The frost-free period is 100 to 165 days. These are the Bakeoven, Lickskillet, Valby and Wrentham soils and the competing Cantala soils. All of these except Valby and Cantala soils contain more than 35 percent fragments. Also, Bakeoven and Lickskillet soils are less than 50 cm deep to bedrock. Valby soils are calcareous at depths of 38 to 76 cm.
