Research on the Physico-Chemical Properties of Soils Locality Daneasa, Olt County for Sustainable Agriculture

The territory studied is situated in the South-Eastern part of Olt County, it is part of the great unit of the Romanian Plain, that is, from the subunit of Boianu Plain (Calmatui Plain), being located on the left bank of Olt River. Locality presents a predominant relief of plain low altitude that is characterized by alluvio-proluvial plains moderately fragmented with local terraces, covered with loess-like deposit but relief of saucer. The soil cover of the territory under study is the direct reflection of all environmental factors, each having a role in the pedogenetic processes. Thus, the climate conditions have ensured the solification direction, taking into account the temperature regime and the specific precipitation of the Boianu Plain. Steppe vegetation was the supply of organic matter and biomass, because the hydrological regime is deficient, but especially the lithological substrate (loess) to steer solification to types characteristic of the cernisols class. Under the influence of environmental factors and pedogenetic processes within the locality Daneasa it formed a wide range of soils, namely: protisols, cernisols, luvisols, hydrisols and salsodisols.
