Soil compaction response to wheel traffic in the Rolling Pampas region of Argentina


 The present work shows the effects of different agricultural wheels traffic on soil physical properties a Typic Argiudoll worked under no-tillage cropping system. Soil compaction produced by was quantified through these parameters: a) cone index, b) rut depth and c) water content at moment. Grain chaser, sprayer, harvester combine tractor equipped with commonly used in study area were tested. main results obtained showed that tyres highest inflation pressure tyre ground pressures values index depth. continuous system is not able to constrain topsoil subsoil when it wheeled greater than 77.6 kPa.
 Highlights
 causes reduction root growth yield many crops.
 does limit kPa
 When machinery load increases soils high bearing capacity (soils long-term system), problems increase.
