Accumulation of the surface humus and soil chemistry in forest soils were compared with agricultural lands afforested 60 years ago. The research was done in the vicinity of the Sachotin village, Czech-Moravian Highland. The forest soil state was compared with the arable soil in the same site. Different types of forest stands were evaluated (old or new Norway spruce trees, Norway spruce + birch trees). The highest surface humus amount was documented in the old Norway spruce stand (62.8 t/ha), a lower one was found in the spruce + birch stand (52.0 t/ha), the lowest one in the afforested agricultural soil (45.9 t/ha). The arable soil showed very unfavorable soil chemistry, whereas the different forest soils studied did not show any significant differences. The effect of birch can be considered as favorable.
