Some genetic peculiarities of natural and arable Grey Forest Soils (Greyzem) are presented in order to improve their classification. The textural differentiation of the typical (natural) grey forest soil profile from the northwest of the Northern Moldavian Plateau occurred under the action of three pedogenesis processes: in situ alteration of the soil material; leaching of the alteration colloidal material; migration on the profile of water-soluble organic-mineral compounds of Fe and Al in the podzolic process. The weakly textural differentiation of the arable grey soils profile is due to the partial inclusion of the illuvial horizon in the arable layer with a thickness of about 35 cm, the intensification of the in situ alteration process in the arable layer of these soils due to the change of reaction and hydrothermal regime as result of agriculture use. The textural differentiation of the grey forest soils profile in complex with other indicators is an important diagnostic index for improve the classification status of grey forest soils from forest-steppe of the Republic of Moldova.
