Methods of soil analysis.

TL;DR: In this paper, the authors quantified in situ denitrification rates in the shallow saturated zone, a dynamic portion of the landscape, across a range of hydroperiodicities, i.e., frequencies and durations of saturated conditions, as characterized by a topographic index in a small mixed land-use headwater catchment in central New York State.

TL;DR: In this paper, the available information on the system used by indigenous people for bamboo-based agroforestry systems in the Barak Valley, North East India, was described, and analytical data of different soils for their physico-chemical characteristics in relation to soil depth and the clump age.

TL;DR: The water table altitude was directly related to the temporal changes of q Field measured at a depth of 50 cm, highlighting the fact that the saturated and unsaturated zones are connected as mentioned in this paper.

TL;DR: The results highlight EDR potential to remediate metal polluted soils at neutral to alkaline pH by choosing a good enhancement solution and thus using too high current densities can be a waste of energy.

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.
