“…Soil Properties Sand dominated the particle size fractions of the soils developed over the three parent materials and constituted > 700.00 g kg -1 (Table 1), resulting in dominantly loamy sand and sandy loam textures with few sandy clay loam textures. Sand was previously reported to dominate soils developed on basement complexes (Sadiq et al, 2021), and this dominance over the clay and silt particles was attributed to the .70 TC -Textural class, LS -Loamy Sand, SL -Sandy Loam, SCL -Sandy Clay Loam; PG -porphyritic granite, PT -pegmatite, GG -granite-gneiss; CP -crest, US -upper slope, MS -mid slope, LS -lower slope granitic origin of the complex (Maniyunda, 2012;Shobayo, 2019). Soil texture is an important criteria for FCC, such that soil texture alongside drainage have been used as criteria for the creation of agroecological units in the beach sands area of Akwa Ibom State (Udoh and Ibia, 2022).…”

A clear understanding of soil characteristics and their appropriate classification are essential for efficient land use and increased productivity. The present study was carried out to obtain the fertility capability classification (FCC) of the soils overlying the basement complex in a toposequence in north eastern Nigeria and to serve as baseline data for soil management. Soils on four topographic positions identified on porphyritic granite (PG), pegmatite (PT) and granite-gneiss (GG) of the basement complex in Taraba State of Nigeria were assessed. Twelve pedons were studied in all, four along the toposequence on PG, PT, and GG. At the type and substrata type, sandy and loamy group dominated. Ustic soil moisture regime, exchange acidity (fixing available phosphorus) and low organic carbon limited the entire soils across the basement complexes restricting rainfed crop production to one season per annum except with irrigation practice. Poor drainage was a limitation across the soils on pegmatite. The FCC rated PG and GG soils as SLdeam (sand over loam and limited by moisture, effective cation exchange capacity, aluminium toxicity and organic carbon) and Ldam (loam type and substrata characteristics limited by moisture, aluminium toxicity and organic carbon), and PT and PT soils as Sdamg (sandy type and substrata type restricted by moisture, aluminium toxicity, organic carbon, drainage). Ridge construction, organic and mineral fertilizer applications are essential management practices required for sustainable use of these soils.

Sadiq, FK et al [18] focused their research on Nigeria's semi-humid agricultural zone, the main limiting factors of basal complex soil were evaluated using the MDS to provide complete information on crop production. Yu PJ et al [19] constructed the MDS based on PCA and total data set (TDS) to evaluate the short-term effects of various land use patterns on SQ in the semi-arid and alkaline grasslands of Northeast China.…”

It is imperative to comprehend the influence of reclamation on soil quality (SQ) and function to implement effective soil restoration strategies for a particular area. The primary objective of this study was to develop soil quality indexes (SQIs) to reveal the changes in SQ during the restoration of vegetation in the reclaimed waste dumps of the Hequ open-pit coal mine. The study built an SQI evaluation model for waste dumps based on the soil management assessment framework (SMAF). The total data set (TDS) consisted of nine physicochemical property indicators that were subsequently analyzed. The selection of the minimum data set (MDS) involved the utilization of principal component analysis (PCA) and Norm values. The SQ was comprehensively evaluated for nine indicators, taking into account the non-linear membership function and the improved Nemerow index. The weighted additive method was employed to compute three SQIs, all of which yielded satisfactory outcomes. The findings suggested a noTablele disparity in the SQ between the reclaimed area and the unreclaimed area, yet the overall SQ fell short. The sequence of SQ in various waste dumps was as follows: No.4lower>No.1> No.2> No.3> No.4upper. The non-linear membership function indicated that pH, available nitrogen (AN), available phosphorus (AP), surface moisture content (SMC), and bulk density (BD) were crucial in limiting SQIs in total waste dumps. The crucial limiting SQIs in unreclaimed areas were total phosphorus (TP) and total nitrogen (TN). This analysis demonstrates its efficacy in formulating strategies for the SQ evaluation and targeted soil reclamation plans of waste dumps.

“…Understanding how soil water chemistry varies across topographic features within these regions is essential for managing forest and water resources, especially when considering anthropogenic climate change and disturbances in montane systems (Covino, 2017;Dai et al, 2018;Bukoski et al, 2021). Topography influences surface and subsurface hydrology, and thus spatial patterns of vegetation, soil chemistry, and nutrients (Seibert et al, 2007;Molina et al, 2019;Sadiq et al, 2021). Topographically-driven flowpaths influence soil structure via weathering, altering the physical and chemical characteristics and hydrologic capacities of soils (Hook and Burke, 2000;Seibert et al, 2007;Sadiq et al, 2021).…”

Topographically-driven flowpaths influence soil structure via weathering, altering the physical and chemical characteristics and hydrologic capacities of soils (Hook and Burke, 2000;Seibert et al, 2007;Sadiq et al, 2021). With climate change impacting montane zone dynamics at a disproportionally high rate, understanding topographic variation in soil solutes and their control on water quality is of growing importance (Seidl et al, 2017;Langhammer and Bernsteinová, 2020;Hale et al, 2022).…”

Biogeochemical properties of soils play a crucial role in soil and stream chemistry throughout a watershed. How water interacts with soils during subsurface flow can have impacts on water quality, thus, it is fundamental to understand where and how certain soil water chemical processes occur within a catchment. In this study, ~200 soil samples were evaluated throughout a small catchment in the Front Range of Colorado, USA to examine spatial and vertical patterns in major soil solutes among different landscape units: riparian areas, alluvial/colluvial fans, and steep hillslopes. Solutes were extracted from the soil samples in the laboratory and analyzed for major cation (Li, K, Mg, Br, and Ca) and anion (F, Cl, NO2, NO3, PO4, and SO4) concentrations using ion chromatography. Concentrations of most solutes were greater in near surface soils (10 cm) than in deeper soils (100 cm) across all landscape units, except for F which increased with depth, suggestive of surface accumulation processes such as dust deposition or enrichment due to biotic cycling. Potassium had the highest variation between depths, ranging from 1.04 mg/l (100 cm) to 3.13 mg/l (10 cm) sampled from riparian landscape units. Nearly every solute was found to be enriched in riparian areas where vegetation was visibly denser, with higher mean concentrations than the hillslopes and fans, except for NO3 which had higher concentrations in the fans. Br, NO2, and PO4 concentrations were often below the detectable limit, and Li and Na were not variable between depths or landscape units. Ratioed stream water concentrations (K:Na, Ca:Mg, and NO3:Cl) vs. discharge relationships compared to the soil solute ratios indicated a hydraulic disconnection between the shallow soils (<100 cm) and the stream. Based on the comparisons among depths and landscape units, our findings suggest that K, Ca, F, and NO3 solutes may serve as valuable tracers to identify subsurface flowpaths as they are distinct among landscape units and depth within this catchment. However, interflow and/or shallow groundwater flow likely have little direct connection to streamflow generation.
