Paper documents the effects of grand fir (Abies grandis /Dougl. ex D.Don/ Lindl) on the basic characteristics of the soil chemistry and nutrient dynamics. The amount of the surface humus and basic chemical characteristics of the horizons F+H, Ah, Bv (soil pH, soil adsorption complex characteristics, total carbon and nitrogen content, C/N ratio, exchangeable acidity characteristics, plant available and total nutrient contents) were compared at two localities in young stands (38 years) of grand fir, Norway spruce and European beech on the territory of the Central Bohemia (altitude 340 and 435 m a. s. l., mean annual precipitation 660 mm, mean annual temperature 8°C, fresh to waterlogged oak-beech and beech sites). Results documented relatively slight differences among stands as a result of different species cultivation. This was determined by the site conditions and young age of particular stands. However, some positive effects of the grand fir were visible and relevant, especially higher soil reaction and soil adsorption complex characteristics. Forestry research should bring this species into focus more frequently.
