The influence of habitat conditions on developing and floristic character of Arrhenatheretum elatioris community syntaxons in the Flinta valley (Central Poland)

Abstract
Differentiation of habitat conditions results in the development of areas of ryegrass grasslands of significant floristic variation and provides a basis for the distinction of lower phytosociological units. The paper contains a floristic characteristic of Arrhenatheretum elatioris syntaxons regarding their habitats. The aim of the study was a detailed characteristic of habitats including their phytosociological as well as soil properties. The analysis of 44 phytosociological relevés of ryegrass grass-lands areas enabled a comparison of their botanical and phytosociological structures as well as of their floristic diversity. Three subassociations were found in it: Arrhenatheretum elatioris typicum, Arrhenatheretum elatioris ranunculetosum repentis and Arrhenatheretum elatioris dactylidosum glomeratae. Furthermore, the paper contains a detailed description and interpretation of soil conditions. Two soil profiles were performed in mucky soils (Mollic Gleysols). In the samples collected from various genetic horizons, such properties were marked: pH, the content of carbon and total nitrogen, calcination loss, texture, soil density and particle density, total and drainage porosity, hygroscopic moisture and maximum hygroscopic capacity, potential of water bonding in soil and its total and readily available waters, total retention and filtration ratio. The examined soils were rich in organic matter and light texture of mineral endopedones which determined their high total porosity. Drainage porosity and filtration ratio were balanced and high, which gave good conditions for natural drainage. Water capacities, at each water bonding potential, were of similar characteristics to soils of similar texture.
