ABSTRACT:
Soil compaction caused by wheel traffic during planting and harvesting cannot be eliminated regardless of tillage system. Compaction during planting can cause increased runoff and soil erosion. Subsoil compaction during harvesting can cause poor internal drainage, delayed planting, loss of nitrogen, and lower yields. These problems are due in part to incomplete amelioration by natural forces over winter and may be amplified by some conservation tillage systems. In particular, continued use of no-till may not be feasible on fine-textured soils. Ways exist to minimize the detrimental effects of wheel-induced compaction, but some research needs remain, especially with respect to residue placement.
