revitalization - Opis:
- The article assesses the influence of method of revitalisation of the forest fire site in Potrzebowice Forest District (western Poland) on basic parameters of the microbial activity in soils. We investigated study plots established in 1994, two years after the forest had burnt down completely. We applied three different methods of soil preparation and planted either Scots pines (Pinus sylvestris L.) or grey alders (Alnus incana (L.) Moench.). For comparisons an area of natural succession and untreated control plot, which was located beyond the range of the fire, were taken. 18 years after the appli−cation of the methods of renewal of the fire site, the soils have not undergone full microbiological regeneration. The soils at the fire site were mainly colonised by heterotrophic eubacteria. The population of these microorganisms, which were usually found in fresh litter and in the strict rhizosphere, was greater than in the soil of the control plot. On the other hand, there were low populations of actinobacteria, which regenerated poorly, especially at the accumulation and humus levels of the post−fire soils. The population of fungi was also lower than in the control soil. The applied methods of the fire site renewal have not had significant influence on the microbiological state of the soils under investigation. However, the rate of regeneration of the microbiocenosis after the fire in the forest soils was much faster in the case of artificial renewal than in natural succession.
