Abstract

Some results of 28 years' measurements of moisture conservation and use in soil tanks and field plots are described. Most of the rainfall received in south-western Saskatchewan is soon returned to the atmosphere by evaporation from bare soil or by transpiration from crops. Only 21% of the precipitation is conserved in summerfallow during the 21-month summerfallow period. Wheat yield is determined largely by the moisture stored in the soil at seeding time and by the subsequent rainfall. Rough estimates of evaporation from soil can be made under semi-arid conditions, such as in southwestern Saskatchewan, on the basis of predetermined evaporation curves giving the loss for different soil moisture conditions. Detailed data on capillary conductivity and diffusion coefficients are needed for computing moisture movement through soil to an evaporating surface.-Author's summary.
