Abstract: The both possibilities and management ways of improving well-composed sowed sward and a natural sward were investigated during 2004-2005 at the Research Station of Lithuanian University of Agriculture. The aim of this study was to determine the impact of monomial N, P and K fertilizers, their combinations and rates on improvement of floristic composition of well-composed sowed fodder sward as well as on a natural, not improved for more than 10 yrs sward of poor nutrient value. The data of floristic composition of sowed and natural swards are presented. It was found that share of legumes in sowed swards decreased and share of grasses increased in the 3rd yr after sowing irrespective of fertilizing background. The increasing of legumes share in these swards was not determined by any treatment. The share of grasses increased from 4 to 14 %. The share of legumes ranged 4-12 % higher in P and K background to compare with other treatments in 2005. In the 3rd yr after sowing the percentage of legumes decreased sequentially with increasing N rates. The biggest share of legumes remained in treatments with P medium rates, K background supported legumes persistence to lesser extent. Impact of fertilizer background on floristic composition had the same tendencies in natural swards as in sowed one
