TL;DR: In this paper, preferential flow paths have higher microbial biomass and different microbial community structures than the rest of the soil, and the organic C concentrations in the preferential flow path were 10 to 70% higher than in the matrix.

TL;DR: In this article, the authors present an overview of trace element concentrations in Swiss forest soils and to critically assess the measured values with respect to anthropogenic input vs. lithogenic background.

TL;DR: The approach used here to calculate cumulative, anthropogenic, atmospheric Pb (CAAPb) is simple and robust, independent of the chronology of Pb deposition, and makes no assumptions about the immobility of P b within the peat profile.

TL;DR: In this paper, a 4-year experiment where spruce and beech, growing on an acidic loam and on a calcareous sand, were exposed to increased CO 2 that was depleted in 13 C. The results suggest that dissolved organic C is produced during incomplete decomposition of recalcitrant native C in the soils, whereas easily degradable new components are rapidly consumed by microbes and thus make only a minor contribution to the dissolved C fraction.

TL;DR: In this article, the spatial distribution of radionuclides in the soil in relation to preferential flow paths and the possible consequences for their transfer from soil to plants were investigated. But, the authors did not consider the effect of preferential flow on the transfer process.
