Patent / Technologies / Methodologies / System etc. (Upto Five) :

  1. Developed novel product of rock phosphate and waste mica enriched compost.This novel product has the potential to be adopted by the farmers and reduce the input cost and will provide an avenue to utilize low-grade RP.
  1. Developed novel technology to solubilize insoluble waste mica (K-mineral) through bio-intervention.This outclass product/technology has been reported first time by Dr. Biswas using waste mica inoculated with K solubilizing bacteria in the world.
  1. Synthesized polymer coated novel controlled release NP formulations using RP and mineral acids.This product of polymer coated novel controlled release NP formulation proved to be a potential carrier that supply N and P for a longer period.
  1. Developed novel P-fertilizer product of organic acid loaded NCPC with RP and phosphate solubilizing bacteria as slow release fertilizer to synchronize P release with crop demand and potentiality of this product as a promising alternate P source.
  1. Assessed innovative cost-effective nutrient management practices through value added organic manures prepared using crop residues and biodegradable wastes along with 50% NPK fertilizers for wide scale adoption by the farmers, thereby save 50% fertilizer.
