Compaction will reduce crop yields by as much as 30-to-60 percent. “It is tire tracks so you don’t always see it,” said Jodi DeJong-Hughes, Regional Extension Educator, University of Minnesota. “It can be a hidden problem.” Wet soil is most prone to compaction and that is controlled by Mother Nature. “What farmers can control is their axle loads and the PSI of their tires.” Compaction can be found as deep as three-to-four feet. DeJong-Hughes spoke at the Soil Management Summit in Alexandria.
