Use of sodium polytungstate in the granulo-densimetric fractionation of soil material
Eurasian Soil Science, 2011A solution of sodium polytungstate (SPT) is used as a heavy liquid in global soil studies. This reagent has found wide use because it is nontoxic, incombustible, well soluble, environmentally safe, and of low viscosity. There is a relatively simple and accessible method for its regeneration.

Abstract Physical protection is one of the most important ways for stabilization of organic carbon in soils, and in order to properly manage soils as a sink for carbon, it is necessary to know how much organic carbon a given soil could protect and to have information on the molecular composition of this protected organic matter in soil.

Organic matter features in the upper mineral horizons have been studied for four soils in the Subpolar Urals: humus-illuvial podbur (Entic Podzol), gleyic humus-illuvial podbur (Stagnic Entic Podzol), iron-illuvial podzol (Albic Podzol), and eluviated burozem (Leptic Cambisol). Organic matter pools have been separated by densimetric fractionation.

Soil organic matter (SOM) ageing may be measured by means of molecular signatures, ratios between organic compounds which inform us about the origin and/or the degree of biochemical evolution of (or microbial contribution to) specific groups of compounds: lipids, proteins, carbohydrates, etc.

The results of experimental studying of the organic matter status in soils using methods of granulodensimetric fractionation and the geochemistry of the stable carbon and nitrogen isotopes are presented. The organic and organomineral matter in chestnut soils representing a chronoseries—stages of natural changes in the vegetation with different carbon ...

The implementation of alternative cropping systems, including conservation agriculture (CA) and organic agriculture (ORG) in the La Cage experiment (France), and the organic waste products (OWP) application in the QualiAgro experiment (France) have led to an additional soil organic carbon (SOC) storage in ca. 20 years.

Ice mass fraction measurement in an ice slurry based on a densimetric method.
2007The ice slurry technology is today well known and one can expect its development in refrigerating systems, especially in district cooling networks. In this case, the cost of the refrigeration energy consumed by the end-user will depend on the measurement of the flow rate and the ice mass fraction.
