Interpretive Summary:

Technical Abstract: Crop yields are often hindered in the U. S. due to the presence of root- restricting soil layers and soil compaction. Preventing soil compaction through the use of appropriate cropping systems, reduced vehicle traffic, or tire selection can enhance overall soil quality and increase yields. However, many soils already affected by soil compaction need some tillage to temporarily remove this compacted soil layer. A uniform depth of tillage is an inefficient use of fuel due to the varying depth of this root-restricting layer. Preliminary results indicate that site- specific tillage may reduce fuel costs between 33-70% and improve yields up to 10%.
