Abstract

In forest soils, part of the soil organic matter occurs as water-soluble substances. They have an important role in pedogenesis related to their interference, with soil minerals (1) and to their metal-binding and transport properties. Different processes are involved including adsorption/desorption, complexation/dissociation and oxidation/reduction reactions. It is hypothesized that soluble organic substances in the soil solution also interfere with plant uptake of essential and non-essential cations (2) by affecting the mobility and speciation of cations.
