Densimetric Fractionation of Soil Organo-Mineral Complexes
Journal of Soil Science, 1975Summary A rapid, simple, and precise density fractionation of soil mineral‐organic complexes, suitable for routine work, is described. Special features of the method are: low sample weight, use of glass‐fibre paper to collect the lighter fractions, and use of a modified Walkley‐Black procedure to determine the carbon content of the ...

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.

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.

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.
