The aim of the research was to identify the main agriproductive properties of the typical reddish preluvosol in the area between Jiu and Olt rivers and to follow its evolution over a period of 20 years, in order to obtain relevant results. This area was chosen as studies had been made since 1993, when rigorous research began to develop into a doctoral thesis. Having well documented and interpreted baseline data, we considered it appropriate to come up with new research in the respective area after a sufficiently long period of time, to identify relevant changes at the level of the main agriproducts of this type of soil. Based on the results of the analyses and their interpretation, we found that at this level of soil there were no substantial changes during this period, considered short in regard to the genesis and the evolution of a type of soil. Moreover, due to the presence of farms and agritouristic households in this perimeter, we considered it wise to carry out research into the presence and concentration of the more common heavy metals. From the main research results we found that several heavy metals such as chromium (Cr), copper (Cu), nickel (Ni), zinc (Zn), cadmium (Cd), lead (Pb) are indeed present, but their concentration does not exceed the normal limits, except for chromium, which slightly exceeds this limit, but still is far below the alert threshold. The results highlight that agricultural producers can obtain high quality agrifood products, that do not pose any safety and traceability risks, and that can be offered to potential tourists without any concerns.
