INFLUENCE OF SOIL AND FERTILIZATION ON THE PLANT COMPOSITION IN A PERMANENT GRASSLAND

This investigation was carried out (HBLFA Raumberg – Gumpenstein) on a sandy forsetsoil with differently kind of fertilization and cutting regimes on permanent meadows. This paper focuse on influence of grassland management on plant composition with special regard to herbs. Extensive management leads to an increase in herbs. The main reason is an open sward, leading to many gaps. Fodder quality is medium in these species-poor stands. Intensive management practices leads to an increases in the proportion of grasses and several herbs which are adapted to increased management intensity. Fodder quality increases, except of a high degree of coverage by Poa trivialis. Highest plant species richness is related to moderately management practice. Species richness will decreases both extensive and intensive management in a long-term.
