What is liquid nano urea?

  • It is essentially urea in the form of a nanoparticle.
  • Urea is a chemical nitrogen fertiliser, white in colour, which artificially provides nitrogen, a major nutrient required by plants.
  • The product has been developed at IFFCO’s Nano Biotechnology Research Centre (NBRC) at Kalol.

Benefits of liquid nano urea:

  • This patented product is expected to not only substitute imported urea, but to also produce better results in farms.
  • Apart from reducing the country’s subsidy bill, it is aimed at reducing the unbalanced and indiscriminate use of conventional urea, increase crop productivity, and reduce soil, water, and air pollution.
  • While conventional urea has an efficiency of about 25 per cent, the efficiency of liquid nano urea can be as high as 85-90 per cent.

How does it work?

  • Conventional urea fails to have the desired impact on crops as it is often applied incorrectly, and the nitrogen in it is vaporised or lost as gas. A lot of nitrogen is also washed away during irrigation.
  • Liquid nano urea is sprayed directly on the leaves and gets absorbed by the plant.
  • Fertilisers in nano form provide a targeted supply of nutrients to crops, as they are absorbed by the stomata, pores found on the epidermis of leaves.
  • IFFCO advises that 2-4 ml of nano urea should be mixed a litre of water and sprayed on crop leaves at active growth stages.
  • Liquid nano urea has a shelf life of a year, and farmers need not be worried about “caking” when it comes in contact with moisture.
