Última Mechanical subsoiling: Mitigation of recompaction by light traffic and on-land ploughing Organic Eprints Munkholm, L.J.; Schjønning, P.. Plough pans have been shown to severely hamper root development, limit rooting depth and reduce crop yield. However, mechanically loosening of compacted subsoils often gives discouraging results. This has in many cases been related to a quick recompaction of the subsoil after loosening, as loosened subsoils are highly prone to recompaction. We evaluated the degree of recompaction of a mechanically loosened sandy loam. In addition, we studied the effect of plough pan compaction and subsoiling on root and yield response for a winter wheat crop. Plots were mechanically loosened to a depth of 35 cm in 1997 and again in 1998. Perennial grass/clover was grown with limited traffic intensity in 1999-2000. The perennial grass/clover was ploughed under in spring...
