THE DISTRIBUTION OF SOILS AND FOREST SITES IN THE TURKEY OAK AND HUNGARIAN OAK STANDS OF OLTENIA PLAIN
The main objective of this study is represented by the analysis of the Turkey Oak and Hungarian Oak stands in the Oltenia Plain, considering the edaphic and site conditions, based on the data from the forest management plan. This analysis was possible as the forest management plans describe the forested lands and they also realize a very detailed description of the forest stand, which is an homogenous land surface from a site point of view. The study researched, based on a large amount of data from the forest management plans, the edaphic and site conditions in the Oltenia Plain, reflected by the forest soil types and subtypes, as well as the site types on which the Turkey Oak and Hungarian Oak stands grow. Thus, it was observed that the soil types on which the Turkey Oak and Hungarian Oak stands in the Oltenia Plain are growing belong mostly to luvisols (80%), of which the majority are reddish luvisols and reddish-vertic luvisols, both with 24%. The great diversity of the geomorphological, geological, climate and soil conditions which describe the studied area (Oltenia Plain) led to the identification of 13 forest site types, grouped into two physio-climatic regions (forest plain and forest steppe). The most common forest site types are : Forest plain of Turkey Oak-Hungarian Oak Pm, brown and reddish brown podzolic, diverse pseudogleyzed middle edaphic (code 188.8.131.52.), which represents about 36 %, followed by Forest plain, podzolic pseudogleyzed III/III-II, with 31%. It was also observed that superior index forest sites represent more than half of the studied area (55%), the middle index forest sites represent 32 %, while the inferior index forest sites represent 13 %.
