Abstract Acid deposition arising from sulphur (S) and nitrogen (N) emissions fossil fuel combustion agriculture has contributed to the acidification of terrestrial ecosystems in many regions globally. However, Europe North America, S greatly decreased recent decades due controls. In this study, we assessed response soil solution chemistry mineral horizons European forests these changes. Trends pH , acid neutralizing capacity ( ANC ), major ions, total aluminium (Al tot ) dissolved organic...
Abstract Understanding the processes that underlie drought‐related tree vitality loss is essential for anticipating future forest dynamics, and developing management plans aiming at increasing resilience of forests to climate change. Forest has been continuously monitored in Europe since acid rain alert 1980s, intensive monitoring plots ICP Forests offer opportunity investigate effects air pollution change on condition. By making use over 100 long‐term plots, where crown defoliation assessed...
Fagus sylvatica L. is one of the most widespread tree species in temperate forests Western Europe which plays an important role both ecological and economic terms. European beech stands were especially adapted to past climate but have suffered a decline last recent years. Climate change increased frequency extreme events (droughts, heatwaves also rainfall) seem be impacting their vitality even if exact description this phenomenon still unclear.In context, we monitored around 97 plots...
Abstract The stabilizing properties of mineral–organic carbon (OC) interactions have been studied in many soil environments (temperate soils, podzol lateritic and paddy soils). Recently, interest their role permafrost regions is increasing as was identified a hotspot change. In thawing ice‐rich regions, such the Yedoma domain, 327–466 Gt frozen OC buried deep sediments. Interactions between minerals are important because located very near mineral matrix. Mineral surfaces elements could...
Lignin concentration in organic residues largely controls their decomposition. Mn 2+ may well play a key role ligninolysis because it is cofactor of manganese peroxidase, an enzyme the lignin-degrading system. This study aims to investigate effects addition on forest floor horizon decomposition during laboratory incubation. Therefore, we sampled two distinct floors from European beech ( Fagus sylvatica L.) stands: mor and moder. concentrations upper layer were significantly larger moder than...
Summary Surface podzolization has so far been diagnosed from morphological observations, selective extraction and mineralogical investigations. We studied this process in two Cambisol profiles developed loess, one with a fibrimor humus the other dysmoder humus, by characterizing chemical composition complexing properties of soil solution. The solutions were sampled bimonthly for 3 years at four depths (4, 8, 13, 25 cm) using both zero‐tension low‐tension capillary‐wick lysimeters. leachates...
Abstract. Climate change affects forest growth in numerous and sometimes opposite ways, the resulting trend is often difficult to predict for a given site. Integrating structuring knowledge gained from monitoring experimental studies into process-based models an interesting approach response of ecosystems climate change. While first generation operates at stand level, one now needs spatially explicit individual-based approaches order account individual variability, local environment...
Summary Surface podzolization involves the migration of metal–humus complexes to a depth few centimetres. In acid soils derived from loess, this process has been diagnosed mainly by morphological observation. We investigated in toposequence Luvisols and Cambisols on loess using selective extraction mineralogical data as well characteristics leaf litter. The humus type (O OAh horizons) is moder three one Cambisols, whereas it fibrimor two other Cambisols. contents total alkaline...
