ABSTRACT This diploma thesis is valuating an influence of a nitrogen fertilization on species structure of a semi-natural grassland. Experimental site is located 650 m in the Bohemian-Moravian Highlands in locality of Kameničky. From 2012-2013 four variants of fertilization has been compared (unfertilised, fertilized 45 kg.ha-1 N + PK, fertilized 90 kg.ha-1 N + PK, fertilized 135 kg.ha-1 N + PK and fertilised 180 kg.ha-1 N + PK) and two variants of fertilizers (two-edged and triple-edged). Additionally, I am dealing in detail with outproductive functions of permanent grassland and analysis of individual plant species represented at the observed site. All the obtained results show, that species diversity decreases with fertilizers, which on the contrary increases production of fodder. Fertilising with N increases (P<0,05) proportion of cultural grasses, but simultaneously decreases (P<0,05) proportion of herbs and clovers. Regarding intensity of utilising, fertilisers triple-edged were more species diverse, a diversity index confirms this fact.
