Mineral–mineral and organo-mineral associations also contribute to stable aggregate formation, as organic matter may act as a binding agent between clay minerals (Denef et al. 2002). Permanently saturated wetland soils tend to be depleted in mineral oxides due to reduction and subsequent leaching losses (Mitsch and Gosselink 2015).
