GENERAL CHARACTERIZATION OF THE MAIN SOILS IN OLTENIA AREA

POPESCU CRISTIAN

Abstract


Situated safely under the Carpathian chain, between the Danube and river Olt, the geographical area of Oltenia presents a wide natural frame, witch determined a great diversity of the pedological cover, forming a true natural soils museum.

In the plain area, on the plateau, on loessoid deposits were formed and chernozems are met. Continuing the chernozems, on more humid areas, covering almost entirely the area from steppe to forests, there are present the cambic chernozems and argic chernozems.

In the southern central area of the region, determining from pedogeographical point of view the transitional type between argic chernozem and preluvosoil from the hill area, there are present the reddish preluvosoil and luvic reddish preluvosoil.

          The preluvosoils, luvosoils and albic luvosoils, are spread in the hill and table-land area, assigned according to the relief, rock and vegetation.

          On well drained plane field and on rocks rich in alkalescent elements are prevailing the preluvosoils, on plane, lowlands and acid rocks the luvosoils and albic luvosoils are formed.

          In the mountain area, the soils repartition is keeping a certain vertical areal, determined especially by heights. The eutricambosoils are met on the well drained  slopes and on eruptive rocks with a lot of alkalescent elements and the districambosoils were formed on rocks poor in alkalescent elements, of heights between 600-1000 m.

          At higher altitudes prepodsoles were met on gentle peaks and acid rocks, podsoles were met on the highest platforms and lowlands on acid rocks, and in the alpine area on a relief formed by plateau, gentle slopes and long ridges were met the humosiosoils.
