The sorption of dissolved organic matter (DOM) depends on its interaction with the soil matrix. In hydromorphic podzols, DOM reacts mainly with aluminium (Al), which is responsible for the formation of the Bh-horizon in the subsoil. In this work, we investigated whether the retention of DOM in the soil during the podzolization process is selective in relation to the molecular composition of DOM. A column experiment was conducted to study the selective retention of sorption and desorption processes under controlled conditions. Materials used in the column experiment were representative for Brazilian coastal podzols under tropical rainforest. Materials were collected from this tropical coastal podzol ecosystem, and included soil from E- and Bh-horizons, and DOM from a stream (Stream), peat water (Peat), litter (Litter) and charred litter (Char). To evaluate selective retention of DOM, both the initial DOM and its leachates were analyzed by Fourier transform infrared spectra absorption (FTIR) and pyrolysis gas-chromatography/mass spectrometry (Py-GC/MS). The results showed preferential retention of DOM associated with biopolymers for soil columns with E-horizon material (E), E with Al nitrate (E-n), E with kaolinite (E-k) and E with gibbsite (E-h), except for Char. The composition of leachates after percolation through B horizon columns was mainly determined by desorption, and had a relatively large contribution from phenolic and carboxylic groups associated with Al and low molecular weight aromatic and N-containing pyrolysis products, while products from macromolecular materials such as cellulose were selectively retained in the columns for all DOM types. DOM from the Stream (taken during the rainy season) resembled that of desorbed OM from the B columns, reinforcing substantial desorption in the field as well. Our results suggest that sorption and desorption of OM in the hydromorphic Bh-horizon is continuous and that the selectivity of sorption is dependent on DOM source MenosThe sorption of dissolved organic matter (DOM) depends on its interaction with the soil matrix.
