4inch hi/lo soil temps on 24 Nov 2003
4 inch soil temperatures as reported by the ISU Ag Climate Network indicate that the soil is still not frozen at the 4 inch depth. You may wonder why this is important. It is best for most plants for the soil to freeze once and then thaw in the spring. The cycling of freezing and thawing can be tough on crops like alfalfa.
