The capacity of a winged subsoiler to modify the physical characteristics of compacted soil layers was studied in sandy loam and clay loam plots subjected to 0 and 1 subsoiler pass, and 0, 1 and 2 subsoiler passes, respectively. The depth of loose soil, dry bulk density and soil moisture content were used as indicators. U-shaped soil disturbance patterns were observed. It was found that subsoiling compacted the top soil while loosening the subsoil. Both effects were more extreme after two passes.(Download PDF) (Export to EndNotes)
