This article presents the properties of typical serozem soils. In Uzbekistan, along with serozem (gray) soils formed in loess deposits, reddish serozem soils formed in Neogene deposits are also widespread, which are distributed in mountainous and foothill areas. Reddish soils differ from serozem soils formed in loess deposits by their appearance, genesis, and properties. The reddish- serozem soils formed in the Neogene deposits are widespread in many parts of Uzbekistan and are subject to various levels of erosion. The reddish-brown soils formed in the Neogene deposits are mainly formed in the parent rocks that form a homogeneous loess soil, in some places these layers are very shallow and in the strata occur tertiary and calcareous loams, sands and conglomerates.
