2. Biodegradation Biological assimilation of organic carbon and subsequent generation of DOM plays an important role in controlling DOM dynamics in soils (Figure 1). , biosolids and livestock manures), the release of root exudates, and the lysis of microorganisms. , 1979). Considerable emphasis has focused on microorganisms because of their dual roles as decomposition agent and as a sink of labile organic C. Microbial assimilates represent an important source of DOM released from the forest floor, while microbial biomass serves as an important reservoir of DOM.
Adsorption of DOM onto soil minerals provides a model of this important process. Adsorption of DOM onto samples from Andisols, Inceptisols, and Entisols in batch experiments was compared in terms of the quantitative relationship Dissolved Organic Matter 27 between the soil properties and the adsorption behavior of DOM (Nambu and Yonebayashi, 2000). Andisols showed a particularly high efficiency of adsorption compared with those from other soils that contained a comparable amount of organic carbon.
2009; Stevenson, 1994). , 1996). , oxides, hydroxides, and oxyhydroxides of Al and Fe) that provide the majority of surface area for the sorption of DOM and other solutes in soil. Organic–mineral interactions range in strength from strong ligand exchange to weaker anion-exchange reactions (McBride, 1994). The bonding mechanisms of DOM onto the soil solid phase have already been elucidated by Gu et al. (1994) and Sollins et al. (1996). This includes bonding of negatively charged organics by ligand exchange especially in oxide-rich and allophanic soils, positively charged organics into negative surfaces by cation exchange, anion exchange onto subsoils and variably charged soils, and the less important mechanisms such as cation bridging, water bridging, hydrogen bonding, and van der Waals forces.
