The soil protection and preservation represents the main modern agriculture task while the industry and other economic branches dispose important quantities of noxes and wastes that are stored upon the soil surface and get into it determining the disturbing of the natural processes of soil genesis and life. Within the soil, like any other ecosystem there are unfolded multiple and complex reactions from where there results complex products that are present within the plant structure and other living organisms and this is the reason why in an intensive agriculture there must be taken all measures for soil protection so it can produce nutrients and biomass. The practice has demonstrated that the soil has a fragile ecological equilibrium that can easily changed by polluting action of some internal or external factors. The achieving of the proposed theme can be considered very important being included into the prior domain of sustainable development on Romania land, of preserving the biodiversity and environment quality and minimization of global changes. The proposed researches have to respond to some clear objectives of identifying the causes and understanding the mechanisms of deterioration of the structure and quality of natural and human environment components of reducing the risk and the natural and human impact on the complex social and ecological relations from the nearby zone to the Craiova Chemical Plant and Power Plant. The researched zone stretches on a 30 km distance away of Craiova Chemical Plant and Power Plant. In order to know the soils and their features there have been made researches on field and laboratory analyses. Within the studied zone there were identified reddish preluvosoils, preluvosoils, vertosoils, sandy soils, mollic glyosoils and alluvial soils.
