Description
  • This paper deals with the influence of the level of fertilization on the species composition of semi-natural grasslands. This factor was examined in levels: not fertilized, fertilized PK, fertilized 90N+PK, fertilized 180N+PK. The other examined factor was relation to the intensity of use (duble-cutting, triple-cutting). Monitored factor influencing the primary production was as level of influence as weather conditions too. Evaluate growth is located at experimental habitat near village Kameničky. Evaluated years were: 1993, 1997, 2002, 2007 and 2012. Fertilization was done by mineral fertilizers. Cut was realized for triple-cutting at the beginning of June, September and October. For double-cutting in half of June and October. The results show that species composition of semi-natural grasslands declined with increasing dose of nitrogen. On the contrary, was growing (P<0.05) its yield and quality. This increase was mainly cause by grass species. Aplication of nitrogen fertilizer suppressed (P<0.05) herbs, but especially legumes. Aplication of phosphate and potash fertilizers supported the development of legumes. Triple-cutting use had a higher species composition, double-cutting growth had higher (P<0.05) yield and quality.
