The GPS guidance systems are used almost in all field operations. In relation to the soil protection against erosion and compaction, possibilities to use other guidance systems are also looked for at present time. The heavy agricultural machinery across the field is a common practice nowadays; however they leave mainly random trails. As a result of this fact, soil is very often subject to repeated pass and therefore to irreversible structural changes of soil because of its compaction. According to literature sources and many experiments, soil compaction caused by repeated passages of agricultural machines across the field reduces its infiltrability, hydraulic conductivity, porosity, aeration and increases its bulk density and resistance to root development. The guidance systems and the Controlled Traffic Farming system, which are based on maintaining the same wheel track in a period of several years for each operation on the field, is one of the tools which can be used for soil protection against soil compaction.
