vegetation - Opis:
- Considering plant-to-soil pathways, decomposition of vegetative fluxes such as litter and litterfall is one of the important processes that adjust the carbon cycle and nutritional elements in the formation of a forest's organogenic horizon. However, there is little information available on this subject, and the fractional structure (amount, type and interrelation) of organic matter also seems to receive little attention. Using 7 different vegetative samples, a field study was performed over 3 years to find the relation between phenolics content and mass losses in the subarctic region (N66° and E31°). In addition, climate effects on this relation were investigated. The data obtained from this field study testify that (i) an intensive loss of organic matter occurred in active parts of various litterfalls and (ii) leached phenols were related with mass losses (decomposition rates) of vegetative fluxes (litterfalls and litters) to the soil. The statistic analysis suggests that (iii) total mass losses of samples (except litter) were connected with both the temperature sum and the precipitation sum, and (iv) phenolics losses also had a similar trend in different kinds of litterfall.
