- Abstract
- This work studies the effects of wood amendments on soil microbial community functioning
and on the potential of this community for linuron degradation. For this purpose, soil
dehydrogenase activity and the number of live bacteria, which represent broad scale
measurements of the activity and viability of soil organisms, were assessed in soil treated
with linuron and either amended with pine or oak wood or unamended (sterilized and nonsterilized).
The overall results show that the microbial community had a significant role in linuron degradation. The linuron half-life values indicated a slower degradation rate in pine and oak amended soils than in unamended ones. This is attributed both to the higher sorption of linuron by these soils compared to the unamended ones and a consequent lower bioavailability of the herbicide for microbial degradation, and to the use of the pine and oak as an alternative carbon source by degrading microorganisms. Linuron did not affect the microbial community in terms of dehydrogenase activity and number of live bacteria, presumably because it had adapted to the herbicide. However, the dehydrogenase activity was significantly higher in the soils amended with pine or oak than in the non-amended ones, indicating that the presence of a carbon source favoured the overall bacterial community.
