Variable depth tillage has the potential for economical and environmental benefits to modern crop production. Varying depth according to local soil conditions prevents the waste of energy and preserves soil ecology. A proposed instrumentation system is based on a conventional straight standard for deep soil tillage. It allows real-time assessment of variation of soil mechanical resistance with depth, and can serve as a guidance sensor for proper tillage depth adjustment. Two linear pressure distribution models were used to predict the depth of a soil layer with local maximum of mechanical resistance (hard pan).
