The objective of this study is to examine how the Danthonia alpina Vest type grassland changed as a result of fertilization in the hilly Balkan region. Unfertilized control and four fertilized treatments P60K60 (PK), N20P60K60 (N20), N80P60K60 (N80) and N140P60K60 (N140), were applied annually during a four-year period were examined. Mean Landolt’s ecological indicator values (moisture (F), nutrients (N) and temperature (T)), were calculated for each treatment. The fertilized plots showed higher F and N, but lower T value, and the changes became more evident at the fourth year of application. During the research period, the NxPK treatments had a greater effect than PK treatments. The F was highest in treatments N140 (2,97) four years after fertilizers were applied; Nevertheless, T decreased greatly in the fourth year and ranged from 3,40 (control) to 3,03 (N140). In our experiment, short-term fertilizer application changed Landolt’s ecological indicator values, which is the opposite of ongoing climate change effects.enCC0 1.0 Universalhttp://creativecommons.org/publicdomain/zero/1.0/grasslandDanthonia alpinaLandolt indicator valuesnitrogenarticle
