“…Many studies have since used CN techniques to quantify soil production (9) on slopes with contrasting lithologies and climates (e.g., Amundson et al, 2015;Anderson, 2002;Anderson & Anderson, 2010;Decker, Niedermann, & De Wit, 2011;Dixon et al, 2009;Gabet & Mudd, 2009;Heimsath et al, 1997Heimsath et al, , 1999Heimsath et al, , 2000Heimsath et al, , 2005Larsen et al, 2014;Lebedeva & Brantley, 2013;Riebe et al, 2017;Riebe, Kirchner, Granger, & Finkel, 2001;Riggins, Anderson, Anderson, & Tye, 2011;Roering, Marshall, Booth, Mort, & Jin, 2010;Small et al, 1999;Wang et al, 2018;West et al, 2013;Wilkinson & Humphreys, 2005;Yoo & Jelinski, 2016;Yoo et al, 2006). Many of these studies examined the shape of the soil production function (10) but no consensus has arisen.…”

“…The details of the soil production (9) literature, including its focus on soil (3) depth as the controller of bedrock weathering, suggest many opportunities for pedologists to help expand this research through investigations of the weathering processes themselves as they respond to depth. Indeed, these opportunities are already being explored (Amundson et al, 2015;Anderson, Anderson, & Tucker, 2013;McFadden, 2013;Persico, McFadden, Frechette, & Meyer, 2011;Wang et al, 2018;Yoo & Jelinski, 2016).…”

“…To extend soil production research, pedologists can formally describe soil and weathering profiles (6, 8) and greatly enrich soil production inquiries into environmental reconstruction (Eppes & McFadden, 2008;McFadden, 2013;Richter & Yaalon, 2012). Pedologists can help extend soil production research across complex landscapes and many more climates, vegetation types, pedoturbation processes, tectonic regimes, lithologies, and soils (e.g., Amundson et al, 2015;Heimsath, Fink, & Hancock, 2009;Wang et al, 2018;Wilkinson & Humphreys, 2005;Yoo et al, 2011). For example, all 12 soil orders in the USDA's Keys to Soil Taxonomy (Soil Survey Staff, 2014) are found on hillslopes, including youthful A over C horizon Entisols, Inceptisols with weak Bw horizons, self-swallowing Vertisols, grassland-derived Mollisols, Gelisols dominated by permafrost that freeze and thaw in many ways, loess-accretionary and paleoclimatic Aridisols, volcanic-ash laden Andisols, peat-accumulating Histosols, and even soil orders with well-developed B horizons (i.e., the Spodosols, Alfisols, Ultisols, and Oxisols).…”

“…As pedologists and geomorphologists have much to contribute to each other's work, one purpose of this paper is to clarify the terminology and introduce methods and models with regard to soil and mobile‐regolith production research. The potential for this research has been demonstrated in a variety of recent and important publications (Amundson, Heimsath, Owen, Yoo, & Dietrich, ; Dixon, Heimsath, & Amundson, ; Stockmann, Minasny, & McBratney, ; Wang et al., ; Yoo & Jelinski, ). We also wrote this paper to reinforce, if not rekindle, the soil geomorphology of Ruhe () and many others (Holliday, ) who argued for integration of these two fundamental Earth sciences (Birkeland, , ; Gerrard, ; Jungerius, ; McFadden & Knuepfer, ; Schaetzl & Thompson, ; Zinck et al., ).…”

“…Soil production (9) is also known as mobile regolith production (9). Although pedologists have discussed soil production (9) (e.g., Amundson et al, 2015;Dixon et al, 2009;Humphreys & Wilkinson, 2007;Minasny & McBratney, 2001;Schaetzl & Thompson, 2015;Stockmann et al, 2014;Wang et al, 2018;Yoo & Jelinski, 2016;Yoo, Amundson, Heimsath, & Dietrich, 2006), soil production research deserves much wider attention across the soil sciences because it is highly relevant to soil formation and soil evolution (7). Cosmogenic methods that estimate rates of soil production (9) have been most commonly used on divergent, convex-up hillslopes.…”

Geomorphologists are quantifying the rates of an important component of bedrock's weathering in research that needs wide discussion among soil scientists. By using cosmogenic nuclides, geomorphologists estimate landscapes’ physical lowering, which, in a steady landscape, equates to upward transfers of weathered rock into slowly moving hillslope‐soil creep. Since the 1990s, these processes have been called “soil production” or “mobile regolith production”. In this paper, we assert the importance of a fully integrated pedological and geomorphological approach not only to soil creep but to soil, regolith, and landscape evolution; we clarify terms to facilitate soil geomorphology collaboration; and we seek a greater understanding of our sciences’ history. We show how the legacy of Grove Karl Gilbert extend across soil geomorphology. We interpret three contrasting soils and regoliths in the USA's Southern Piedmont in the context of a Gilbert‐inspired model of weathering and transport, a model of regolith evolution and of nonsteady systems that liberate particles and solutes from bedrock and transport them across the landscape. This exercise leads us to conclude that the Southern Piedmont is a region with soils and regoliths derived directly from weathering bedrock below (a regional paradigm for more than a century) but that the Piedmont also has significant areas in which regoliths are at least partly formed from paleo‐colluvia that may be massive in volume and overlie organic‐enriched layers, peat, and paleo‐saprolite. An explicitly integrated study of soil geomorphology can accelerate our understanding of soil, regoliths, and landscape evolution in all physiographic regions.

Soil organic carbon stock assessment in forest ecosystems through pedogenic horizons and fixed depth layers sampling: What's the best one?

et al. 2022

In soil organic carbon (SOC) survey, the role of sampling approach is crucial and should not be underestimated. In this sense, the appropriateness of soil sampling by pedogenic horizons (PGH) and fixed depth layers (FDL) in forest is still a field of debate. The present work aimed to: (a) study the spatial variability of SOC concentrations and C stocks through PGH and FDL samplings in uneven-aged sweet chestnut, European beech and Norway spruce forests of the Apennine chain (Italy); (b) clarify the major advantages and drawbacks of sampling by PGH and FDL. In a representative area (18 Â 18 m) of each forest, a soil profile was investigated and eight additional sampling points were selected. The sampling was performed both by PGH and FDL (0-15 and 15-30 cm). For each forest, no SOC content and C stock differences in 0-30 cm soil depth were found between PGH (58.8 ± 5.3 g kg À1 and 103 ± 7 g ha À1 , respectively) and FDL (52.7 ± 4.3 g kg À1 and 117 ± 9 Mg ha À1 , respectively) sampling. However, under Norway spruce, PGH sampling pointed-out that C was mainly stored in Oe and Oa horizons (51.1 vs. 146 Mg ha À1 in the 0-30 cm layer). The higher coefficient of variation obtained when soil horizons were considered (from 19.2% to 72.8% for PGH and from 16.5% to 25.7% for FDL) suggested that PGH sampling preserved the information about the spatial variability within an ecosystem. The information loss about SOC vertical and spatial distribution would indicate the inability of FDL sampling to support decision-making plans addressed for sustainable use of soil resource.
