The aim of this study was to estimate (i) the influence of different soil types on the net input of new C into soils under CO2 enrichment and (ii) the stability and fate of these new C inputs in soils. We exposed young beech–spruce model ecosystems

Preferential flow is a common phenomenon in soils, but the temporal stability of the heterogeneous flow pattern is largely unknown. We give evidence that preferential flow paths in a structured forest soil are persistent for decades. After staining p

Natural abundance (δ) of the stable isotopes 13 C and 15 N has gained acceptance for studying C and N cycling in forests. In most studies, bulk soil samples are collected to determine isotope abundance. Such sampling overlooks the potential impact o

Summary As a consequence of heterogeneous transport in soils, only a small part of the soil might be responsible for sorbing incoming elements. After staining preferential flow paths in forested Dystric Cambisol with a colour dye, we sampled soil mat

To evaluate and parametrize transport models for the vadose (partially water-unsaturated) zone, information about the spatial distributions of solutes is needed. We describe a technique for the simultaneous imaging of several fluorescent tracers in s

Migration of radionuclides in soils and their transfer to edible plants are usually estimated using volume-averaged bulk concentrations. However, radionuclides might not be homogeneously distributed in soils due to heterogeneous water flow and solute

The objective of this study was to provide a contribution to a database on the heavy metal status of tropical soils. We assessed the partitioning of Al, Cd, Cu, Fe, Mn, Pb, and Zn in A horizons of Costa Rican soils used for coffee cultivation. These

The northwestern province of Costa Rica is a marginal coffee growing area. At the onset of the rainy season low redox potentials probably induce the mobilization of soil Mn resulting in enhanced plant uptake of Mn. To test this hypothesis we monitore
