TL;DR: An overview of the current knowledge on mineral-organic associations can be found in this article, where the authors identify key questions and future research needs, as well as a survey of the existing research work.

TL;DR: In this article, the authors analyzed pool size and isotopic composition (14C, 13C) of mineral-protected and recalcitrant organic carbon (OC) in 12 subsurface horizons from 10 acidic forest soils, showing that stabilization of OM by interaction with poorly crystalline minerals and polymeric metal species is the most important mechanism for preservation of OM in these acid subsoil horizons.

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.

TL;DR: In this article, the authors compared the performance of three most commonly used reagents for organic matter removal: hydrogen peroxide (H 2 O 2 ), sodium hypochlorite (NaOCI) and disodium peroxodisulfate (Na 2 S 2 O 8 ).

TL;DR: In this paper, the authors studied the biodegradation of OM bound to goethite (α-FeOOH), pyrophyllite, and vermiculite via specific mechanisms as estimated from OC uptake in different background electrolytes and operationally defined as 'ligand exchange', 'Ca2+ bridging', and 'van der Waals forces'.
