Methods of soil analysis.

TL;DR: The modifications of soil microbial community structure and composition induced by more than 10 years of fresh and decomposed straw return was investigated and the key environmental factors were analysed.

TL;DR: A core microbiome resistant to the disturbances caused by the conversion of forests to cultivated lands and few or none exclusive OTUs for each land-use type is found, allowing to maintain at least some soil ecosystem services after forest conversion to croplands.

TL;DR: In this article, the salt adsorption ratio (SAR) in treated wastewater (TWW) for irrigation has grown noticeably in recent years, especially in arid and semi-arid regions.

TL;DR: In this paper, a 28-day sterile experiment was conducted in a tropical soil, where 57Fe-enriched Fe2+(aq) (57/54Fe = 5.884 ± 0.003) was reactivated in anoxic conditions and the aqueous and bulk pools both moved ∼7% toward the isotopic equilibrium.

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.
