The featured chart shows the daily time-series of four inch depth soil temperature for each of the past 25 years for the Ames ISUAG site. The series for this year and last year is highlighted. Soil temperatures this time of year are in the cooling down phase as solar input decreases with each passing day and night time hours increase. This year's series shows the cold temperatures through March and the very cold temperatures during the snowfall in early May. Air temperatures are expected to get very cold next week, which will help soil temperatures cool more as well.
