摘要：The study examines the change in the properties of biochar obtained from Betula alba tree residues after its application in a field growing experiment for two growing periods in the areas with different water-air conditions (both with and without drainage). The results obtained after the first growing period showed a noticeable change in the indicators. The pH values in the biochar sample after the first growing period decreased sharply by 1.3 and 0.7 units in the areas with and without drainage, respectively, compared to the initial pH value of 8.09. After the second growing period, the change in pH value was not significant. The values of ash elements increased sharply, the content of volatile compounds decreased slightly. Water retention capacity improved. After the first growing period, water retention capacity almost doubled and it changed slightly in the sample with the biochar after its application in the second growing period.
