Methods of soil analysis.

TL;DR: Examination of variation in soil properties and OC and TN stocks across the different CLUS in Dura sub-catchment, northern Ethiopia suggested that introduction of suitable management practices that sustain the soil system of the CLUS with poor soil propertiesand nutrient stocks are crucial for the study area conditions.

TL;DR: In this paper, arbuscular mycorrhizal fungi (AMF) were used for growth promotion of Zea mays L. in heavy metal rich tannery sludge (HMRTS).

TL;DR: In this paper, the effects of small and frequent N addition rates on NFG abundances were investigated in a semiarid grassland in northern China, and the results showed that the NFGs abundances responded to N addition rate distinctly, highlighting that the driven processes involved in N cycling were altered by the addition rates.

TL;DR: In this article, the critical N concentration (Nc), the minimum N required for maximal crop growth has been widely used to determine crop N status, but no attempt has been made to determine the Nc dilution curve on the basis of leaf dry matter (LDM) in summer maize.

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.
