Soil and terrain favorability for grape-vine of a stagnic luvosoil from Cândeşti Piedmont, Ştefăneşti-Marcea Plateau.

Abstract

Ştefănesti township from Arges county is one of the most ancient and significant Romanian wine-growing regions. The wines created here have won local and world-wide appreciation. Plantations are placed both on the left slope of Arges river, where ample terrace systems and anti-erosional works have been performed, and on the piedmontan plateaus with clayey, vertic soils. The Arges County Soil Research Office has conducted a special soil survey research on Marcea piedmontan plateau in the summer of 2012. Consequently, a soil-profile was dig and the taken samples were analyzed in OSPA’s laboratory. The soil-profile is typical for most surface of the piedmontan relief and is placed within an entirely weedy plantation. Following the local examination and analytic interpretation, it results that soil’s taxonomy is stagnic aric Luvosol (Romanian Soil Taxonomy), resulting from a native stagnic Luvosol. Following the analysis of the main indicators regarding the soil-terrain system typical of the Ştefănesti Plateau, Marcea zone belongs to the 4th pretability class and to the third quality class. Main soil restrictions are acidity and the clayish texture. Because a system of improvement works can be emplaced, the soil has been evaluated and after an improvement of the natural coefficients. In these terms, the soil crossed into the third class of quality and remains in the same class of pretability for vineyard plantation. The paper shows that the studied area gathers most of the conditions needed for capitalization of lands through conversion and expansion of vineyard plantations.
