On farmland in undulating landscapes, soil organic carbon (SOC) stocks depend on landscape position. In the North American Prairie Pothole region, we compared a native prairie reference site with a nearby farm undergoing transition to perennial agriculture (“restoration”) after a century of producing annual crops. We quantified legacy effects of farming at four upland landscape positions (to 0.9-m...
Soil and bedrock influence ecosystem diversity through various means. The aim of this study was to typify forest soil catena diversity (FSCD) in the Central-European soil regions of the Czech Republic for ecosystem restoration planning. Typification was carried out through cluster analysis on Shannon-Wiener' indexes of soil and bedrock diversities and of terrain. The relationships between soil and...
Topography is one of the key factors affecting soil organic carbon (SOC) distribution and soil redistribution (erosion or deposition) because it influences the gravity-driven movement of soil by water flow and tillage operations. In this study, we examined impacts of sixteen topographic metrics derived from Light Detection and Ranging (LiDAR) data on SOC distribution in agricultural fields. We adopted...
Mulching is an effective soil conservation practice for permanent gullies in southern China. Knowledge of the sediment characteristics that occur in mulched soils of colluvial deposits could improve the utility of mulching for soil conservation. A rainfall simulation experiment was designed to evaluate the effects of mulch on the runoff, erosion, and particle size distribution of eroded sediments...
The sustainability of agroecosystems is closely related to successful soil conservation. Sustainable land use practices are crucial to reduce the impacts of agriculture on land degradation and maintain long-term soil productivity. In this context, is important to avoid practices that deteriorate the soil (e.g. soil erosion), and find the most suitable to maintain soil and crops productivity. The objective...
Biocrusts are a crucial component of desert ecosystems, playing a significant role in greenhouse gas fluxes when they cover soils. However, little is known about whether, and how sand burial, one of the most common disturbances affecting the biodiversity and ecological function of biocrusts, influences fluxes of CO2, CH4, and N2O from the desert biocrust-covered soils. Based on measurements of the...
This article focuses on short-term changes in the thermal conditions and thickness of the active layer during the summer season of 2015, observed in test fields located in the tundra and the beach areas in the Kaffiøyra region Svalbard. The purpose was also to attempt a detailed analysis of short-term relationships between the rate and the dynamic of ground thaw and air temperature, as well as to...
Flood plain ecosystems show significant soil spatial variability. Understanding spatial variations of soil texture fractions and pH in flood plains is necessary for ensuring proper management of these plains, because these properties influence soil structure, fertility, hydraulic conductivity, infiltration, and erosion. In the present study, the distribution of soil texture fractions and pH was investigated...
Salinity affects phosphorus (P) fractionation and its availability in soil and thereby crop growth as well as yields. Therefore understanding of P transformation and availability in soil with use of different sources of P is crucial to adopt appropriate P management practices for improving productivity of saline soils. A field experiment comprising of four treatments replicated thrice was conducted...
Soil erosion is a threat to sustainable agricultural and regional development in karst regions. In this study, field plot observation method was used to estimate the effects of slope gradient and length on runoff and soil loss in Guizhou, Southwest China. The results showed that runoff and soil loss is nonlinearly related to slope gradient. The increasing trends of runoff and soil loss declined after...
The impact of the Wallachian settlement on small mountain catchments has been studied at the example of Škorňanský and Hartisov Streams (Moravskoslezské Beskydy Mts, Western Outer Carpathians). Between the 16th and the 19th centuries the Wallachian people introduced pastoral management originating from the woodless Balkans to the forested mid-altitude mountain area under study. This area was subjected...
Although metal accumulation has been investigated in coastal Antarctic soil, the information about to what extent station activities influence soil quality remains limited, especially in East Antarctica. Here, we carried out an investigation on element accumulation (Pb, Zn, Cu, Ni, Mn, Cr, Ti, Zr, Fe, Ca, K, Al, Mg and Na) in topsoils collected from Larsemann Hills, the second largest oasis along...
The presence of livestock creates a “three-phase-mosaic” pattern of dominant surface patches: shrubs, trampling routes, and intershrub areas. These patches differ in soil properties, runoff generation, and sediment production; runoff yield is highest in the routes. In light of knowledge that the productivity of arid and semiarid ecosystems is controlled primarily by water dynamics, the spatial correlation...
The Pampean aquifer, in south east Argentina, is mainly constituted of loess-like sediments. These are clastic sediments mainly composed of quartz and aluminosilicates and calcrete concretions. Its hydrochemistry is generally studied assuming a chemical equilibrium between mineral phases and the aqueous fluids. The phases forming the matrix of this aquifer are considered to be the reactive phases...
The Zoige Basin is located in the northeastern Tibetan Plateau, at an altitude of around 3500m. To fully understand and assess the current status and future trend of aeolian activity in the Zoige Basin, it is necessary to reveal the history of aeolian activity of this region. In this study, 11 Optically stimulated luminescence (OSL) ages from three typical sections were used to reconstruct the history...
Badlands in Central Istria share a very frequent characteristic with other worldwide badland sites, the rapid erosion rate. Rock wall retreat measurement on such a relief is associated with all types of problems because a certain effort has to be put into the measurement equipment design. Spear vegetation and a few previous studies encouraged the testing of different photogrammetric technologies and...
Soil spatial variability has become the rule rather than the exception; it is the consequence of spatial dependence, periodicity, nonstationarity, and nonlinearity. The continuous wavelet transform (CWT) has been extremely useful in revealing scale- and location-specific information of nonstationary soil spatial variation. The Hilbert–Huang transform (HHT) has also been used in soil science to reveal...
Covering the surface of stony slopes with a layer of topsoil is one of the most commonly used techniques to restore quarries. However, in semiarid climates, the topsoil is frequently poor and has limited water availability, which significantly reduces the success of the restoration. The high water-holding capacity of the sludge from the cutting and polishing of marble, as highlighted in previous studies,...
In Sabah, Malaysia, ultramafic rock outcrops are widespread (totalling 3500km2, one of the main outcrops in the tropical zone), and predominantly of the peridotite type. However, strongly serpentinised peridotite is also locally common, particularly along fault lines in the Mt. Kinabalu area. This study aimed to determine the extent of chemical variation in ultramafic soils in relation to the degree...
