Soil organic carbon stocks and related soil properties in a primary Picea abies (L.) Karst. volcanic-mountain forest

Our results indicate that in primary spruce-dominated forests on volcanic rocks, the regime of high-severity natural canopy disturbances may have positive effects on SOC accumulation in the mineral soil. The Alo/Feo ratio may be a potentially useful proxy for the relative degree of leaching and podzolization in these soils.
