Biodegradability of soluble organic matter in maize-cropped soils
TLDR
In this article, the authors evaluated the quantity and biodegradability of soluble organic matter in soil under monoculture maize or maize−soybean rotation, and different amendments: manure, inorganic fertilizer, or no amendment.About:

SOM fractionation methods: Relevance to functional pools and to stabilization mechanisms
Margit von Lützow,Ingrid Kögel-Knabner,Klemens Ekschmitt,Heinz Flessa,Georg Guggenberger,Egbert Matzner,Bernd Marschner +6 more
TL;DR: In this article, the SOM fractions obtained with such operational fractionation procedures are described in terms of their pool sizes, chemical properties, and turnover rates, and the main objective is to evaluate these operationally defined fractions with respect to their suitability to describe functional SOM pools that could be used to parameterize SOM turnover models.
Journal ArticleDOI
Biodegradation of soil-derived dissolved organic matter as related to its properties
TL;DR: In this paper, the extent and rate of DOM biodegradation from less humified organic material (straw, litter and fermentation layers of forest floors) were quantified by CO 2 evolution.

Microaggregates in soils
Kai Uwe Totsche,Wulf Amelung,Martin H. Gerzabek,Georg Guggenberger,Erwin Klumpp,Claudia Knief,Eva Lehndorff,Robert Mikutta,Stephan Peth,Alexander Prechtel,Nadja Ray,Ingrid Kögel-Knabner +11 more
TL;DR: In this paper, a harmonized concept for aggregates in soils is proposed that explicitly considers the structure and build-up of microaggregates and the role of organo-mineral associations.

The Depth Distribution of Soil Organic Carbon in Relation to Land Use and Management and the Potential of Carbon Sequestration in Subsoil Horizons
Klaus Lorenz,Rattan Lal +1 more
TL;DR: In this paper, the subsoil carbon (C) sequestration may be achieved by higher inputs of fairly stable organic matter to deeper soil horizons, which can be achieved directly by selecting plants/cultivars with deeper and thicker root systems that are high in chemical recalcitrant compounds like suberin.
Journal ArticleDOI
Soil organic matter in soil depth profiles: Distinct carbon preferences of microbial groups during carbon transformation
C. Kramer,Gerd Gleixner +1 more
TL;DR: In this paper, the carbon sources of soil microbial communities vary with soil depth, and the isotopic signature of bulk SOM and PLFA from C4 cultivated soil decreases with increasing soil depth (−23.7

Organic matter and water-stable aggregates in soils
Judith. Tisdall,J.M. Oades +1 more
TL;DR: In this article, the effectiveness of various binding agents at different stages in the structural organization of aggregates is described and forms the basis of a model which illustrates the architecture of an aggregate.
Journal ArticleDOI
Controls on the dynamics of dissolved organic matter in soils: a review.
TL;DR: In this article, the authors summarize the recent literature about controls on dissolved organic matter (DOM) concentrations and fluxes in so-called "soil degraded organic matter" (SOCOM).
Journal ArticleDOI
Physical fractionation of soil and structural and functional complexity in organic matter turnover
TL;DR: In this paper, the authors link the methods of fractionation to concepts of turnover by defining levels of structural and functional complexity that refer to experimentally verifiable pools of organic matter in the soil.

Alkaline persulfate oxidation for determining total nitrogen in microbial biomass extracts
TL;DR: In this article, the persulfate oxidation method (TPN) was used for determination of soil microbial biomass N in 0.5 M K₂SO₄ extracts.
