The advent of sedentism led to the expansion of agricultural areas, unintentionally causing widespread soil erosion, forming colluvial deposits. These often multi-layered colluvial deposits, which particularly occur along slopes and depressions, serve as crucial geoarchives of human-environment interactions. Using a simplified erosion–deposition model of the formation of multi-layered colluvial deposits without considering pre-burial postdepositional processes in each colluvial layer can lead to incorrect interpretations or, at best, to an underestimation of the high value of colluvium as geoarchive. Therefore, this study discusses different scenarios of possible pre-burial postdepositional changes in soil properties of individual colluvial layers, with and without human influence, and how these changes may affect the interpretation of dating results. After the deposition of a colluvial layer, influences such as ongoing agricultural activities can homogenise the respective layer, so that it is an analytical challenge to distinguish between originally successive erosion/deposition events and ultimately to establish a robust model age for the time of their deposition. By integrating high-resolution archaeopedological analyses, we explore how agricultural activities and pedogenic processes alter post-depositional soil properties, complicating the distinction between successive deposition events. The findings highlight the importance of considering non-linear correlations and post-depositional changes to establish accurate models of land-use history and erosion/deposition events.</div></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":"254 ","pages":"Article 108963"},"PeriodicalIF":5.4,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143680012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These mounds accumulate significant stores of soil organic and inorganic carbon (C), including pedogenic calcium carbonate, which may form through microbially induced calcite precipitation. In this study, the effects of land use change on C dynamics in <em>heuweltjie</em> soils were assessed by examining soil biogeochemistry and apparent respiratory quotient (ARQ, based on soil pore gas composition). We investigated the oxalate-carbonate pathway (OCP) as a potential mechanism of C sequestration. Topsoils were collected from one pristine and one cultivated termite mound in a semi-arid region of South Africa and incubated for one week. The carbon dioxide (CO₂) and oxygen concentrations of soil pore gas as well as chemical properties of soils treated with termite frass (excrement) or calcium oxalate (CaOx) were monitored. Increases in pH and the calcite saturation index in both CaOx- and frass-treated soils suggested the potential occurrence of the OCP. The ARQ values did not reflect geochemical changes associated with OCP due to competing metabolic pathways, such as potential lignin degradation in frass-treated soils. Higher ARQ values in uncultivated versus cultivated CaOx-treated soils may indicate higher carbon use efficiency in uncultivated soils or destabilization of existing C in cultivated soils. Respiration in frass-treated soils was higher than control and CaOx-treated soils and resulted in production of bicarbonate (via dissociation of carbonic acid formed by dissolution of respired CO₂ in water). This implies that termite-affected landscapes may sequester C in inorganic form. Increased total C in both cultivated and uncultivated soils treated with frass suggests that microbial CO₂-fixation may occur in termite-affected landscapes, necessitating further investigation of pathways responsible for this process.</div></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":"254 ","pages":"Article 108947"},"PeriodicalIF":5.4,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143680011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Like other historical sciences such as geology and paleontology, paleopedology works with incomplete datasets and preservation biases. Despite these challenges, paleosols provide valuable paleoenvironmental, paleobiological, and paleoecological data, allowing for inferences about past events and entities. The aim of this paper is to engage in a reflective exercise on the role played by the soil memory concept as an epistemic tool to overcome contingency, underdetermination, and equifinality—common phenomena within historical sciences—in interpretation of paleosols. The soil memory concept is related to the capacity of soil record information about soil forming factors and pedogenic processes in their characteristics. This work discusses how soil memory serves as a conceptual and methodological framework that facilitates the establishment of analogical reasoning in paleopedology. Soil memory in paleopedology identifies regularities between paleosols and soils, linking different pedogenic characteristics and processes across various spatial and temporal scales, thereby allowing paleoenvironmental explanation. Soil memory provides an ’experimental context’ to emphasize the observed regularities between different objects, such as Precambrian and Quaternary paleosols at different scales. Soil memory is not a definitive explanation but rather an open, dynamic, and exploratory tool that helps guide subsequent research steps and refine questions based on weak and in some cases unrelated evidence. Recent years have seen increased interest in the capacity of historical sciences, particularly geology and paleontology, to provide comprehensive explanations for complex events from the deep past. Integrating paleopedology into this discussion enhances our understanding of how scientific knowledge about past environments is constructed, and how the historical sciences contribute to scientific explanations.</div></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":"254 ","pages":"Article 108945"},"PeriodicalIF":5.4,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143680010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study integrates field geomorphological, geophysical, and sedimentological data, along with Schmidt-hammer relative age dating, to provide a detailed account of the development and relative chronology of ancient RSFs in this area. The northern slope of Babia Góra exhibits all major types of RSFs, including rock slope deformations, rock slides and rock avalanches, with a total volume of approximately 418 M m³. The inventory encompasses 125 RSFs, which affect 45 % of the northern slope, and up to 77 % of the sandstone cuesta slope. Among these, multi-temporal rock slides with long-runout, flow-like tongues represent the largest mass movement complexes in the range and rank among the largest in the WFC. Morphotectonic analysis suggests that the primary mechanism of gravitational failure involved backward rotation along listric-shaped structures, with vertical displacements ranging from 6 to 90 m, although the depth of gravitational disintegration may exceed 150 m. The Schmidt-hammer weathering index provides evidence for the multi-temporal activity of RSFs, identifying five distinct phases of RSF activity.

The flume experiments were conducted using four cover types (corn residue, rock fragment, sweet potato, and corn stem) with coverage ranging from 2.5 % to 70 %, under a fixed slope gradient (15°) and a constant flow discharge (1 × 10^–3 m³ s⁻¹).
