| Description
| - At present, the proportion of Norway spruce stands in the Czech Republic amounts to about 54%. Natural composition should amount to 11% and recommended proportion is 36.5%. Today, research is particularly focussed on defining the properties of forest sites unsuitable for growing spruce monocultures, changes in the cycle of elements (particularly nitrogen), processes of the organic residue decomposition and relationships between the condition of nutrition, soil properties and climatic conditions. A network of demonstration areas has been established for komparative studies of forest stands in the various degree of transformation. The meaning of transformation does not generally consist in the replacement of spruce monocultures by stands of other species but in assigning such a position to spruce where a multi-purpose forest will be in accordance with the forest site capacity. In experimental plots Hetlin, the process was studied of the accumulation of organic matter in the surface humus in spruce monoc

- V České republice došlo v posledních dvou stoletích k výrazné druhové změně lesních porostů ve prospěch jehličnatých dřevin, převážně smrku. Na základě studia změn půdních vlastností byly zhodnoceny ekologické dopady smrkových monokultur i transformačních procesů pomocí buku a jedle. Na příkladu lokality Hetlín (Městské lesy města Kutné Hory) bylo poukázáno, že smrkové monokultury výrazně zpomalují koloběh živin, zejména dusíku a zvyšují aciditu svrchních půdních horizontů. Nově založené bukové porosty podmínily rychlejší dekompozici zejména vrstev L a F povrchového humusu, snížily půdní kyselost a zvýšily obsah Ca v horizontu A. Jedle se výrazně projevuje zejména rozložením kořenového systému do větší hloubky půdních substrátů. Rovněž bylo konstatováno, že zvýšená akumulace povrchového humusu se neodrazila ve výživě dospělého smrkového porostu. (cs)
