The semi-natural grasslands in Romanian mountains are particularly important for the sustainable development of this region. Therefore, the objective of this paper was to evaluate the effects of mineral and manure fertilization upon the sward in order to recommend certain versions which have minor repercussions upon the plant diversity. In this study, we examined the influence of organic and mineral fertilizers on the production, biodiversity and quality of green fodder. The experiment was set up in mountain grassland of Festuca rubra L. and Agrostis capillaris L., during five years. In the experiment was evaluated the effects of management treatments on productivity, biodiversity and quality of the forage grass. The rate applications of fertilizers determine the number of species and the rate of production. The small quantities of organic and mineral nutrients (10 t·ha-1 manure and 30 kg·ha-1 nitrogen) can lead to larger yields while at the same time, improving biodiversity conservation and the quality of forage. Using a low input-based management system can be a solution that will lead to higher yields and contribute to biodiversity conservation and the good quality of the forage. In conclusion the use of a fertilizer management regime based on small quantities of organic and mineral nutrients can lead to larger yields while at the same time, improving biodiversity conservation and the quality of forage.
