%X Soil characteristics can exert an influence on the development of root systems, mineral nutrition, providing the required heat treatment and conduct aerohidric main physiological processes, and plants (phytocoenosis, in turn, act both directly and indirectly on the state of soil fertility). In the soil conditions can be defined certain characteristics that may be conducive to land productivity and other properties derived from the first. Attributes such as size and composition of soil, humus content are crucial features, while cationic exchange capacity is determined by the first two and by the mineralogical nature of clay. Similarly, available water capacity can be considered as determined by soil texture and structure. Our research concerns an area of 141,249 ha. (72721ha. in Timis county and 68,528 ha in Arad county), belonging to areas located in Vinga Plain and its connection to the low plains or Lipova hills. The research of ecopedological conditions, data ordering and processing was done according to the Methodology of pedological studies elaboration; (vol I, II, III), developed by ICPA Bucharest in 1987 and the Romanian System of Soil Taxonomy (SRTS-2003). In assessing of land pretability for culture systems are considered soil factors who determine the degree of suitability, soil texture and soil moisture excess. Pretability estimation can be based on the information contained in existing soil studies in the area but also in the field research conducted on soils representative of a particular physical and geographical space.
