Biogeochemistry of paddy soils

TL;DR: In paddy soils, the management-induced, microbially mediated redox processes control the dynamics of soil minerals and soil organic matter, which are strongly related to the microbial accessibility of C and N, but also of Fe as discussed by the authors.
Journal ArticleDOI
Stabilization of Soil Organic Matter: Association with Minerals or Chemical Recalcitrance?
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.
Journal Article
Review: organic matter removal from soils using hydrogen peroxide, sodium hypochlorite, and disodium peroxodisulfate
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 ).
Journal ArticleDOI
Biodegradation of forest floor organic matter bound to minerals via different binding mechanisms
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'.
Journal ArticleDOI
Poorly crystalline mineral phases protect organic matter in acid subsoil horizons
TL;DR: In this paper, the amount of hydroxyl ions released after exposure to NaF solution was used to establish a reactivity gradient spanning 12 subsoil horizons collected from 10 different locations.
