This study fully considers the characteristics of expressways in mountain areas. The catchment area is considered a prediction unit. The method of slope division is improved, and a method of improving the parameters in the model is proposed. Comparison and analysis with actual observation data show that the method of soil and water loss prediction adopted in this paper has less error and higher prediction accuracy than other models and can satisfy prediction requirements.

This paper describes methodological experience and provides data references for international counterparts to study soil erosion in karst landform areas. The lithological and desertification factors introduced in the soil erosion model accurately reflect and predict soil erosion conditions and spatial distribution characteristics in karst areas. Future studies on soil erosion in karst areas should include underground loss in the calculation scope.

Due to the soil holding capacity is very limited in karst area, it is necessary to consider the allowable loss of soil. Here we took thermodynamic dissolution model of carbonate rocks and the lithological characteristics to estimate soil loss tolerance, then corrected and quantitatively evaluated the soil erosion. We identified the spatial pattern of soil loss tolerance in karst area, found RUSLE overestimated soil erosion in karst area and proposed an idea for evaluating soil erosion in karst.

In karst mountainous areas in Southwest China, sloping land is overly reclaimed. Why are farmers doing this? Through typical case studies of peak-cluster depression areas, we found that low land carrying capacity and high population pressure where farmers carry out extreme steep reclamation activities are the main reasons for desert-like landscapes; this is a kind of land degradation which occurs in vulnerable karst dryland socioecological systems.

Short summary
For accurately reflecting the eco-hydrological process of the dual structure of the surface and subsurface, we propose a new method for the extraction of small watersheds in karst regions. In this study, we think that the minimum karst watershed has an exit at the corrosion–erosion datum, and the further karst sub-watershed division may cause an eco-hydrological fault. The watersheds delineated by our method accurately reflect the hydrological process in the Sancha River.

Soil erodibility (K) is one of the key factors of soil erosion. Selecting the optimal estimation method of soil erodibility is critical to estimate the amount of soil erosion, and provide the base for sustainable land management. This research took the Loess Plateau of China as a case study, estimated soil erodibility factor with different methods, selected the best texture-based method to estimate K, and aimed to understand the indirect environmental factors of soil erodibility.

Physical aspects and knowledge of soil erosion in six rural communities in Chiapas, Mexico, were assessed. Average erosion rates estimated using the RUSLE model ranged from 200 to 1200 ha−1 yr−1. Most erosion rates were relatively high due to steep slopes, sandy soils, and bare land cover. The results of a knowledge, attitudes, and practices (KAP) survey showed that some communities with high erosion rates also had less knowledge of and more negative attitudes towards soil erosion management.

The speed of land use changes is much higher than in the past, which led to many changes in the environment and ecological processes. These changes cause some changes in the climate, the amount of pollution and biodiversity. Monitoring and modeling historical situation of the region can be used to anticipate the negative effects of these changes in order to protect resources. Agriculture class will be faced with a huge reduction of carbon sequestration because of expansion of residential areas.

The soil texture representation with the standard textural fraction triplet sand–silt–clay is commonly used to estimate soil properties. The objective of this work was to test the hypothesis that other fraction sizes in the triplets may provide a better representation of soil texture for the reconstruction of the particle size distribution and for estimating some soil properties with soil texture as a predictor. The results supported the hypothesis.

The severity of land degradation was assessed by analysing the physico-chemical parameters and correlating with satellite data in the Bathinda district, Punjab. Most of the soil samples were slightly or moderately saline, while a few were calcareous and alkaline. Comparing the satellite datasets of 2000 and 2014 revealed an increase in settlements and a decrease in barren area. The study can be useful for soil and environmental scientists and planning agencies for restoration of degraded lands.

Andic soils have unique morphological, physical and chemical properties that induce both considerable soil fertility and great vulnerability to land degradation. Here we attempt to show that soils rich in poorly crystalline clay minerals have an utmost ecological importance.
Our results are hoped to be a starting point for better understanding the ecological importance of andic soils and also possibly to better consider pedological information in carbon balance calculations.

The influences of land-use conversion on soil properties and bacterial communities were assessed. Diversity was detected in four distinct land-use systems through high-throughput sequencing. Land-use changes affected soil properties and bacterial community structures. The microbial dominant taxa were unchanged, but their relative abundances were significantly different, indicating that the effects of land-use conversion on bacterial communities were more quantitative than qualitative.

Cocoa agroecosystems are a major land use type in West Africa, reportedly associated with the problem of soil degradation. This study developed a composite soil degradation assessment index (CSDI) for determining the degradation status of cocoa soils under smallholder farming systems in southwestern Nigeria. The newly developed index can show early warning signs of soil degradation, which can help farmers and extension officers to implement rehabilitation practices on degraded cocoa soils.

We studied the effect of land conversion and erosion intensity on the biogenic silica (BSi) pools in a subtropical soil in the south of Brazil. Our study shows that deforestation will rapidly (< 50 years) deplete (10–53 %) the biogenic alkaline extractable Si (AlkExSi) pool in soils. Higher erosion in steeply sloped sites implies increased deposition of biogenic Si in deposition zones near the bottom of the slope, where rapid burial can cause removal of BSi from biologically active zones.

The aim of this study is to relate the potential of land for a particular use in a given region with the actual land use. To this aim, the impact of several land cover flows related to urban development on soils with good, average, and poor production potentials were assessed and mapped. Thus, the amount and quality (potential for agricultural production) of agricultural land lost between the years 2000 and 2006 and the regions with major impact (hot spots) in Europe were identified.

Two fire-affected soils have been studied using micromorphological methods. The objective of the paper is to assess and compare fire effects on the micropedological organisation of soils in a forest-steppe zone of central Russia. The burnt soils differ from the control on a macromorphological level only in the upper part of the profile where the litter is transformed to ash identified as a dim grey organomineral mixture. Processes of soil erosion are clearly manifested 1 year after the fire.

Soil is a sphere of the earth system with a special structure and function. From the point of view of the earth system, soil science should not only study the soil material but also change towards the relationship between the soil and the
earth system, which has a profound impact on the human living environment and global change research. The results show the relationship between soil Atterberg limits and the occurrence mechanism of collapsing gullies, which can be used as a reference.

Soil and water losses in agriculture are a major environmental problem on the Loess Plateau, China. This study investigated the effects of wheat stubble on soil erosion in laboratory plots under simulated rainfall. These results show that the traditional plow may induce more serious soil and water losses compared to wheat stubble cover. Wheat stubble cover delayed runoff generation time, decreased the runoff and sediment loss, and increased rainwater infiltration into the soil.

Organic matter addition is an efficient way of reducing the effects of field traffic. The depth-dependent (0–10 and 10–20 cm) changes in some physical soil traits such as penetration resistance, bulk density, and porosity as a function of tractor passes and organic matter addition to clay soil.
The enhancing effects of treatments on the investigated parameters were C>GM>FYM. The increase in tillage lines made the soil properties worse and corresponded with the type of organic matter.

Al toxicity to plants and soil infertility in acidic soils are the main limiting factors for crop growth. To establish which acid soils need to be ameliorated for plant growth, the parameters of critical soil pH and soil Al concentration must be determined. The critical soil pH and exchangeable aluminium of two Ultisols for wheat and canola production were determined in this study. The results obtained will provide useful references for the utilization and management of acid soils.

This is an interesting piece of work and makes a nice contribution to the knowledge on how aboveground vegetation can control belowground soil properties through functional traits and functional diversity. Functional traits are the center of recent attempts to unify key ecological theories on species coexistence and assembly in communities. The results presented are valuable for understanding the relationship between species traits, functional diversity, and soil properties.

This study was conducted to estimate the rate of soil erosion and to evaluate the existing SWC strategies in the Koga watershed. A mixed approach of field investigation and an integrated RUSLE model modified for Ethiopian highlands is being adopted for soil erosion assessment. Most of the existing SWC structures fail to meet the standard due to deficient construction and management of SWC structures. The soil erosion rate is by far higher than the tolerable soil loss rate.

The soil properties of Batumi delta, an important area for agricultural production and biodiversity in the southwest of Georgia, have not been studied yet. In order to provide scientific data, soil samples were taken from different points of delta and their basic characteristics were determined. At the end of the study, the results indicated that the soil properties were affected by the formation time and land use, and the relations between the soil properties varied depending on these factors.

The development of alternative low-cost and low-environmental-impact revegetation methods is necessary for the effective management of Mediterranean forest environments. This research assessed the effects of five types of soil amendment on the success of afforestation processes. In terms of land management, the study shows that the addition of mulch or hydroabsorbent polymer can reduce transplanting stress and improve the success of afforestation programs.

In this study the features of pedogenic evolution of four soil profiles formed in topographically different positions of the southwestern–northeastern direction were investigated. The results of the study showed a strong relationship between the topography and some of the soil’s morphological, mineralogical, physical and chemical characteristics. Soil depth and physical soil features such as texture, structure and bulk density were found to improve downwards within the toposequence.

Climate and soil surface conditions influence the erosive capacity of the wind, causing loss of soil productivity. Wind erosion leads soil drying and its loss of nutrients, and this in turn is conditioned by soil surface compaction. The impact of management on most of soil properties and on its wind erodibility determines agricultural productivity and sustainability. We used a new wind tunnel to evaluate all these acts.

Short summary
First, we report the following discovery: T values are spatially heterogeneous, and a minimum of three criteria should be considered instead of only a single criterion in karst areas. In fact, our findings disprove the old “one region, one T value” concept.
Second, we proposed a new viewpoint: in karst regions, a large soil erosion modulus does not correspond to severe soil erosion. Although T value can reflect soil sensitivity, this value cannot indicate soil erosion risk.
First, we report the following discovery: T values are spatially heterogeneous, and a minimum of...
