CHAMPAIGN — Soil temperatures
remained below freezing across most of Illinois during the first
five days of March. That information comes from Jennie Atkins,
program manager for Water and Atmospheric Resources Monitoring,
known as WARM, at the Prairie Research Institute, Illinois State
Water Survey, University of Illinois.
Soil temperatures at 4 inches under sod averaged 31.6 degrees
statewide. Temperatures at 8 inches averaged 30.8 degrees.
For the period of December through February, soil temperatures
across the state at depths of 4 inches under sod averaged 33.7
degrees. However, the average was slightly elevated due to higher
December temperatures. For February, the average statewide soil
temperature at that depth was 31.6 degrees.
Soil temperatures varied greatly across the state. Southern
Illinois had an average soil temperature at 4 inches of 36.2 degrees
for December through February, which was 4 degrees higher than for
the northern portion of the state. The coldest temperature was seen
in west-central Illinois at Monmouth, which averaged 26.6 degrees
for the three months.
Low soil temperatures were also measured at 8 inches under sod,
with a statewide average of 33.4 degrees for the same period.
