Abstract:
Most agricultural land in the Republic of Moldova (about 80%) is located on slopes with different inclination. The
purpose of this paper is appreciation soil losses for ordinary chernozems with different degrees of erosion which leads
to their degradation in the reception basin “Negrea”. From the data analysis concerning soil losses washed it notes that
they are in close contact with degree of erosion. In this way in the eroded ordinary chernozem soil losses constituted:
poorly eroded - 9.3 t/ha, at the moderately eroded - 12.8 t/ha, increasing to 22.2 t/ha in the soil with strong degree of
erosion. The effect to degrading of soil erosion it is not limited only to the removal of fertile layers but also the
deterioration physical, chemical, hydric and biological its properties. The indirect impact of erosion process on
environmental components it refers to training in the cycle of mineral and organic compounds from outside the
agricultural lands. Regarding of loss of fertile soilsoils reception basin "Nergrea" accordance with data obtained, fall
within the following classes of erosion danger: absent – not eroded and typical delluvial; moderate - poorly and
moderately eroded; big - strongly eroded.
