Methods of soil analysis.

TL;DR: It is demonstrated that pristine and aged biochar colloids were stable in the solutions with environmentally relevant ionic strength, and aging process might substantially increase their mobility in the subsurface.

TL;DR: In this article, the effect of different tillage systems (individual or combinations of spading, trampling and hand weeding) on rice productivity and soil ( Typic Paleudalf ) quality under in situ residue management in lowland conditions.

TL;DR: In this article, the authors investigated the influence of added organic and industrial wastes to the formation of soils in degraded landscapes left behind by past mining activities, and found that the added organic matter resulted in stable SOM-calcite complex as dense incomplete infillings mixed with secondary calcite.

TL;DR: Wang et al. as discussed by the authors explored the long-term effects of different land use types on C, N, and P stoichiometry and storage in a subtropical region, southern China.

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.
