Study of thickness of humus profiles of gray forest and chernozem soils of different terms of agricultural use in landscape shrubs of the central forest-steppe

The article presents the results of a field study thickness humus profiles gray forest soils and podzolized chernozems dif-ferent terms agricultural use soil catens broad-leaved-forest (background) meadow-steppe areas Belgorod region. work was carried out in spring summer period 2018-2019. objects were different-aged arable plots with age development 100 160 years, respectively. steepness surface on did not exceed 5-60. It is established that profile under influence cultivation during 60 years has decreased by 49 cm, at slopes northern exposition this index more expressed (33 cm) than southern (16 cm). possible, to note, increase expositions greatest horizon observed anomalous (72 65 sm accordingly). Within background cover homogeneous, second each studied transects.
