Methods of soil analysis.

TL;DR: A combination of a multivariate (geo) statistic approach and a bioavailability assessment allowed us to efficiently identify sources of contamination and potential risks in two districts of a highly populated and industrialized city.

TL;DR: In this article, the authors determined the hydraulic properties of three trimmed samples of weathered granitic bedrock (referred to as Samples A, B, and C, in order of size) in the laboratory Silicone rubber was used to fill the space between each sample and the surrounding cylinder wall.

TL;DR: In this paper, soil quality indices (SQI) are used to evaluate the degradation of soil quality in the conversion of forest to agricultural land, which is a major worldwide concern and a cause of environmental and soil quality degradation.

TL;DR: In this article, a 3-year in situ experiment was carried out in a dual copper (Cu)/cadmium (Cd)-contaminated farmland in order to explore the combined remedy effect of alkaline materials and plants on the distribution of heavy metals in whole soil and aggregates.

TL;DR: In this paper, the authors present a modeling approach aimed at seasonal resolution of global climatic and edaphic controls on patterns of terrestrial ecosystem production and soil microbial respiration using satellite imagery (Advanced Very High Resolution Radiometer and International Satellite Cloud Climatology Project solar radiation), along with historical climate (monthly temperature and precipitation) and soil attributes (texture, C and N contents) from global (1°) data sets as model inputs.

TL;DR: In this paper, the Century ecosystem model was applied to a series of forest and grassland sites distributed globally to examine large-scale controls over soil carbon, including soil texture and foliar lignin content.

TL;DR: In this article, the Rothamsted model is used to calculate the amount of CO2 that would be released from the world stock of soil organic matter if temperatures increase as predicted, the annual return of plant debris to the soil being held constant.

TL;DR: In this paper, the formation of soil structure involves the physical forces of shrinking and swelling created by changes in water status of soils, freezing and thawing, tillage, or by movement of the larger biota in soils.
