Abstract—The soil formation was studied in the 21- to 35-year-old pine plantations created on the overburden
dumps of the Nazarovskaya Depression without applying the material of the humus horizon. The surface tech-
nogenic formations under the pine plantations belong to the group of naturfabricats (surface formations devoid
of the humus horizon and composed of natural substrate). The morphological characteristics, bulk chemical and
particle-size compositions, and labile properties of the soils indicate that the accumulation and transformation
of organic matter are dominant processes in the artificially planted forests. The accumulation of organic resi-
dues and destruction and humification are tightly related to the environmental conditions transformed by the
technogenesis and conceal other processes forming the soil profiles. Quasizems created for agricultural produc-
tion purposes were the objects of the study. They were formed by covering the technically planned overburden
rocks with the material of humus layers. The thickness of the humus horizons of the quasizems varies greatly
(25–64%); the variation of the humus reserves in them is 34–122%. Middle-profile horizons have not been
formed by the present time.
