Abstract
The research addresses an original and complex topic concerning the evolution of the main chemical properties of the chromic luvisols in the southwestern part of Romania, in Dolj County, exploited under the specific cultivation conditions of agritourist farms. The novelty of this research consists in the multidisciplinary interpretation of the analyses on chemical properties and their influence on the quality and quantity of agricultural productions. In the second part, the main chemical properties of the chromic luvisols were analysed, both for the soil developed under woody vegetation, and both for the cultivated soils. Comparing the results of the analyses, we found that the natural fertility of the cultivated soil decreased considerably, which led to a significant deterioration of the main chemical properties, precisely due to cultivation. In the third part, a study was carried out on the presence and concentration of heavy metals in this type of soil, finding from the interpretation of the analyses that the values of all the studied elements fall below the alert threshold. he recommendation on the researched aspects is that in order to limit the degradation and even improve the main chemical properties of chromic luvisols, in the agritourism farms, an ecological agriculture must be practiced.
