Organic acid behaviour in a calcareous soil: Sorption reactions and biodegradation rates.
Exudation of organic acids has been hypothesized to greatly improve the ability of plants to establish on nutrient poor soils such as those found in calcareous environments. An understanding of the behaviour of organic acids in these soils is crucial to the critical assessment of their potential capacity for nutrient mobilization. The aim of this study was therefore to study the sorption reactions
