Soil richness was examined across the Wisconsin ecological tension zone, which constitutes a transition between the central hardwood forest and prairie biomes to the south and the northern mixed hardwood and conifer forest biome to the north. There were greater numbers (normalized by county area) of soil orders, suborders, and great groups in counties within the transition zone than in those outside...
Many river systems, within New Zealand and globally, have experienced rapid acceleration in floodplain sedimentation in response to anthropogenic catchment disturbance, creating significant issues (i.e., flooding and water quality). Reconstruction of past river responses to environmental- and anthropogenic-driven changes in sedimentation and erosion can provide valuable insights into these river dynamics...
Having accurate soil erosion intensity/type maps using satellite imagery is not generally a difficult task. However, there are still difficulties for the generation of small scale erosion features at regional and national levels. It is even more problematic when high-resolution satellite images cannot be used due to their high cost at a regional level. The principal objective of this study is to investigate...
In temperate zones, an idealized profile of the regolith would consist of in descending order and decreasing weathering intensity, zones I, II, III, and IV. Each zone is characterized by a distinctive mineralogy and chemistry that reflects reactions between rocks and downward percolating fluids. Utilizing these principles, we attempted to reconstruct the original position within the regolith of erosionally...
Nile Delta includes part of the most fertile and populated lands in the world. However, there is no accurate and reliable database about C and N pools of this region; in addition there are no published data in this regard. Spatial variation of soil C and N pools was studied based on Ordinary Kriging (OK) as a geostatistical method. This method was used for converting sampled soil C and N data to continuous...
Mountain environments are heterogeneous and dynamic geomorphic environments sensitive to land use and climate change. Heterogenic environmental conditions result in a large variability of mountain soil properties, and thus in large uncertainties of inventories of soil organic carbon (SOC). In this study we analyzed the variability of soil properties associated with the calculation of a SOC inventory...
Soil organic carbon and nutrient content are analysed at topsoil cm-scale in a Rendzic Phaeozem from an Aleppo pine forest in semiarid Central Ebro Basin (NE-Spain). Soil depth affected by a severe wildfire is studied immediately after burning and a year later, trying to differentiate the heat shock and the ash/charcoal deposition effects. One week after the wildfire, soil organic carbon content (SOC)...
The Sneeuberg uplands in the eastern Karoo are wetter than lowland sites with >400mm of rainfall. For over 150years, until recently, they have been overgrazed: largely by sheep. The landscape consists of badlands, less degraded areas and networks of gullies occupying the valley floors and hillside depressions. These gullies have been relatively stable since at least 1945. The age of the gullies...
Long-term fertilization has a significant impact on total soil organic carbon (SOC) stock. However, fertilization impact on physical fractions of SOC is still poorly understood for red soils in southern China. This study assessed the impact of 17years (1990–2007) of long-term fertilization on the changes in different SOC fractions under an intensive maize (Zea mays L)–wheat (Triticum Aestivium L)...
In this paper, temporal variations in the hydrological process of the Pearl River delta (PRD) are examined based on monthly datasets for water discharge, sediment load and suspended sediment concentration (SSC) since the 1950s using the methods of power spectrum analysis and Fourier transform. In addition, the underlying causes of the variations are examined to address the influence of diverse human...
Climate change has huge impacts on alpine ecosystems. One of the most visible effects in the Alps is glacier retreat since the end of the Little Ice Age (LIA), which caused the exposure of previously glaciated surfaces. These surfaces are open-air laboratories, verifying theories regarding ecosystem and soil development.In order to increase our knowledge on the effects of time and vegetation primary...
Arsenic is a highly toxic element and its presence in foodstuffs will do harm to human health. In this study, the levels of arsenic in the fruits of three mango cultivars (Mangifera indica L.) from Hainan Island, China were investigated and their relationships to soil properties were discussed. The concentrations of arsenic in the mango fruits ranged from 0.6 to 50μgkg −1 (FW) with a mean...
In the framework of the EU-INTERREG-IVb-project ForeStClim (Transnational Forestry Management Strategies in Response to Regional Climate Change Impacts) a combination of experimental methods has been applied for the investigation of the spatial and temporal variation and intensity of overland flow generation and soil erosion processes.In the presented study, the influences of land-use type and land-management...
Many environmental scientists are analysing spatial data by geostatistical methods and interpolating from sparse sample data by kriging to make maps. They recognize its merits in providing unbiased estimates with minimum variance. Several statistical packages now have the facilities they require, as do some geographic information systems. In the latter kriging is an option for interpolation that can...
A myriad of soil classifications exist internationally. These usually cater for unique national variations and conditions. These different classification systems, however, hinder international communication. This paper attempted to relate the South African Soil Taxonomic (SAT) soil classification system with the World Reference Base for Soil Resources (WRB) through taxonomic distance classification...
A controlled trampling study was conducted in Nigde–Aladag Mountains Natural Park, a popular destination for recreational activity, to explore the short-term impacts of different trampling intensities (0, 25, 75, 200, 500 passes) on soil and vegetation. Short-term recreational trampling activities do not significantly affect most of the topsoil properties. The most affected soil properties are total...
The problem of maintaining soil quality and fertility of soil developed from Pleistocene eolian sand deposits arises from improper management and conservation of the highly fragile sandy soil environment. The research was undertaken to determine how various aspects of cultivated soil fertility can be related to specific pedological and geological factors, and which one of these relationships plays...
The changes of soil hydraulic properties under early-stage (from several years to a few decades) natural vegetation recovering are not well understood in semiarid zones. We hypothesized that early-stage vegetation recovering can change measurably soil hydraulic properties and this would behave differently from long-term (from several decades to hundreds of years) vegetation recovering. This study...
