Layered Double Hydroxides (LDHs) exhibit unique properties such as anion exchange capacity, acid lability, and high affinity to ubiquitous carbonate ion. In particular, acid lability and carbonate affinity make LDHs an excellent matrix to carry various agrochemicals because these properties facilitate complete and controlled release of the intercalated agrochemicals along with beneficial effects on many cultivated soils typically developing acidic characteristics. In this study, behaviors of LDHs in soils have been studied for application of LDHs to delivery of agrochemicals. Two types of LDHs, MgAl and CaFe types, were synthesized through coprecipitation route at room temperature. Their effects on the physico-chemical properties of soils and on mobilization of soil elements were examined in detail along with their fate in soils. It was shown that their frameworks were slowly degraded by acid solubilization to neutralize soil acidity as well as to release their components like Mg and Ca cations. This study shows that LDHs could be evolved into the excellent inorganic functional matrixes with high soil compatibility for delivery of various agrochemicals.
