Impact of grassland management and subsequent abandonment on floristic composition

Popis výsledku v původním jazyce

The aim of this study was to evaluate changes in floristic composition of permanent grasslands after the cessation of their regular utilization and organic fertilization. A long-term small plot trial was established in 2004 in locality Rapotín. During 2004-2012 the experiment was fertilized with compost and slurry, both with the range of stocking rates 0.9, 1.4, and 2.0 livestock units (LU)/ha (corresponding to 54, 84, and 120 kg N/ha). The plots were cut 2-4 times per year depending on given dose of fertilizer. During 2013-2016 the regular management was ceased and the grasslands were completely abandoned. Before the grassland abandonment, the highest total number of species (24 species) was found in the treatments regularly fertilized with compost. The dominance of grasses was influenced by the grassland management, with decreasing intensity of utilization the dominance of grasses increased. Four years after the grassland abandonment the species diversity in almost all treatments decreased and the dominance of grasses increased in all treatments, up to the value 67 – 80 %. Based on the data about the soil chemical parameters from two investigated years, our results suggested not only the effect of grassland management and its subsequent abandonment, but also a residual effect of the both organic fertilizers. These findings indicated not only the importance of the maintenance of regular grassland management for sustainable conservation of grassland communities, but also the importance of a reduction of nutrients, as the residual effect (mainly of organic fertilizers) can manifest itself for a long time.
