COMPOSITIONS FOR SUSTAINED RELEASE OF AGRICULTURAL MACRONUTRIENTS AND PROCESS THEREOF

摘要

A macronutrient sustained release composition for a plant locus containing a nanocomposite wherein a nitrogen containing macronutrient compound adsorbed on the surface of hydroxyapatite phosphate nanoparticles is intercalated within the interlayer spacing of a nanoclay. The nanocomposite containing the adsorbed macronutrient compounds is slowly released in a sustained manner when contacted with an acidic soil.
