Název v původním jazyce

Changes in the species diversity of grassland communities during secondary succession

Popis výsledku v původním jazyce

Treatments of N, P and K fertilization levels were studied over the course of 18 years (1992-2009) of secondary succession in a semi-cultural permanent meadow community of Sanquisorba Festucetum comutatae on a mesophytic site in a fodder production area.Results of the evaluation of species diversity levels show that on average only 23.7 species (max. 34 species) contribute to actual fodder production, i.e. only 44% of species ascertained. A high level of N fertilization - 180 kg.ha-1 year-1 - significantly lowered the number of species (average - 19.9) in comparison to the variant without NPK (25.3 species), as well as in comparison to PK (26.3) and 90 kg N-1 year-1 + PK (23.4). Grasses make up on average 43.0% of the total number of species, legumes5.9% and other herbs 51.1%. In the course of secondary succession, the number of species averaged across all treatments significantly increased, with 25.6 species in the 3rd post-stabilization phase (years 13-18) and 20.8 species in the 1
