Nitrogen availability in Norway spruce forest floor - the effect of forest defoliation induced by bark beetle infestation

Original language description

The objective was to evaluate whether lower nitrogen (N) immobilization by spruce trees (Picea abies) or higher microbial N mineralization in the soil is the main mechanism changing the soil N balance after forest defoliation caused by bark beetle. We measured in situ mineral N availability using ion exchangers, net N mineralization (N-miner, ammonification and nitrification) and N content in microbial biomass (N-microb) in the forest floor of infested and control plots in an unmanaged area of The Bohemian Forest National Park. In situ N availability already increased before the defoliation culminated, which affirms the primary effect of reduced N immobilization by vegetation. N mineralization was enhanced after maximum forest defoliation (2 vs. 30 mug N g(-1) d(-1)). The contribution of N-miner to in situ N availability was supported by the correlations found between in situ mineral N availability and N-miner/N-microb and N-miner/C-miner ratios. The influence of litter input with low
