Black carbon and organic matter stabilization in soil ...

Interaction with minerals is key to stabilization of organic matter in soils. Stabilization is commonly perceived to occur due to entrapment in pore spaces, encapsulation within aggregates or interaction with mineral surfaces. Typically only interactions between organic matter and minerals are considered in such a model. Here we demonstrate that black carbon may act very similar to minerals in ...

We determined and compared aggregate size distributions, SOC distribution in density fractions, and ligninderived phenols from aggregated soil samples at both eroding and depositional sites. The stabilization effect of aggregation was quantified by comparing mineralization from intact and crushed macroaggregates.

Soil aggregate stability - Wikipedia

Soil aggregate stability is a measure of the ability of soil aggregates to resist degradation when exposed to external forces such as water erosion and wind erosion, shrinking and swelling processes, and tillage (Papadopoulos, 2011; USDA, 2008).Soil aggregate stability is a measure of soil structure (Six et al., 2000a) and can be impacted by soil management (Six et al., 1998
