Abstract: Soluble organic matter (OM) plays a central role in biogeochemical processes. Knowledge on the dynamics of OM at a molecular level is necessary to preserve soil health.
The formation of insoluble organo metallic complexes constitutes a major pathway for the stabilization of OM in soil. Thus, association of aluminum (Al) with OM rich in polysaccharides is largely responsible for aggregates stability.
Variations in fluorescence emission/excitation matrixes of soil solution from artificial soils (OECD guidelines) indicated the presence of Al–glucose (Glu) complexes. Biological degradation of Glu decreases, increasing the pool of stable OM in solution. Overall, Al–Glu complexation may affect soil biomass, metal mobilization and soil respiration. Similar processes control OM dynamics in soil.
