â¢Organic acids can interact with Se in soil by adsorption, complexation and reduction processes.â¢Organic acids result in Se immobilization and mobilization in soil, thus the bioavailability.â¢FA-Se may be a latent source of available Se in soil and HA-Se is a sink of Se under some conditions.â¢The direct association mechanism between Se, and FAs and HAs can be visualized.
Organic Acids (OAs) are important components in the rhizosphere soil and influence Se bioavailability in soil. OAs have a bidirectional contrasting effect on Se bioavailability. Understanding the interaction of OAs with Se is essential to assessing Se bioavailability in soil and clarifying the role of OAs in controlling the behavior and fate of Se in soil. This review examines the mechanisms for the (im)mobilization of Se by OAs and discusses the practical implications of these mechanisms in relation to sequestration and bioavailability of Se in soil.
