Oro slėgio padangose įtaka dirvos suslėgimui

One way to reduce soil compaction is to reduce agricultural machines vertical load, thus reducing the weight of the machine. But the weight of the machine can be reduced to a certain limit. One of the ways to streamline the distribution of load on the soil - to change the air pressure of the tires allowing on the soil physical and mechanical properties. Investigations were carried out before the autumn sowing a light sandy loam field. Before the study soil was plowed at 20 cm depth. Soil moisture at a depth of 5 cm was 12%. The studies found less than 19 MPa soil pressure at 0.5 bar pressure in the tires, soil hardness was less than 4.8 times, at the 5 cm depth and at the sole of arable pad less than 4.1 timeVytauto Didžiojo universitetasŽemės ūkio akademij
