Methods of soil analysis.

TL;DR: In this paper, the acid-treated rice husk biochar (RHB) was prepared by treating RHB with three acids (HCl, HNO3, H 3 PO4), each applied at 2 levels (25 N and 5 N).

TL;DR: The results showed that ISA tripled from 1990 to 2010 displacing remnant desert and cropland, mainly in the northern city and the urban landscape, especially the greenspaces, became obviously fragmented.

TL;DR: The ecosystem resilience gave rise to the selection of AMF species better able to thrive in soils with higher microbial activity and, thus, to higher soil fertility, as no negative effects were observed on crop vitality and productivity.

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.
