Abstract
The windbreaks do not only affect the fertility of the soils of the adjacent territories, but also activate the soil-forming process in the stands themselves, which became the subject of the study. It was carried out on 6 trial plots located in pairs in classical windbreaks and windbreaks transformed into narrow linear stands of silvoarable agroforestry. Soil samples were taken in every 10 cm to a depth of 40 cm both in windbreaks and in adjacent fields at distances of 3 and 10 heights. Determination of agrochemical properties of soils was carried out in a certified laboratory using generally accepted methods in soil science. Soils in the windbreaks are in an undisturbed state, which indicates the predominance of organic matter in the soil compared to arable lands. Humus reserves in the windbreaks exceed similar indicators of arable lands by 10.7 and 3.4% at distances of 3Н and 10Н, respectively. A significant predominance of easily hydrolysable nitrogen in the upper 0-10 cm soil horizon in all windbreaks was found compared to its content in the lower horizons. A significantly lower nitrogen content was noted in the upper soil layer of transformed windbreaks compared to classical windbreaks. The greatest accumulation of phosphorus was found in the classical windbreaks in the upper 0–10 cm soil layer, where its supply was 156.80 mg/kg. In the transformed windbreaks, the phosphorus content in the upper soil layer was in all cases 11.4–14.5% lower compared to the similar indicator in the classical windbreaks. Significant accumulation of phosphorus was recorded in the arable soil layer at distances of 3 and 10 heights from the windbreaks, where its content ranged from 117.60 to 170.40 mg/kg, which is explained by the neutral acidity of the soil and its intensive cultivation. Soils under the windbreaks are characterized by an acidic reaction of the soil solution, where the pH takes on values from 4.64 to 5.50. The soil of the lower horizons of the windbreaks is characterized by lower acidity, which is a consequence of accelerated mineralization of organic matter. The acidity of transformed windbreaks soil is significantly different from the acidity of classical windbreaks soil with a trend of its decrease.
