CO2 fluxes from soil, together with soil water content and temperature have been measured over one solar year in an even-aged beech forest (Fagus Sylvatica L.) in southern Italy.

The influence of soil temperature and soil moisture on soil respiration was also analysed.

There were no significant differences in soil temperature between the treatments, whereas soil water content was statistically different only in the innovative treatment. The study showed that the mean soil respiration increased with thinning intensity, confirming that after harvesting, residues remaining on the forest floor and decomposing roots may contribute to raise soil respiration, due to the higher microbial activity.

Abstract
CO2 fluxes from soil, together with soil water content and temperature have been measured over one solar year in an even-aged beech forest (Fagus Sylvatica L.) in southern Italy. We investigated the effects of three different harvested biomass removal treatments (traditional, innovative, unharvested control) on soil respiration (Rs) in three plots from May 2014 to April 2015, with the aim to evaluate the effects of such silvicultural practices on the CO2 respired from the forest floor. The influence of soil temperature and soil moisture on soil respiration was also analysed. Rs showed large variations among the treatments, with the innovative treatment resulting in significantly higher soil respiration than control and traditional treatments. There were no significant differences in soil temperature between the treatments, whereas soil water content was statistically different only in the innovative treatment. The study showed that the mean soil respiration increased with thinning intensity, confirming that after harvesting, residues remaining on the forest floor and decomposing roots may contribute to raise soil respiration, due to the higher microbial activity.File | Dimensione | Formato | |
