Soil organic matter interactions with trace elements

Part of the Developments in Plant and Soil Sciences book series (DPSS, volume 25)

Abstract

The availability of trace elements to plants is governed by a variety of reactions that include complexation with organic and inorganic ligands, ion exchange and adsorption, precipitation and dissolution of solids, and acid-base equilibria (90). A key role is often played by organic matter, both in enhancing availability to plants (65, 66, 113, 114) and in reducing toxicity effects of the free cation (20, 31, 62). Trace metals that would ordinarily convert to insoluble precipitates (as carbonates, sulfides, or hydroxides) at the pH’s found in many soils are undoubtedly maintained in solution through chelation.
