Influence of manure on productivity and quality of a meadow of Festuca rubra L.

Researchers current concerns are to maintain the high floristic biodiversity, enabling sustainable development of natural grasslands in mountain areas. Large surfaces of the Apuseni Mountains are fertilized with organic fertilization (these is the only way of fertilization used by grasslands owners), fact which causes probably the high phytodiversity specific for these area. Grassland management is the one who creates and maintains a high phytodiversity, being able also to reduce it drastically in a short time. This involves research at various levels of intensification in order to determine how productivity and phytodiversity of grassland evolves over time. The first studies conducted in the Apuseni Mountains were aimed to increase production and fodder quality through various technological methods (fertilization with organic fertilizers, amendment, overseeding etc.), without taking into account the specific biodiversity of phytocenosis. Currently the problem is changing radically and in all research actions undertaken is not overlooked the environmental dimension. Through this experience we plan to examine how different doses of organic fertilizers influencing productivity and fitodiversitatea of mountain meadows.
