The studied area is located the north-eastern part of Călărași County, belonging to the cadastral territory Perișoru, currently used as arable. The pedological mapping was carried out with the purpose of identifying the zonal soil, by assessing its fertility as well as the influence of applied technologies on the physico-chemical properties of the soil. A soil profile and several surveys were opened from which soil samples were collected in natural and modified settlement, for morphological, physical and chemical analysis. The soil type identified is represented by typical chernozem, vermic with undifferentiated loamy texture on the profile. The main physical characteristics (bulk density, total porosity and compaction degree), chemical (soil reaction, humus content, nitrogen, phosphorus, potassium) and hydrophysical indices were determined by indirect methods. Applying high-performance culture technologies, they highlighted the improvement of the aforementioned characteristics, by creating a favorable aerohydric regime and implicitly important production increases.
