- Opis:
- Floristic and phytosociological studies were conducted on drained managed and unmanaged meadows occupying organic soils with a different moisture content. Soil samples were analyzed to determine their physical properties and the concentrations of total nitrogen, phosphorus and potassium. Phytosociological data were collected in 20 relevés representing different vegetation layers. A list of plant species was compiled and cover coefficients were calculated using the five-point Braun-Blanquet scale. The uppermost horizon of organic-muck soils had an acidic reaction, a high content of phosphorus, calcium and iron, an average cooper content, and a low content of potassium, magnesium and zinc. Managed hay meadows were dominated by the following valuable grasses: Alopecurus pratensis, Festuca rubra, Phleum pratense, Poa pratensis and Dactylis glomerata, accompanied by leguminous plants, herbs and weeds. Grassland abandonment led to undesirable changes in sward composition and contributed to the introduction of species with poor nutritional quality, such as: Avenula pubescens, Holcus lanatus, Deschampsia caespitosa, Elymus repens and Anthoxanthum odoratum.
