Short summary

We studied the contribution of litter-derived carbon (C) in the formation of subsoil organic matter (OM). Soil core sampling, ¹³C field labeling, density fractionation, and water extractions were used to track its contribution to different functional OM fractions down to the deep subsoil. We show that while migrating down the soil profile, OM undergoes a sequence of repeated sorption, microbial processing, and desorption. However, the contribution of litter-derived C to subsoil OM is small.
