Illinois’ milder winter soil temperatures may have an impact on pest populations, according to researchers at the Prairie Research Institute at Illinois.
Overall, soil temperatures were milder than normal, according to Jennie Atkins with the Illinois State Water Survey’s Water and Atmospheric Resources Monitoring Program. At depths of 4 inches under bare soil, temperatures averaged 35.2 degrees this winter, or 1.4 degrees above the long-term average. Soils averaged 1.8 degrees cooler than last winter.
