To locate depth zones of evaporation, 30 cylinders containing 36 cm of Ida silt loam soil (initially wetted with 0.02 N CaCl 2 to maintain flocculation and furnish chloride ions) were subjected to various evaporation potentials for several different time intervals. Cumulative evaporation, water distribution, chloride distribution, and thickness of a dry surface layer, if one developed, were recorded. The evaporation zones lay between the 0‐ and 7‐cm depth, depending on the evaporation potential used, nominally 0.5, 0.75, 1.0, and 2.0 cm. 24 hr, and the duration, 1 to 25 days, of evaporation potential application.
