ABSTRACT
Extreme temperatures and drought are a natural phenomenon that have affected Southern Romania, with periods of severe drought in the periods: 1942-1946, when temperatures reached 61 degrees Celsius in the sun (1946), 1981-2001 and most recently in 2006 – 2007 [5].
Baragan Plain with the geographical position of Eastern Romanian Plain subjects it to the influence of an excessive continental type with average temperatures (T0C) of 10.50 to 110C, and an aridity index of 0.50 to 0.65, this being one of the most sensitive areas to soil degradation processes caused by drought, aridity and desertification.
In Baragan Plain there are soils with high fertility potential (such as typical chernozems, cambic chernozems, eutric aluviosoils and entic aluviosoils). The study on the vulnerability of these soils/terrains enables a more rigorous management of their use. Soil being the support for plant and development, a sustainable soil management is focused on biodiversity in different soil types, in an area where it has been gradually dwindling.
In order to achieve also the interpretation of the analyzed data, a large database was considered, that was taken from the concerned territory, however being made based on the methodology of developing soil studies written by the Research Institute for Soil Science and Agrochemistry, Bucharest.
The documentation is a key element, which is updated to soil-genetic processes and phenomena that pose problems for agriculture, given the natural environment.
The methods used for the determination of the soil types were done according to the Romanian System of Soil Taxonomy [7].
Soils grouping, was performed on soil types (sub-types) of soil, depending on soil and geo-climatic zoning of the territory of Romania [6]. The achieved soil profiles were analyzed in terms of size composition, respectively textural types according to the Methodology of soil studies elaboration, part - III, 1 average sample 1 to 5 ha distributed uniformly over the studied surface.

Keywords: types of soil, desertification, drought, vulnerability, degradation
