This study investigated the effects of soil salinity, soil depth, and seasonal conditions on catalase and dehydrogenase activities in irrigated takyr-meadow soils. The research was conducted in non-saline, slightly saline, moderately saline, and strongly saline soil variants at depths of 0–25, 25–50, and 50–80 cm. Enzymatic activity was determined during spring, summer, and autumn, and seasonal dynamics were comparatively assessed.
