Summary: The study analyzed 356 samples from the south-western region of France to determine the spatial distribution and origin of six trace elements in soils. It found that the element arsenic has dual anthropogenic and geogenic origins, while cadmium is mainly geogenic and associated with Jurassic limestone bedrock.

Summary: This study used GIS-based geostatistics and multivariate analysis to estimate the spatial variability of soil physico-chemical characteristics in Sultan Batheri Block, Wayanad district. A total of 32 soil samples were collected and analyzed using standard analytical techniques. The results showed high variation in soil organic carbon and low variation in electrical conductivity. Principal component analysis and correlation coefficient matrix analysis revealed the interrelationships among soil properties. Spatial distribution of soil characteristics was developed using inverse distance weighting and kriging methods, which exhibited high accuracy according to cross-validation tests. The levels of nitrogen and phosphorus in the study area were found to be ideal, indicating no contamination risk.

Summary: The study revealed that urban soils in Yazd City have high concentrations of toxic metals, especially As, Cd, and Pb, leading to considerable pollution in the area. The quality of urban soil in the study area is significantly influenced by toxic metals, particularly due to the prevailing wind direction, the route of the north-south highway of Iran, and the population density and traffic in certain areas.

Summary: The objective of this study was to assess the pollution level, sources, and potential risk of heavy metals and arsenic in four dry riverbeds affected by mine tailing. Various analytical techniques and indices were used to identify the sources of contamination and assess the pollution status. The results indicated that the mine wastes were the main source of metal(loid) contamination in the dry riverbeds.

Summary: The study revealed that while the overall soil quality in the upstream watershed of the Guanting and Miyun Reservoirs in Beijing is excellent, there are relatively high contamination risks for Cd, Cu, Zn, and Cr. Through the analysis of heavy metal concentrations, factor analysis, and cluster analysis, the sources of different heavy metals were identified.

Summary: This paper comprehensively analyzed the soil characteristics and fertility of cultivated land in Xuwen County using geostatistics, geographic information system (GIS), and fuzzy mathematics. The results showed that the overall level of soil fertility in Xuwen County is above average, with a trend of high fertility in the South and low fertility in the North. These findings provide theoretical guidance for improving fertilizer utilization, fine management of cultivated land, and ecological environment.

Summary: This study analyzes samples from the Soil Quality Measurement Network in southwestern France to determine the spatial distribution and origin of silver in the soils. The results show a range of silver concentration in the soils and correlations with other metals and distance to mining sites. Cokriging is used to estimate the spatial distribution of silver, and it improves the quality of interpolation compared to ordinary kriging.

Summary: The purpose of this study is to investigate the trace metal contents in soils, determine their spatial distribution, and identify their potential natural or anthropogenic sources. The results indicate that Cr and Fe are predominantly derived from natural sources, while Pb and Zn come from industrial sources, and Cu comes from agricultural and industrial sources. The hotspot areas of metal contamination are mainly concentrated around the Arcelor Mittal complex.

Summary: The study aimed to identify and rank the covariables of soil-forming factors that affect the distribution and spatial variability of pH in an agricultural area, and to obtain a predictive map of soil pH. The results showed that particle size and human activity had the most influence on the spatial behavior of pH.

Summary: This study focuses on evaluating the spatial variability of soil chemical attributes under different agricultural use and native forest in the Amazonas state. The results show that multivariate analysis can identify the attributes that contribute the most to the variability of these soils, and that the forest has less spatial variability.

Summary: This study analyzed the spatial distribution and influencing factors of soil nutrients in the semiarid Anding district farming region in northern China. The results showed considerable variability in soil nutrient content, with soil organic matter, total nitrogen, and available phosphorus showing increasing trends from the middle to the northeast and southwest, while available potassium showed the opposite trend. Factors such as soil texture, irrigation method, and water source type significantly influenced the distribution of soil nutrients.

Summary: Investigation of heavy metal pollution degree, pollution sources, and spatial distribution structure is crucial for the country's soil pollution prevention, but relevant research is lacking. In this study, researchers investigated the pollution levels and sources of As, Cd, Cr, Cu, Pb, and Zn in the national scope. The study found that Cd had the highest pollution level and identified four sources of contamination for Cr, Cd, Zn, and As. The geographical detector analysis revealed the influence of different factors on the spatial distribution of heavy metals.

Summary: Plant-soil feedback mechanisms in temperate grasslands can lead to the formation of 'fertility islands' under clumps of the tall-grass invader B. rupestre, with high levels of phosphorus and amino acids present under these patches. Soil microbial biomass plays a role in modulating nutrient accumulation, suggesting factors other than plant biomass may contribute to high fertility in these areas. The spatially explicit approach used in this study provides insights into how herbivory can influence the stability and expansion of invasive plant species.
