Soil temperature monitoring may be useful for estimating potential pest pressure, frost depth, planting conditions, moisture infiltration, and soil biological activity, among other things; however, soil temperature is not a standard variable collected at most weather stations. Current daily average soil temperatures are in the upper 20s and lower 30s for most of Nebraska, at the 4-inch depth. Even though air temperatures set record lows this week, the abundant snowpack and soil moisture for most , kept soil temperatures warmer than one might expect. This may benefit over-wintering crops, but also pest survival. This provides a daily average and a seven-day average soil temperature at a depth of 4-inches through statewide maps and a table with each of the 67 Mesonet sites. The table provides an average, high, and low soil temperature for the previous seven days, as well as the most recent midnight reading. All of these readings are provided for a bare soil surface, but a few sites also provide comparisons to a grass covered surface. Available for Apple and android. Every Monday and Thursday the National Weather Service provides a map showing the depth of frost penetration, as well as the depth of frost thawed, in order to give you a visual of the frozen layer not temperature of the soil. Frost depth is measured by placing a small tube of water in a tube buried in the ground.
