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). INTRODUCTION Soil is subjected to continuous degradation due to climate change, floods, acid rain, intensive and inappropriate works, for which almost all governments of the world are trying to take measures in order to protect soil by appropriate conservative measures. One of the main factors leading to soil degradation is compaction [1, 2, 3, 4, 7, 13, 15, 19]. The reason for increase of soil degradation by compaction is largely due to the increased mass of agricultural machinery and tractors (due to the desire to increase the working capacity), the intensive use of agricultural machinery even in unfavorable soil conditions, the desire for higher yields (when are performed more operations of hoeing, herbicide, irrigation, etc.)
