The article presents the results of experimental studies of the influence of fertilization of sown grasslands on the density and dynamics of the botanical composition. It was established that the highest percentage of legumes (58 %) was obtained on the variant with red clover and birdsfoot trefoil with N15P60K90 + MAXPLANT fertilizer and a percentage ratio of grasses and legumes of 30/70 %. The largest share of grasses (61 %) was noted in the variant with full mineral fertilization, where the ratio of grasses and legumes was 70/30 %. Application of fertilizers + MAXPLANT has a positive effect on the content of legumes in the grassland. The share of legumes on average varies between 29–65 % in the first mowe and 34–63 % in the second. The percentage of grasses, on average, in the first mowe was 30–67 %, in the second – 33–65 %. The forbs that appeared was suppressed by the sown grasses and occupied an insignificant share. On average, the percentage of forbs on the sown grassland varied between 4–15 % in the first mowe and 2–5 % in the second
