Soil compaction can reduce crop yields.
Tractor traffic in wet soils is a major cause of soil compaction. Higher axle weights produce deep soil compaction. Subsoiling in the fall can alleviate soil compaction. Soil compaction in cultivated fields may have an adverse effect on crop production in Colorado. In intensively cropped irrigated cropland, soils that are frequently moist throughout the year often show the effects of extensive surface traffic causing soil compaction.
