Megjegyzések:	Soil enzyme activities are "sensors" of soil organic matter (SOM) decomposition sincethey integrate information about microbial status and physico-chemical condition of soils. Wemeasured dehydrogenase enzyme activity in a deciduous temperate oak forest in Hungary under littermanipulation treatments. The Síkfőkút Detritus Input and Removal Treatments (DIRT) Projectincludes treatments with doubling of leaf litter and woody debris inputs as well as removal of leaflitter and trenching to prevent root inputs. We hypothesized that increased detrital inputs increaselabile carbon substrates to soils and would increase enzyme activities particularly that ofdehydrogenase, which has been used as an indicator of soil microbial activity. We also hypothesizedthat enzyme activities would decrease with detritus removal plots and decrease labile carbon inputs tosoil. After ten years of treatments, litter removal had a stronger effect on soil dehydrogenase activitythan did litter additions. These results showed that in this forest ecosystem the changed litterproduction affected soil microbial activity: reduced litter production decreased the soil dehydrogenaseactivity; increased litter production had no significant effect on the enzyme activity.
