Annual Soil Temperature Wave at Four Depths in Southwestern Wisconsin

Abstract

Soil temperature was measured for a year on a southeast-facing slope of 25 percent, latitude 43 degrees 50 minutes N. The spring-summer cover was unmowed alfalfa-bluegrass meadow, the fall-winter cover, meadow stubble. Snow cover was light or absent. The soil was Fayette silt loam, valley phase. The annual temperature wave at all depths followed the air temperature wave. The annual range in soil temperature varied from 30 degrees C at 15 cm to 17 degrees C at 120 cm. The lowest soil temperature was -7 degrees C
