摘要

The paper presents the results of the analyses of selected physicochemical properties and the activity of alkaline and acid phosphatase in the soils which differed in terms of plant cultivation technology. Profile sI represented arable land in the crop rotation with cereals dominating (medium intensive technology), without irrigation, while profile sII-represented arable land with vegetable crops cultivation (intensive technology), intensively fertilized and irrigated. The content of available phosphorus in the two soil profiles investigated ranged from 6.6 to 69.1 mg/kg. The highest contents of phosphorus available to plants were reported in the plough horizon of both soils, while the abundance of potassium and magnesium was highest in the illuvial horizon of both soils. The soil profiles investigated showed a significant variation in terms of the cultivation technologies applied. The contents of plant-available Cu and Zn in soil were low and they resulted in the inhibition of neither alkaline nor acid phosphatase. The intensive vegetable crops cultivation technology decreased the content of organic matter and increased the content of the nutrients in soil. Using the Ward method, it was found that relatively similar physicochemical and chemical properties were reported for the genetic horizons of both soil profiles, especially Ap horizon of the soil representing arable land with intensive cultivation of vegetable crops.
