Methods of soil analysis.

TL;DR: In this article, the correlations between Se concentrations and soil physicochemical characteristics (sand, silt, clay, organic matter, pH and oxides of Al, Fe and Si) from preserved areas in the Jequitinhonha Valley, Minas Gerais state, Brazil were evaluated.

TL;DR: In this article, the effects of combined biochar (BC) and manure (21 and 42 Mg −1 ) applications on water vapor sorption and specific surface area were investigated for a sandy loam soil.

TL;DR: In this paper, the authors examined total Hg, free Hg(0), matrix-bound Hg and MeHg contents in soils and plant tissues from two old cinnabar mining sites (La Soterrana and Los Rueldos) in Asturias (Spain), as well as Hg transfer and translocation from soils to plants.

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.
