The purpose of the study is to evaluate morphological and physical properties of the soils with different levels of erosion in the catchment basin “Negrea” (Republic of Moldova) based on the data obtained from six main soil profiles. We made a morphological description of the profiles and developed a soil map at a scale of 1:5000 showing the spatial distribution of soils with different levels of erosion. The diversity of relief forms, rocks and agricultural land use determine the existence of a variable and complex soil cover consisting mainly of common chernozems (83%). Loam, clay-loam and sandy-dusty soil texture, as well as the unsatisfactory hydrostability of the soil structure are contributory factors for erosion spreading processes on agricultural lands. The soils on slopes are affected by denudation and evolve through a denudation-compensation pedogenesis, it means that there is a certain development of the soil in depth during the relatively long period of slow denudation, thereby pedogenesis compensates, at least partially, the denudation. In the case of the anthropogenically accelerated erosion, resulting from inadequate management practices, great soil losses cannot longer be compensated by pedogenesis. |
