The paper aimed to present the analysis of the qualitative changes in feed obtained as a result of fertilization with UAN liquid fertilizer of Festuca rubra - Agrostis capillaries. The experiment was established in 2014 in the Baisoara Mountain village (Cluj county), at the altitude of 1240 m about sea level. The experience includes four variants in three repetitions, which are: first variant (V1) – control variant (unfertilized); the second variant (V2) – fertilizer with 50 kg UAN/ha-1; third variant (V3) – fertilizer with 75 kg UAN/ha-1; fourth variant (V4) – fertilizer with 100 kg UAN/ha-1. The grass was cut once in 2014 and in 2015, botanical composition were determined and also feed quality. The natural meadow of Festuca rubra L. and Agrostis capillaris L. responded very well to the application of the liquid fertilizer. The use of liquid mineral fertilizer (UAN) can be taken into account in mountain conditions at moderate doses of up to 75 kg/ha of active substance applied at deworming. The floral composition evolving over the dominance of Agrostis capillaris L. with Festuca rubra L., which produce good quality hay.
