the loss of salt from a column of soil was divided by salt concentration of the solution leaving the bottom of the column. This concentration was assumed equal to the mean concentration of the lowest part of the column during leaching. Conditions limiting this method were discussed.
Capillary rise was calculated in a similar way. Rainfall, soil moisture and capillary rise were considered in calculation of evapotranspiration.
