Estimation of usage and fertilization impact on quality of Festuca rubra pasture and sustainability of some technological variants

The purpose of this research was to study the effect of some treatments (fertilization, oversowing,cutting, grazing) on a Festuca rubra mountain pasture from Cindrel Mountains (MeridionalCarpathians, Romania), in order to improve the quality of this pasture. Yearly fertilization with organicfertilizers or moderate chemical fertilization (N100P22K83 kg ha-1 y-1) positively influence some soil chemicalfeatures, the nutritional status with N of plants and the level of forage yields of this pasture. Theamplification of N biogeochemical cycle in the variants fertilized with moderate dozes of N determinessignificant increases of quantity and quality of forage production.
