ABSTRACT
The paper presents results of studies on some mechanical and tractive properties of the soil on the basis on which an analysis was made of the range of their changeability. The plants on which the studies based were peas, winter triticale, sugar beet and winter wheat cultivated by means of traditional methods and a simplified method, which is without ploughing. Comparable values of the yields were found out. Higher values of soil compaction and the maximum contact stress occur in the soil cultivated in a simplified method. Fluctuations of these parameters were observed during the period of vegetation and these were gradually leveled during the harvest. However, it was related to the course of the weather, and especially the soil humidity. The studies showed a relation between the examined technologies of soil tillage and the values of the obtained tractive forces.
Key words: tractive force, compaction, maximum contact stress, soil tillage technologies.
