Název v původním jazyce

The influence of long-term fertilization on species diversity and yield potential of permanent meaodw stand.

Popis výsledku v původním jazyce

Observations were realized on a plane meadow of a mesophyte character in 1976 - 2000 years. Four variants were observed in the experiments (0 - P40 K100 - N100 P40 K100 - N200 P40 K100) in four replications. Species composition of grass stands was variable in the followed period in the leaf area from 66 to 95 % of the dominance (Tab. I). Total abundance of species with PK -fertilization was almost identical in individual pentads (24 - 28 species) as it is evident in Tab. II. Table III proves the highestdominance was fonded at Dactylis glomerata L. in the first five years. Rhizomatous grasses had the highest leaf area with 38 - 55 % of the dominance on variants with the higher N doses (200 kg N/ha) + PK (Tab. IV). Tab. V demonstrates that the variant without fertilization showed nearly stable abundance of species with the higher than 1 % (11 - 13). Reduction of species number especially with the dominance higher than 1 % (5 - 11) followed at the highest N -fertilization in comparison w
