Soils in northern and
east-central Illinois are beginning to dry out after the rains of
last weekend, according to Jennie Atkins,
Water and Atmospheric Resources Monitoring (WARM) Program Manager at
the Illinois State Water Survey, Prairie Research Institute,
University of Illinois.
Soil moisture levels at 2
inches ended the first half of July with a statewide average of 0.30
water fraction by volume (wfv), slightly below the field capacity
for most of the soils monitored.
The highest moisture
levels were in northern and east-central Illinois with regional
averages of 0.35 and 0.38 wfv at two inches, respectively. These
areas saw up to 4.5 inches of rain on July 12 and 13. West-central
and southern Illinois had averages of 0.25 and 0.28 wfv,
respectively, still significantly above the wilting point of 0.14
At depths of 20 inches
and greater, soils were wet. Statewide levels averaged 0.38 wfv at
20 inches and 0.44 wfv at 59 inches.
Soil temperatures have
cooled over the past few days. On July 15, temperatures were below
normal with statewide averages of 74.0 degrees F and 72.7 degrees at
depths of 4 inches under sod and under bare soil.
