Soil is a limited means of production in space that cannot be multiplied as other means of production. The purpose of our research is to highlight the various aggregate particles of the ordinary chernozems in Negrea village, subject to the erosion process. Thus, we can appreciate the suitability of soils for different uses and recommend measures to mitigate the negative consequences. It is necessary to emphasize that any eroded soil is a result of a balance between the permanent process of pedogenesis and the process of its physical deterioration through erosion (Canarache, 1990; Cerbari, 2010; Kacinskii, 1958). The diversity of the natural conditions of solification and their interaction with the anthropic factors led to the formation on the researched territory of a soil with variable and complex character. A particular feature of the soil cover is the absolute predominance of ordinary chernozems in its structure (Kuznetova, 1979). The complexity of the soil cover structure, the diversity of the destructive influence of natural factors (Jigău et al., 2002; Jigău, 2008) the intensity of anthropogenic activity determined the widespread manifestation of land degradation processes in agricultural fields. According to dry curing data, the studied soils are characterized by favorable, predominantly satisfactory agronomic structure, and reduced hidrostability. Exceptions are made only by not eroded ordinary chernozems and mollic delluvial soil. Their structure, according to dry data, is appreciated as good and the hydrostability of their structure, according to wet milling data, is classified as satisfactory. The characteristic of the not eroded ordinary chernozem is the possibility of accumulation of comparatively large amounts of precipitation water as a positive factor contributing to the reduction of the soil erosion hazard (Cojocaru, 2016).
