The study of the influence of drip irrigation on electrophysical parameters and water-soluble salt content in soil and strawberry plants (petioles and fruits) under different fertilization systems is presented. The mineralization and pH of the water used to irrigate the strawberries were measured. The increased content of water-soluble sodium cation salts in irrigation water leads to soil salinization (typical chernozem) and an increase in its amount in the thickness of 0-50 cm during the study period. At the same time, the electrical conductivity of the soil-water suspension decreases. Water pH and salt pH tend to change to an alkaline reaction. The highest amount of calcium, sodium and potassium cations is found in the plants of the control variant, the lowest - in the mineral and organic-mineral variants, and the intermediate amount - in the organic system of fertilization with drip irrigation. Adjusting and regularly monitoring the salinity and pH of irrigation water will help grow healthy and beautiful plants, and plant sap analysis complements soil solution analysis.
