A field experiment was carried out on black and sandy soil in order to estimate the influence of the addition of hydrogel Ekosorb on the content of water in soil, on frost damage of flowers and fruiting of strawberry. The results show that hydrogel used in a dose of 3 or 6 g dm-3 increased the amount of water accessible for plants in both types of soil, and yet the influence of the addition of Ekosorb was more visible in black soil than in sandy soil. The application of Ekosorb increased the number of flowers injured by spring ground frost in comparison to the control (soil without hydrogel). The higher was the Ekosorb dose, the more flowers were injured. The strawberry plants of ‘Elsanta’ were the most sensitive and of ‘Senga Sengana’ - the least sensitive to frost injuries. The highest yield of fruit, regardless of the type of soil, was obtained when hydrogel was applied in a dose of 3 g dm-3.
