Abstract. Soil has an important role in sustaining life on earth and represents the support for the practice of agriculture, which provides the population’s food security and safety. Preserving the land production potential and ensuring a durable development is a key factor in the present times. In this context the researches presented in the paper analyze the effects of soil compaction and of the type of tillage machinery over some soil properties for autumn wheat crop set up. Twelve experimental variants were considered, based on two influencing factors: factor A = soil compaction, with 3 variants; factor B = tillage machinery system, with 4 variants. The following indices were taken into account for each experimental variant: apparent volumetric mass, penetration resistance and stability of the soil structural elements, expressed by the means of two indices: weighted average diameter and water stability of the aggregates. The results of the experiments regarding the effect of soil compaction and tillage machinery system led to the conclusion that the technological variants that create favorable conservation conditions were the ones leading to minimum soil compaction, obtained through direct seeding into the stubble and no plowing.

Key words: Soil compaction; Tillage machinery; Autumn wheat crop; Soil physical properties.
