"Presentation documents the surface humus accumulation process, the dynamics of forest soil restoration and the effect of different forest stand density on the soil revitalization. The plantation of Norway spruce was established 1965 on the former agricultural land, the thinning experiment following IURFO methods was established 1971. The accumulation of surface humus and basic soil chemistry characteristics development are described in the period 1993 \u2013 2002. The control variants are compared with the heavy thinning effects. Surface humus accumulation of 35.52 t/ha (1993) and 48.56 t/ha (2002) was documented on the control variant, for the variants with lower density it varied in the ranges 24.00 \u2013 25.68 (1993) and 42.66 \u2013 35.43 t/ha. The forest stand established on the agricultural land accumulates considerable amounts of surface matter (carbon) in holorganic horizons in a relatively very short time. The soils show visible acidification in the period 1993 \u2013 2002, accelerated in the more dense" . "7"^^ . . "4" . . . . . . .
