The genesis of contemporary soils, formed under the vegetation of deciduous forests, grey and brown soils, as well as their evolution over time as a result of long-lasting climatic oscillations and anthropogenic impact, are treated differently; some of their peculiarities in different climatic subzones of the Republic of Moldova are not always taken into account when developing their classification. Taking into account the recommendations of the World Reference Base of Soils to name high-ranking soil taxonomic units (at the type level) in one word, in the proposed classification system, forest soils have now been renamed as: xeroforestry chernozems, greyzems, brownzems. Moldova is located at the intersection of three biogeographical areas whose natural conditions have a decisive impact on the evolution of all components of the environment, including soils. The anthropic use of forest soils in arable lands causes unprecedented changes in landscapes, ecosystems and environment, and the current climatic situation corresponds to the formation of chernozems throughout Moldova.
