Adaptation of a trafficability sensor on large agricultural machines to test the current trafficability with regard to soil conservation
General assessments for the compaction sensitivity of soils are existing. The machine driver needs information about the actual compaction sensitivity of his fields for a soil conservativetrafficking, which by means of modern sensors has to be considered.
The main goal of conservational soil protection is to reduce soil pressure. Among the technical solutions is a trafficability sensor, which among other things displays on-line measurements of track depths of the current settlement of top- and subsoil and thus delivers a measurement for the current compaction risk for the soil. Therefore the track depth at the surface can be interpreted regarding the threat of soil functions.

An adjustment of vehicle parameters to the state of compaction takes place, for example, with a sonar sensor which adjusts the maximum deflection of the tires by altering the inner tire pressure. A hydrostatical soil settlement measurement, in addition to a soil pressure measurement, provides information about changes in the soil structure following a trafficking – elastic and plastic soil deformations are shown.
