Проведено изучение вторичного гидроморфизма в условиях склонового рельефа Белгородской области. Установлено нарастание неоднородности почвенного покрова опытного участка в связи с развитием процесса оглеения: выщелоченные и типичные черноземы замещаются лугово-черноземными почвами. Усиление гидроморфизма приводит к появлению морфохроматических признаков в почвенном профиле. Временной тип гидроморфизма можно диагностировать по окраске почвы в целом и наличию ржавых пятен. Вторичный гидроморфизм почв сильнее выражен в нижней части склона вследствие более близкого залегания грунтовых вод.The study of secondary hydromorphism of soils in the conditions of slope relief of the Belgorod Region was conducted. The typical and leached chernozems with different degrees of washout dominated during the organization of the plot. Subsequent soil surveys showed the growing heterogeneity of the soil cover in connection with the development of the process of gley formation: chernozem is replaced by the meadow-chernozem soil. The strengthening of hydromorphism leads to the appearance of morphochromatic characteristics in the soil profile: there is a partial reduction of iron and manganese in the conditions of the temporary hydromorphism and the rusty spots formation in the soil profile; at constant hydromorphism iron is in the reduced migration-capable form, and therefore part of the profile with complete anaerobiosis acquires a greenish-blue color.Depth of temporary and permanent hydromorphism appearance varies widely due to the heterogeneity of granulometric composition of rocks on the slope of the river valley, but overall the secondary hydromorphism soil is stronger at the bottom of the 3-5° slopes because of the closer occurrence of groundwater. The rusty interlayers and greenish color are detected here within the first meter.
