Methods of soil analysis.

TL;DR: In this article, the authors studied the dynamics of aggregate formation and associated soil organic carbon transferring among different aggregate fractions using an isotopic tracer technique (14C-labeled wheat residues).

TL;DR: DNA-based stable-isotope probing was applied to identify the active microorganisms involved in syntrophic butyrate oxidation in paddy field soil and members of the Planctomycetes and Chloroflexi were also labeled with 13C by yet-unclear mechanisms.

TL;DR: In this paper, the authors investigated the potential of riparian wetlands to mitigate nutrient pollution to the aquatic environment when they serve as biogeochemically active buffer zones between arable land and water bodies and concluded that riparian ecosystems with only minor disturbances are not generally to be considered as hotspots of N 2 O emissions in the landscape.

TL;DR: In this paper, the authors applied Fe K-edge extended X-ray absorption fine structure (EXAFS) spectroscopy and pair distribution function (PDF) analysis of high-energy Xray scattering to investigate the effects of bivalent cation-oxyanion pairs on the structure of Fe(III) precipitates formed from the oxidation of Fe (II) generated by the electrolytic dissolution of Fe 0) electrodes.

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.
