Objective of investigations carried out on Stara Planina mountain (Serbia) during the period of 2003-2005 and 2008, was to establish the structure of plant associations, share of species in two major families, grasses and leguminous plants. Their presence is indicator of the quality of grassland and specific soil qualities, based on which agro-technical measures can be adequately implemented, especially mineral fertilizers. Realization of the goal directly influences increase of production of milk and meat, as well as final dairy and meat products, by applying the standards of ecological agriculture. Total of 8 associations were analyzed, and two of them Agrostietum vulgarae Z.Pavl. 1955, sensu lato. and Festucetum vallesiacae Borisavljevic 1956, occurred repeatedly on several location and different time interval of analysis. Number of species in analyzed associations was from 34 to 77. Beside number of plant species also their share categorized into categories of high quality grasses, high quality leguminous plants and useful species from other families, as well as harmful i.e. weed species. Main quality parameters were established in samples from all associations.
