Currently, the land fund of the Republic of Moldova is intensively utilized, which has led to the drastic reduction of the areas covered by natural vegetation, and, respectively, to the change in the direction of the evolution of pedogenetic processes in the soils. It is known that the formation of gray soils took place under deciduous forests. The forests of the Republic of Moldova are also in an alarming state. Compared to other countries, the Republic of Moldova shows very low indices specific to forest resources. At the same time, forests are important renewable and strategic natural resources that influence and improve the quality of the surrounding environment. Forests play an important role in combating desertification, mitigating climate change, soil degradation processes, etc. Different forms of degradation affect the gray soils from the Cubolta hydrographic basin, introduced into the agricultural circuit: dehumification, destructuring, erosion, compactation, etc. Following the research carried out by the working group of the Laboratory of Geomorphology and Ecopedology of the Institute of Ecology and Geography, it was established that the gray soils following deforestation and their passage into the agricultural circuit lost about 30-40% of humus.
