Sažetak
This investigation was conducted in eastern Croatia, where lowland area is substantially changed by agriculture. Cultivated plants replaced stable plant community of mixed forest consisted mainly of Quercus robur and Carpinus betulus. Dehydrogenase activity (INT) and selected environmental variables (pH, moisture, electrical conductivity, soil organic matter) were determined in two types of soil (chernozem, luvisol), two soil horizons (5-10 cm, 55-60 cm) and three types of plant cover (corn, sunflower and forest soil). Seven random samples were collected from each combination of soil and plant cover and from both horizons during September 2013. Three-way permutational multivariate analysis of variance provided evidence about differences between tested factors. As expected, most significant difference emerged between soil horizons, then between soil types and between types of plant cover. By further investigation of interaction effects the differences between plant cover types at different soils became evident. The forest was always different from crops. Between-crop effects were not evident in chernozem at both horizons. Yet they were present in luvisol at both horizons, and sunflower had positive effects on all measured soil properties compared to corn. Crop effects compared to forest were higher at the surface horizon in chernozem, but in luvisol were higher at the deeper horizon. Results suggest that regarding measured soil properties, there was no difference between soil usage for crop production in chernozem, but it was better to use luvisol for sunflower production. Future investigations should examine are there any effects on aboveground biomass. These results could help planning agricultural activity in soils of different nutrient status, especially in soils of low quality.
