Abstract: The aim of this study was investigate the impact of different soil tillage on physical-mechanical soil properties of different soil layers. Research conducted at the Lithuanian University of Agriculture Experimental Station loamy soil with five different tillage variants, using different tillage machines. After cultivation on different machines as follows: soil texture and water stability, density, moisture and hardness. The Experimental studies have established that completely uncultivated soil, soil structure stability of better than 11 % of conventional ploughing, the soil is better resistance to heavy loads. It is also less likely to cause soil erosion. Soil hardness in deeper layers (50 - 80 cm), uncultivated soil was lower (about 1,0 MPa) compared to other tillage variants. Using minimum tillage (shallow ploughing, disc harrows, deep weeder) can save more water (4,7 %) in the upper soil layer compared with conventional tillage. Increased soil moisture content allows on spring to improve seed germination conditions. Exploration of the soil density was observed that the fundamental difference between the different tillage machines not found
