T1 - A Model Approach Assessing The Soil Properties Of Raised Bed Landscapes T2 - EGU General Assembly 2022, Vienna, Austria, 23–27 May 2022 N2 - Common anthropogenic surface features across Scotland and Ireland are raised beds, which are agronomic ridges and furrows created prior to the 20th century to improve agricultural yield. Creating a raised bed improves yield by providing to the root zone better soil drainage, suitable micro-climatic conditions, and enrichment of organic matter and nutrients. Raised beds are structurally identifiable and can be examined using remote sensing techniques such as LIDAR imagery or aerial photography to analyze different dimensions of raised bed units. We examined the geomorphic parameters (height, length, breadth, ridge shape, furrow depth, unit orientation and block size) of raised beds found in the Fancroft region of County Offlay, Ireland. We developed a model of raised bed structural components and the distribution and change in soil properties including soil drainage, texture, horizon differentiation, soil colour, nutrient distribution, organic matter movement and the carbon influx and outflow have been provided. Our study aims to elucidate the typical geomorphic properties of raised bed landscapes, their basic chemical and physical soil properties and the landform attributes that may influence soil properties. Overall, the conceptual basis of raised bed landscapes have been visualised and presented to formulate an ideal raised bed theoretical model. Such a comprehensive model can be further extended to learn more about ancient agricultural practices, heritage, a causal link between present day and historical farming practices.

A1 - Raab, Alexandra A1 - Schneider, Anna A1 - Bonhage, Alexander T1 - A novel view in geopedology : how small landforms from past land use affect the pedosphere T2 - Centennial Celebration and Congress of the International Union of Soil Sciences N2 - LiDAR-based high-resolution digital elevation models (DEMs) can now provide a centimetre-accurate image of the Earth's surface. Soil science is still in the early stages of realising how fundamentally this new technology will change our understanding of the formation, properties and functions of the pedosphere and in particular the uppermost part of it, which usually represents A horizons. With the help of high-resolution DEMs, it is possible to identify and classify small topographic features that were previously not considered in soil mapping. Therefore, precise landform analyses will be crucial in assessing variations in soil horizonation and soil stratigraphy and will provide the framework for a new perspective in Geopedology that truly integrates Geomorphology and Pedology from pedon to soil landscapes. In the digital domain, this geopedological approach is growing rapidly by using artificial intelligence (AI) to automatically identify small landforms and visualise the heterogeneity of diverse pedological information. We present the results of the study of different types of relict anthropogenic landforms (RALs) and highlight their characteristics and differences compared to natural, undisturbed soils. The origins of these relict features can vary greatly, as can their distribution, morphology and age. The analysis of high-resolution relief models in Europe and the USA shows that morphological features can be found, particularly in forest that were created in pre-industrial times. Settlement structures (e.g. stone walls, burial sites) or linear relief forms created by soil cultivation (e.g. field terraces, furrow systems) are common. Relict Charcoal Hearths (RCHs), which originate from historic charcoal burning, are usually small circular platforms surrounded by pits or ditches, but can still cover a considerable part of the area. A relatively complex geomorphology can be observed in historic mining areas, which may include different landform types such as mine shafts and spoil heaps, resulting in a very heterogeneous pedological mosaic. To summarise, all studies reveal a high variation of soil properties controlled by small relief structures. Pedology should take this more into account in the future and improve knowledge of the impact of RALs on the pedosphere and other components of ecosystems.
