Agricultural Soil Compaction Under the Action of Agricultural Machinery

Abstract

Artificial compaction of agricultural soil consists in the increase of soil bulk density, respectively in the decrease of soil porosity, especially due to the contact with the tires or tracks of tractors and agricultural machinery. This paper aims to determine the pressure on the soil, by simulating real field conditions in the laboratory. Experiments were conducted using a complex testing system in accelerated regime, which can simulate the static pressure at compression of the tires on the soil (stationary machinery). For each experiment were taken into account: the dimensional characteristics of the tires, testing conditions in operation and also the dynamic characteristics of the tires (when tested in real conditions).
