Abstract

The pastoral area of Romania, covering of over 4.8 million ha, has been influenced, over the last decades, by natural and human factors, which affect the normal functioning of the grassland ecosystem. The aim of this paper is to point out the dynamics of phytocoenotic biodiversity, as a result of applying grassland technical measures, in order to improve the yield and quality of grassland ecosystems with minimum effects on the environment. Therefore, the main aim of our study is to establish a positive relationship between biodiversity and the optimum quantity of organic fertilizers, which would improve the quality and quantity of the yield, without diminishing the floristic biodiversity. In the case of the studied grasslands, the phytocenotic biodiversity is influenced by the type of fertilization, the used rates and by the soil and climatic conditions. These grasslands may be improved by manure fertilization and reasonable usage, if proper management is applied. In Gradinari, Caras-Severin county, the dominant species are Festuca rupicola and Calamagrostis epigeios, in Magurele, Brasov county, Agrostis capillaris, Festuca pratensis, Poa pratensis and Trifolium repens, and in Pojorata, Suceava county, Agrostis capillaris, Trisetum flavescens, Trifolium repens and T. pratense species. The highest number of identified species (43) has been recorded by the meadow made up of Agrostis capillaris and Festuca rubra, from Pojorata, Suceava county.
