Abiotic organic reactions that may be influenced by mineral surfaces include hydrolysis, elimination, substitution, redox, and polymerization. The effect of the surface may be either to promote (increase the rate of) or to inhibit (decrease the rate of) reactions that may occur in homogeneous solution. In addition, mineral surfaces may promote reactions that do not occur in homogenous solution by selectively concentrating molecules at the mineral surface... 

DOC transport through the soil and its concentration leaving a soil profile depends on abiotic sorption and desorption reactions with mineral surfaces. The tendency for organics to be strongly sorbed to soil particles through a variety of bonds can explain the order of magnitude drop in DOC fluxes in subsurface horizons (Neff and Asner, 2001 Ugolini et aL, 1977). For example, at the Harvard Forest, Massachusetts, Currie et al.
