Abstract:
The soil cover is the national wealth, natural resource and the principal means of production in the Republic
of Moldova agriculture. Purpose and research tasks consists in setting up the changes we made erosion on the chemical
characteristics of the ordinary chernozems. Were conducted the necessary investigations on the territory of the
reception basin ”Negrea”. In this paper is argument humus content, carbonates, pH, nitrogen, phosphorus, potassium
and distributing them on the soil profile. From the data obtained on changing the chemical characteristics of soils
investigated, it is noted that appears significant quantitative and qualitative differentiation of these, depending on the
degree of erosion. This means that to be able to obtain adequate productions on eroded soils, it is necessary
amelioration works to straighten primarily to improve soil properties and then to the other.
