Rice straw application with different water regimes stimulate enzymes activity and improve aggregates and their organic carbon contents in a paddy soil
Ibrahim Mohamed,Mohamed Bassouny,Mohamed H.H. Abbas,Zhan Ming,Cao Cougui,Shah Fahad,Shah Saud,Jabar Zaman Khan Khattak,Shamsher Ali,Haythum M.S. Salem,Ahmed Azab,Maha Ali +11 more
TL;DR: Results revealed that application of rice straw at a rate of 15 g kg-1 increased the activities of dehydrogenase, urease, neutral phosphatase and catalase enzymes within the first 60 days after application; thereafter, activities of the first three enzymes decreased considerably; and carbon content within aggregates sized <250 μm were significantly correlated with the percentage of these aggregates in soil.

Soil organic carbon and particle sizes mapping using vis-NIR, EC and temperature mobile sensor platform
TL;DR: Results from this study indicate that robust calibration models can be developed on the basis of the Veris mobile sensor platform and that high resolution field maps of soil properties can be compiled in a cost-effective manner.

Reducing phosphorus losses from over‐fertilized grassland soils proves difficult in the short term
M. Schärer,Christian Stamm,T. Vollmer,Emmanuel Frossard,Astrid Oberson,Hannes Flühler,Sokrat Sinaj +6 more
TL;DR: In this paper, three management options to reduce P in runoff from grassland soils were evaluated in a field experiment lasting 2 years on two grassland sites: (i) no P inputs, (ii) no p inputs plus soil tillage and (iii) noP inputs plus tillage combined with application of a P sorbing soil amendment (iron oxide).

Combining chemical sequential extractions with 3D fluorescence spectroscopy to characterize sludge organic matter.
Mathieu Muller,Julie Jimenez,Julie Jimenez,Maxime Antonini,Yves Dudal,Eric Latrille,Fabien Vedrenne,Jean-Philippe Steyer,Dominique Patureau +8 more
TL;DR: A new method combining chemical sequential extractions with 3D fluorescence spectroscopy was developed to provide a relevant SS characterisation to assess both OM bioaccessibility and complexity which govern SS biodegradability.

Management of pig manure to mitigate NO and yield-scaled N2O emissions in an irrigated Mediterranean crop
TL;DR: In this paper, the effect of different organic amendments derived from pig manure (control without N fertilization (C); liquid fraction of pig slurry (LFPS); pig urine with the nitrification inhibitor 3,4 dimethylpyrazolephosphate (DMPP) was evaluated on crop yields and yield-scaled N2O emissions were also evaluated.

Analysis of factors controlling soil organic matter levels in Great Plains grasslands
TL;DR: In this article, a model of soil organic matter (SOM) quantity and composition was used to simulate steady-state organic matter levels for 24 grassland locations in the U.S. Great Plains.

Terrestrial ecosystem production: A process model based on global satellite and surface data
Christopher S. Potter,James T. Randerson,Christopher B. Field,Pamela A. Matson,Peter M. Vitousek,Harold A. Mooney,Steven Klooster +6 more
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.
Climatic, edaphic, and biotic controls over storage and turnover of carbon in soils
David S. Schimel,Bobby H. Braswell,Elisabeth A. Holland,Rebecca McKeown,Dennis S. Ojima,Thomas H. Painter,William J. Parton,Alan R. Townsend +7 more
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.
Model estimates of CO2 emissions from soil in response to global warming
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.

The role of biology in the formation, stabilization and degradation of soil structure
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.
