Description :
This study aims to review and integrate the determining factors and mechanisms of soil organic matter (SOM) stabilisation in andic compared with other (non-andic) soil types. The AA. have reviewed recent literature regarding the nature of SOM and its stabilisation processes in the top- and sub-soil to address and discuss the interaction between the SOM and the mineral phase. The carbon (C) storage capacity by the metal-humus-complex formation of volcanic soils is also evaluated. The most important stabilisation processes are related to the incorporation and decomposition of microbial-derived C along with the changing C storage capacity with increasing soil development. The priming and destabilisation of adsorbed SOM are crucial mechanisms influencing the soil C sequestration in subsoils. Al and Fe oxides are the main stabilising agents in andic soils. The influence of climate, mineralogy and soil disturbances on the SOM storage capacity of andic soils also require further attention.
