ABSTRACT: This scientific work presents naturals conditions in Dragasani vineyard (relief, water – table and climate).The soils is descripted from morphological, chemical and agro-chemical aspects. Being a paper made on several analytical data of laboratory, there were used methods of specific interpretation to each of the two soil types analyzed, focusing on the physical data and on the chemical characteristics, especially on the Chlorotic Power Index (CPI) and iron content to determine the potential phenomenon of chlorosis – ferro-calcium, which are prone to such soils. The table number 1 and 3 present analitical date of the calcanic erodisol and calcanic regosol. The first map presents geographycal position and the second map represents soils cover in the Dragasani vineyard. Granule dominant faction in both soil types investigated is clay (percentage exceeding 43.8 % to 51.8 %). Mineralogical is the smectic clay mineral which favors certain conditions, triggering landslides extensive (that could move in its displacement, on slope, entire rows of grapevine). Consequently, some aspects of support factors creates vineyard inconveniences (clay texture, eroded slopes, acidification and so on), but these are filled climatic or anthropogenic remediated.

Keywords: soil, vineyard land, calcanic regosol and erodisol
