Methods of soil analysis.

TL;DR: In this article, the potential mobility and bioavailability of heavy metals in the soil were analyzed by sequential extraction technique for cadmium and chromium in the area surrounding a paper mill in Assam, India.

TL;DR: In this paper, the short-term effects of compost application on soil properties of soil cropped with maize are reported, and the results demonstrate that soil amended with compost has an increased TOC content.

TL;DR: In this paper, the authors investigated wind erosion and threshold velocity in relation to soil properties using a portable wind tunnel in 60 sites of Kerman, the largest province of Iran, and found that wind erosion rates ranged from 0.03 −g −m−2 min−1 to 3.41 −g−m−m −2 min −1, indicating a wide variability in the erodibility of soils.

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.
