Methods of soil analysis.

TL;DR: Pedotransfer rules, predicting the Freundlich sorption coefficients, could be applied for prediction of pharmaceutical mobility in soils with similar soil properties and together with pharmaceutical half-lives and other imputes may be used for assessing potential ground-water contamination.

TL;DR: In this article, the authors evaluated the long-term effects of no-tillage and conventional tillage practices on soil organic carbon and its fractions at different depths ranging from 0 to 60 cm in Shanxi, China.

TL;DR: The results suggest that the transport of vanadium to the subsurface is controlled primarily by the leaching processes occurring in soils, indicating the potential for high vanadium release following periods of drought.

TL;DR: In this article, a replicated 5-year field study was conducted to evaluate the effects of six combinations of three tillage and crop establishment (TCE) techniques and two residue management options on soil physical properties, system productivity and economics of an irrigated RMS in north-west India.

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.
