A macronutrient sustained release composition for a plant locus having nitrogen containing macronutrient compound adsorbed on the surface of hydroxyapatite phosphate nanoparticles, and a process for preparation thereof. The macronutrient adsorbed hydroxyapatite phosphate nanoparticles 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 nanoparticles 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.
A macronutrient sustained release composition comprising:
The composition of 1 wherein said macronutrient compound is urea.
The composition of 1 wherein the plant locus is a low pH crop.
A process for preparing a macronutrient sustained release composition comprising;
A method of macronutrient sustained release to a plant locus comprising:
