Interpretive Summary:

Technical Abstract: Phenolic acids are released into soils by plants as decomposition metabolites and, in some plants, as root exudates or leaf leachates. These chemicals are involved in several soil processes, including the formation of humus, nutrient availability, dissolution of minerals, and allelopathy. Their availability for these processes is controlled by sorption and degradation interactions. In order to understand allelopathic effects of phenolic acids, we need to understand their behavior in soil. The first step to a better understanding of soil behavior is to characterize the sorption-desorption interactions of these compounds in soil. In this paper, the characterization of sorption-desorption of the phenolic acids p- coumaric acid, ferulic acid, vanillic acid, p-hydroxybenzoic acid, and veratric acid as a function of soil properties in relationship to the reactivities of these compounds with soil components will be examined.
