| Four instrumented subsoilers were developed for alleviation of compaction on agricultural land. Draughts and soil disturbance of the subsoilers were measured during operation at the outdoor soil bin. Straight shank subsoiler (SSS), semi-parabolic subsoiler (SPS), parabolic ‘C’ shank subsoiler (CSS) and winged subsoiler (WSB) were designed and constructed for use by the tool carrier in loosening soil hard pan. Soil cone penetrometer (CP40II, 333 mm3, 60o cone tip angle) and electronic moisture meter were used to take readings at various locations and depths on the soil bin before and after subsoiling. Soil samples were taken to laboratory for analysis for physico-chemical properties. Each of the shanks was hitched to the tool bar of the carrier. A 100 kN... |
