IMPACT OF FOREST LITTER OF ALNUS GLUTINOSA (L.) GAERTN., ALNUS INCANA (L.) MOENCH, ALNUS VIRIDIS (CHAIX) LAM. ET DC, ABIES ALBA MILL., AND FAGUS SYLVATICA L. ON CHOSEN SOIL PROPERTIES

ABSTRACT
The research covered the impact of forest litters on the content of organic carbon, nitrogen and other macroelements as well as the soil reaction. Forest litter samples were obtained from black (A. glutinosa), grey (A. incana) and green (A. viridis) alder forests as well as from beech (Fagus sylvatica) and fir (Abies alba) forest. Compared to beech and fir trees alders enrich soil with organic carbon and nitrogen much stronger. Out of the three studied alder species the green one enrich the soil most intensively.
Key words: nitrogen, forest soils, litter, alders..
