Technical Abstract: Soil compaction due to wheel traffic and tillage is an issue in soil management and crop production. This article describes a new approach to measuring compaction that provides data more efficiently than previous approaches. An instrumented shank pulled through the field by a tractor takes measurements at multiple depths. That data can then be used to generate multi-layered soil strength maps that indicate compaction differences. A future use of these soil strength data may be to control site-specific and/or variable-depth tillage to address localized compaction problems.
