The influence of drip irrigation on chernozem soil agrophysics to a large extent depended on the soil moisture pattern. At the end of irrigation season an area formed in the upper layer (0-20 cm) at a distance of 20 cm from drip line contained high amounts of salts such as water-soluble salts, nitrates, carbonates. Calcium salts prevail among water-soluble salts. Soil exchange complex saturated with absorbed sodium up to 14%. Physical soil properties deteriorate generally because of predominance of blocky fractions under "dry" sieving; water-resistance – extra high. It was noted the deterioration of microstructure at a distance of 20 cm from drip line according to Bayver extent of aggregation. In spring content of water-soluble salts, nitrates and absorbed sodium substantially decreased.
