文摘

In the past several years, concern about the environmental fate of recalcitrant synthetic ligands (e.g.,EDTA) has increased. The used of new biodegradable chelating agents such as imidodisuccinic acid(IDHA) has been proposed as an alternative. However, its application as an iron ligand to correctiron chlorosis in agriculture has not yet been studied. Then the objective of this work is to determinethe fertilizer capacity of IDHA/Fe³⁺ using interaction assays with soils and soil materials and evaluatingFe nutrition of efficient and susceptible plants. Interaction of IDHA/Fe³⁺ with soil materials producesa reduction of the amount of soluble Fe. This is in good agreement with studies on the stability of theIDHA/Fe³⁺ chelate. In general, plant response to IDHA/Fe³⁺ in hydroponics is acceptable and betterthan that to EDTA/Fe³⁺. This good behavior seems to be related to the lower coordination of the ironin IDHA/Fe³⁺ with respect to EDTA/Fe³⁺.
