Abstract

Given the evolution of the climatic conditions in the last 10 years, especially in terms of reducing rainfall and increasing average annual temperatures, especially in the southern half of Romania, soil profiles and studies have been carried out in different areas of the south of the country including Dobrogea, with different pedoclimatic conditions. For this purpose, soil profiles and surveys were carried out in two counties in the south of the country, respectively: Dolj and Constanta, from which soil samples were taken both in natural and modified settlement. Soil samples were conditioned (drying, mortar and sieving) in USAMV laboratories in Bucharest and analyzed in INCDPA laboratories in Bucharest.
In all analyzed samples, a reduction in humus content was found due to rapid mineralization against the background of reduced precipitation and excessive heating. As for the reaction of the soil, due to the applied technology, in particular, fertilizing with chemical fertilizers with a physiological acid reaction, led to a decrease in the value of the reaction by one unit.
