August 2019 N2 - Die Beimengung von Holzkohle in Böden kann deutlichen Einfluss auf die physikalischen Bodeneigenschaften haben. Solche Effekte treten nicht nur in gezielt mit Holzkohle („biochar“) angereicherten Ackerböden auf, sondern auch auf den Standorten historischer Holzkohlemeiler (HKM), die in vielen Waldgebieten in großer Zahl vorkommen. Die prägendste Eigenschaft solcher Böden auf HKM ist eine technogene, kohlereiche Substratschicht, die über dem natürlich entwickelten Bodenprofil abgelagert ist. In jüngster Zeitwurden in mehreren Studien ein von den umliegenden Waldböden abweichendes Vegetationswachstum und eine abweichende C-Dynamik auf HKM festgestellt. Welche Bodeneigenschaften der HKM solche Unterschiede bewirken, ist aber noch unklar. Ein möglicher, bisher kaum untersuchter Einflussfaktor ist die Bodentemperatur. Ziel dieser Studie war es, den Einfluss von Holzkohlebeimengungen auf die Wärmeleitfähigkeit und das Bodentemperaturregime von HKM-Böden zu charakterisieren. Untersucht wurden HKM auf sandigem Substrat in der Lausitz (Brandenburg). An zwei Standorten wurden Profile auf HKM und benachbarten Waldböden für ein Monitoring der Bodentemperatur über jeweils ein Jahr instrumentiert, die Wärmeleitfähigkeit von HKM-Schicht, Ah-, fAh-und Bv-Horizont wurde im Labor bestimmt. In einem Laborexperiment wurde zusätzlich die Wärmeleitfähigkeit von künstlich hergestellten Proben aus sandigem Substrat und Holzkohlefragmenten in unterschiedlichen Mischungsverhältnissen untersucht. Die Ergebnisse zeigen eine deutlich verringerte Wärmeleitfähigkeit des kohlereichen Substrats. Damit verbunden zeigen sich im Monitoring geringere Schwankungen der Bodentemperatur auf den HKM in tiefen Bereichen des Profils, in den obersten Dezimetern wurden hingegen stärkere Schwankungen der Bodentemperatur festgestellt. Insgesamt zeigt sich damit ein noch über die technogene Substratschicht hinaus wirksamer Einfluss der typischen Eigenschaften des kohlereichen HKM-Substrats auf die Bodentemperatur.

August 2019 N2 - Recentfindings of more than 4000 relict charcoal hearths (RCH) in the forest district Tauer (Brandenburg, Germany) raise the question to what extent soil properties are controlled by a legacy effect of historical charcoal burning. RCH sites are characterized bya substantial admixture of charcoal fragments of varying particle sizes constituting an anthropogenic addition of carbon to the natural forest soil. Ages of about 250 years proven by dendrochronological dating of larger charcoal pieces on RCHs allow for assessing long-term effects of biochar application on forest soils. In this study, we measured the geometry and SOM content of 20 RCH sites in a selected part of the forest district. The results are the basis for a projection of RCH SOM stocks on a 40 ha forest plot with 120 RCH sites. In the range of statistical uncertainties it is shown that RCHs add between 13 % and 32 % of SOM to the SOM stock of the natural forest soil in the studied plot. These substantial amounts of SOM are so far not recognized by any soil survey or forest soil inventories of SOM and SOC stocks. In light of an increasing amount of studies that detect RCH sites in forests of Europe and the USA in the range of tens-and even hundreds of thousands, the question has to be asked how to address this legacy effect in ongoing scientific discussions about soil carbon stocks, carbon sequestration and the long-term effects of biochar application into soils.

Multiple reshaping since the Late Glacial considerably changed the landscape up to and including especially historic times. Sediment sequences and (fossilized) soils can improve our understanding of Late Quaternary landscape development, but mapping of buried soils and surfaces is often limited to single outcrops. Ongoing archaeological rescue excavations in the pre-field of the open-cast mine Cottbus-Nord (northeastern Germany) with dense excavation trenches in an about 10 ha dune and drift sand area reveal multilayered sediment sequences with fossilized soils and sediments from the Late Pleistocene to the Late Holocene. Archaeological findings ranging from Mesolithic flint stones to an about 200 year old ceramics in eolian sediments covering plow horizons and wheel tracks suggest that eolian relocation of sandy material was intensive about 200 years ago. Still unpublished OSL dating underline the intense eolian activity. Recent studies showed that between the 15Th to the 19Th century an iron smelter 5 km to the west of our study site was supplied with charcoal, which was produced in a forest 5 km east to our study site. Our current findings about Late Holocene eolian activity raise the question if this eolian reshaping of the landscape is connected with the operation of the iron smelter either directly by transport or bog iron ore winning or indirectly by population pressure caused by the prospering iron smelter. Our ongoing research indicates, that already for historic land-use off-site effects causing further landscape changes have to be considered.

Since many decades lignite opencast mines have been operating in this region which is known as the Lusatian mining district. The total land demand in Lusatia is about 852 square kilometres and mining will continue for many more years or even decades. Large-scale outcrops resulting from these mining activities are excellent archives to study the younger Earth’s history. The scope of our research in open cast mines is to reconstruct the Late Quaternary landscape development and to distinguishing natural from anthropogenic forcing and processes. In more detail, the aims are to identify and to quantify the impact of past land uses, i.e. changes of vegetation, landforms and soils induced by agriculture and/or forestry. Here, we are presenting latest results from our research and review important findings giving novel insights into man-induced environmental changes in Lusatia within the past thousands years and thus improving the general understanding of Late Quaternary landscape dynamics.

The increasing availability of high-resolution ALS data has given rise to many recent studies mapping such land use legacy features, which have revealed impressively high numbers and spatial densities of RCHs in many regions of the world. Nevertheless, the limitations of mapping from remotely-sensed data still need to be considered to allow for meaningful interpretations of RCH spatial distribution patterns and conclusions on past forest use. We present an assessment of the possibilities and limitations of RCH mapping from ALS data on the landscape scale, comparing mapping results from study areas in the Northeastern German Lowlands, the German lower mountain ranges and the lower mountain ranges in the northeastern USA. RCHs were mapped using automated detection and manual digitization, and mapping results were validated against archaeological excavations and detailed field surveys. The results allow for a detailed analysis of mapping accuracy in relation to DEM resolution and feature size, but furthermore show up relations of mapping success to RCH age and preservation and to geomorphology and subsequent forest use. Results CAA 2019 279 Standard session 42: New technologies in woodland archaeology: problems and limitations from a GIS analysis of RCH spatial distribution in relation to historic charcoal-consuming industries affirm that RCHs are a widespread and underestimated legacy of past woodland use in many regions, but also underline the relevance of considering variable mapping accuracy in landscape-scale analyses of archaeological relief features mapped from ALS data.

However, whether there is synchronisation of these strategies at the entire community level is unclear. Here, we combine trait data for 2800 above- and belowground taxa from 14 trophic guilds spanning a disturbance and resource availability gradient in German grasslands. The results indicate that most guilds consistently respond to these drivers through both direct and trophically mediated effects, resulting in a ‘slow-fast’ axis at the level of the entire community. Using 15 indicators of carbon and nutrient fluxes, biomass production and decomposition, we also show that fast trait communities are associated with faster rates of ecosystem functioning. These findings demonstrate that ‘slow’ and ‘fast’ strategies can be manifested at the level of whole communities, opening new avenues of ecosystem-level functional classification.

Open questions about RIFU formation and potential legacy effects still exist, especially related to physical soil properties. Aims Our aims were (1) to characterize the soil properties of RIFU soils and (2) to compare the drought sensitivity and the growth resistance in extremely dry years of trees growing on ridges and furrows, respectively. Methods We studied soil physical (bulk density, saturated soil hydraulic conductivity, and texture) and chemical (soil pH, soil organic matter, and nitrogen content) properties and the climate sensitivity of tree growth on RIFU systems for three study sites in Prignitz, Germany. Results RIFU systems showed a high spatial heterogeneity of soil stratigraphy due to ridge construction and increased accumulation of soil moisture and organic matter in furrows due to post-abandonment pedogenesis. Slight spatial differences in soil physical properties were found, with increased air capacity in ridge soils and higher available water contents in furrow soils. No differences in drought sensitivity were observed for trees growing on ridges and furrows, except for a wet site, where trees in furrows showed a higher sensitivity. Resistance in dry years tended to be similar or increase from furrows to ridges. Conclusions The results reflect a spatial differentiation of stratigraphy and post-abandonment pedogenesis on abandoned RIFU systems and suggest an adaption to different moisture conditions through RIFU construction. Differences in drought sensitivity of tree growth with relative land surface could only be detected for one of the three sites, where trees were found to be less drought sensitive on ridges.
