1. Introduction
Agricultural production systems tend to increase the number of passes and the loads carried on agricultural vehicles, resulting in a potential for increased soil compaction (Newell-Price et al., 2013).
According to the EU Commission, soil compaction is recognized as one of the main factors that can lower crop yields and thus has become a serious agricultural problem (European Commission (EC), 2006).
Compaction leads to soil structure degradation, which results in a deterioration in physical properties. Associated with
this bulk density and soil strength, measured as penetration resistance, are increased (Richard et al., 2001; Pagliai et al., 2003; Hamza and Anderson, 2005).
