20110296885 | COMPOSITIONS FOR SUSTAINED RELEASE OF AGRICULTURAL MACRONUTRIENTS AND PROCESS THEREOF - A macronutrient sustained release composition for a plant locus containing a nanocomposite wherein a nitrogen containing macronutrient compound adsorbed on the surface of hydroxy apatite 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. | 12-08-2011 |

20110296887 | CELLULOSE BASED SUSTAINED RELEASE MACRONUTRIENT COMPOSITION FOR FERTILIZER APPLICATION - 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. | 12-08-2011 |
