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.

TL;DR: In this paper, the authors conducted a study to determine the effects of long-term addition of organic and inorganic fertiliser amendments at low rates on soil chemical and biological properties.

TL;DR: In this article, the controlling factors for DOM biodegradability can be divided into three groups, namely, intrinsic DOM quality parameters, soil and solution parameters and external factors, and the major obstacle for a better understanding of the controlled properties of DOM is the lack of a standardised methodology or at least systematic comparisons between the large number of methods used to assess DOM bioregradability.

TL;DR: In this article, the authors evaluate how relevant recalcitrance is for the long-term stabilization of soil organic matter (SOM) or its fractions, based on a critical overview of available methods and on results from a cooperative research program.

TL;DR: In this paper, the authors investigated the effect of 14 C-glucose addition on the mineralisation of charred maize and rye residues and oak wood (thermally altered at 800 C).
