TL;DR: In this article, a new generation of experiments and soil carbon models were proposed to predict the SOM response to global warming, and they showed that molecular structure alone alone does not control SOM stability.

TL;DR: A molecular-level assessment of the physical organization and chemical complexity of biomass-derived chars and, specifically, that of aromatic carbon in char structures suggests the existence of four distinct categories of char consisting of a unique mixture of chemical phases and physical states.

TL;DR: It is argued that the available evidence does not support the formation of large-molecular-size and persistent ‘humic substances’ in soils, and instead soil organic matter is a continuum of progressively decomposing organic compounds.

TL;DR: In this article, the authors summarize progress with respect to different approaches to isolate, extract, and quantify organomineral compounds from soils, types of mineral surfaces and associated interactions, the distribution and function of soil biota at organo-mineral surfaces, and factors controlling the turnover of organic matter (OM) in organic matter associations from temperate soils.

TL;DR: In this paper, the authors propose a structure for organo-mineral associations in soils based on recent insights concerning the molecular structure of soil organic matter (SOM), and on extensive published evidence from empirical studies of organomineral interfaces.
