A CELLULOSE BASED SUSTAINED RELEASE MACRONUTRIENT COMPOSITION FOR FERTILIZER APPLICATION.

摘要

A macronutrient sustained release composition for a plant locus having nitrogen containing macronutrient compound adsorbed on the surface of hydroxyapatite phosphate nanopartides, and a process for preparation thereof. The macronutrient adsorbed hydroxyapatite phosphate nanopartides are encapsulated within cavities present in wood such that the biodegradation of the wood releases the adsorbed macronutrient compounds in a slow and sustained manner to the soil. Further, the macronutrient particles are encapsulated within the cell cavities of wood and wood is coated with cellulose modified hydroxyapatite phosphate nanopartides such that the rupture of the nanocoating initiates the nitrogen release followed by the biodegradation of the wood releases the rest of the adsorbed macronutrient compounds in a slow and sustained manner to the soil.
