Current Production Potential of Permanent Grasslands per Vegetation Areas and Altitudes (Caraş-Severin County, Romania)

Abstract

Permanent grasslands in the Caraş-Severin County, Romania, cover, at present, 250,334 ha, i.e. 5.4% of the total grassland areas of the country. In this county, where grasslands represent 30% of the total area and 65% of the total agricultural area, permanent grasslands are important for the economy of the county both agriculturally, and socially and ecologically. Studies carried out show that the production potential of these grasslands varies between 8.51 and 13.14 ha of green matter; when applying complex mineral fertilisers, production increases three times and, when applying organic fertilisers, it increases two times. In general, after 500 m of altitude, green matter production decreases constantly with the increase of the altitude.
