The studied geographical area is situated in the north-western part of the Vlasia Plain and represents a fragment of the Dimbovita-Colentina flow. Morphologically, there are three relief types: the field, the terrace and the Dimbovita waterside. They differ from the parent material point of view (loess deposits within the field and alluvial deposits for the terrace and waterside), of the ground water level and morphologically. Brown-reddish soils are characteristic for the field (typical and mollic soils), mollisols for the terrace (Cambic and argillic chernozems), most of them influenced by the ground water table and also a few argillic soils (Brown argillic mollic soils, local Brown-reddish soils) and undeveloped soils for watersides (protosols and alluvial soils). Classifying lands taking into account the restrictive factors for arable lands, led to the definition of four categories of areas, but the prevailing ones are those belonging to the 11 and 111 classes. The main agropedoameliorative needs refer to scarifying and deep loosening operations for saucers and microdepresions, to levelling and exploitation operations and, locally, to liming operations.
