Abstract:A study was conducted to investigate a different arrangement of prismatic tips on a tine for on-the-go measuring soil mechanical resistance at various compacted soil layers in the soil bin. In order to do this, four prismatic tips with apex angle of 30º and base area of 323 mm2 were mounted horizontally on a tine face and then connected to load cells. The length of shafts was reduced from top to down the tine. The developed system was evaluated in a controlled soil bin laboratory conditions with clay loam soil and uniform soil moisture content. The experiment was designed with soil compaction at three levels of uniform and three levels of non-uniform in completely randomized block design with four replications. Vertical standard penetrometer was also used to compare with horizontal sensor data at whole working depth of 0 to 400 mm. The results indicated that there was a correlation with R2 = 0.88 between soil cone penetrometer and the horizontal multi-tips sensor data. It can be concluded that the idea of reducing the length of the tips from top to down the tine face would give promising results.
