Methods of soil analysis.

TL;DR: The results showed soils were significantly enriched by both the available and total fractions of the metals in the sequences of Zn, Cu, Cd, Pb, and Ni, resulting in a lack of non-carcinogenic health risk for the local residents.

TL;DR: The results show that the Anzali wetland are highly polluted by major PAE congeners consist of DEHP and DnBP, which indicates these two phthalate esters were ubiquitous in sediments.

TL;DR: In this article, the authors investigated the impact of two elements on the performance of a pseudo continuous pedotransfer function (PTF) in predicting soil hydraulic properties, particularly the water retention curve (WRC).

TL;DR: A laboratory incubation experiment was conducted with the natural essential oil of peppermint (Mentha spicata, MS), dementholized oil (DMO), terpenes, and a chemical inhibitor dicyandiamide (DCD) as coating materials for retardation of soil urea hydrolysis and nitrification as discussed by the authors.

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.
