Several trial results were used in the research including spraying Silmet's liquid fertilizer on meadow foxtail sward in spring and summer, planting annual ryegrass before sowing and spraying it in summer. Amounts of liquid fertilizer in tests were 300, 450 and 600 l ha-1 (N60, N90, N120) Test results showed that Silmet's liquid fertilizer supports growth of grasses but causes damages while spraying herbage during growth period. Edges of leaves turned brown during spraying in spring. Using bigger amounts (450 l ha-1) caused larger damages both using pure or water-diluted (1:1) fertilizer. Heavy damage appeared in the day of spraying in summer. Leaves of damaged herbage and pinnacles of grasses turned brown. Yonger plants of herbage died in sward of annual ryegrass
