Abstract

The soils identified within PiscuVechi and Ghidici communes from the South-Western part of Dolj District have been classified in four classes, namely, protisoils, chernisoils, cambisoils and hydrical soils. The less evolved soils from protisoil class, sandy soils and alluvial soils, with different subtypes and varieties are suitable as arable, they can be cropped with majority of plants after specific measures of reclamation. For these soils there have been established the suitability classes as arable IV, respectively III. The chernisoils with different subtypes and varieties of chernozem have been classified in I st , II nd and III rd classes of suitability as arable, in function of formation and evolution specific, mainly due to parental material, the depth of the underground water and the alluvial process. All chernozem units can be used as arable, along with specific measures of improving their genetic fertility. The eutricambosoilsare less encountered in the studied area and the sandy eutricambosoil that has been identified within this area belong to the II nd class of suitability as arable. It suits without restyrictions for all crops; its fertility could be improved by balanced mineral fertilization and by irrigation. The gleyc soils class, by its specific soil into this area, the molliccalcaricsalsodicgleyc soil, belongs to the IV class of suitability as arable due to underground water at low depth and alkaline reaction. If they are not ameliorated, these soils have major restrictions for use as arable yet by applying hydric amelioration measures they can be cropped.
