Soil temperature with depth (to 150‐cm) and time (April through September) was measured in field plots in North Dakota to determine the effect of three depths of wetting in late fall before freezing on the growing season soil temperature the following year. All plots were planted with spring wheat [ Triticum aestivum , ssp. vulgare (Vill., Host) MacKey var. Selkirk] and received identical treatment during the growing season. The data indicate that a high soil water content in the fall may cause soil temperature in the 30‐ to 120‐cm depth to be 1 to 2°C lower than normal during the next year's growing season, particularly if that season has lower‐than‐normal precipitation. By using soil temperature values from the 15‐cm and 120‐cm depths as the upper and lower boundaries, calculated soil temperatures agreed better with measured values than when 0.2‐cm and 120‐cm depths were used as boundaries.
