RESEARCH REGARDING THE IMPROVEMENT OF MOUNTAIN MEADOWS IN RANCA AREA, GORJ COUNTY

Abstract

Our country has 4.82 million hecare of meadows, of which 3.34 million are used by grazing. Gorj County is occupied by meadows on almost half of the surface, the meadows in the mountain area being the most intensely exploited. The Rânca area is positioned at altitudes of 1350-1680 m, in the upper part of the boreal floor. The average annual temperature is about 5°C, and the rainfall exceeds 1,000 mm annually. Under these conditions, on these surfaces were installed meadows ecosystems with limited potential of production and quality of feed, such as those of Nardus stricta L.. The research carried out in the agricultural year 2024-2025, within the Research base of the mountain meadows belonging the University of Craiova, Faculty of Agronomy, aimed at quantification of the effect of different types of fertilizers on the biodiversity, productivity and quality of the feed on a Nardus stricta L. meadow. Ferilization with complex solids mineral fertilizers, NPK type, led to an increase in the percentage of grasses species and a decrease in the varous species and to an increase in the production and feed quality of Nardus stricta L., meadow. Also, fertilization efficiency had the maximum value in thys case.
