ELEMENTS OF CORRECT FERTILIZATION OF THE MEADOWS IN THE HIGH PLAIN AREA OF BANAT ROMANIA

Abstract

The highly diversified structure of the vegetal carpet in permanent grasslands, made up of numerous plant species from various botanical families, also influences a strong differentiation in the consumption of nutrients by these plant species. Thus, species with high fodder value, are high consumers of nitrogen, and meadow leguminous species require higher consumption of phosphorus, calcium, and potassium. The area of permanent grasslands studied is located in the Banat Plain Romania, more precisely at the contact between the Banat-Crisana Plain and the Western Piedmont Hills. The general aspect of the relief is given by the presence of numerous steps of intense relief fragmented by a series of valleys that descend towards the Barzava river. A variety of grassland soils have been identified and the dominant soils are: eutricambosols, gleyosols and leptosols. The vegetation of meadow ecosystems develops in the moderate continental climate at the interference between the climate province sector with oceanic influence and the climate province sector with sub- Mediterranean influences.
