Fertilization of spruce monocultures in the territory of Training Forest Enterprise in Kostelec nad Černými lesy
- Faculty of Forestry and Environment, Czech University of Agriculture in Prague, Prague, Czech Republic
Long-term fertilization effects were evaluated including NPK, Ca and N applications at the lower altitudes. The studied localities are in the territory of Training Forest Enterprise in Kostelec nad Černými lesy, at an altitude of 300-500 m a.s.l., sites of beech-oak-fir types. Fertilizers were used in 1965-1967, the evaluation of soil condition was done in 1967 (before fertilization) and 2002. After 25-35 years, only low effects of fertilization are detectable in the humus forms and complex soil profile - surface humus accumulation, soil chemistry, as well as nutrient contents. Complex fertilization was reflected in higher site fertility in general, N-fertilization only in the progress of acidification. During the period 1967-2002, a strong general trend of acidification is obvious caused by both acid deposition and Norway spruce monoculture-based forestry.
