Review of different agricultural machineries chassis influence on soil compaction and environmental pollution

Soil compaction due to uncontrolled field traffic and using heavy machinery is most common degradation type for Europe. Nowadays, world organizations such as the UN are paying more and more attention to it. And it’s very helpful. Also, compacted soils have negative effect to environment, for example it can lead to erosion, landscape degradation, additional air and water pollution. Reviewing and analyzing the information sources on the effects of various wheels and tracks on soil compaction and environmental pollution is basic method of this study. Chassis type and others parameters of agriculture machinery has a significant impact to soil and it degradation processes, for example compaction. Soil compaction after using different tracks and wheels is not the equal, it can be concluded after comparing various research result. Soil stress modeling or direct measurements are used to evaluate compaction. Modeling shows well the tendency to spread stress, but usually only vertical stress is evaluated. According to different studies soil stress for close soil moisture, close soil structure, at various depths. For 0.15 m single wheels has vertical stress 150 kPa, dual − 80 kPa, rubber tracks − 60 kPa. The trend persists with increasing depth, confirmed by other experiments measuring or simulatedAgronomijos fakultetasVytauto Didžiojo universitetasŽemės ūkio akademij
