About Nano Urea Fertiliser

  • IFFCO created the liquid fertilizer known as nano urea. It serves as an alternative to regular urea.
  • It is urea in the shape of a nanoparticle, essentially.
  • An artificial source of nitrogen, a key nutrient needed by plants, urea is a chemical nitrogen fertilizer that is white in colour.
  • Its objective is to lessen farmers' reliance on urea in bags.
  • The 1985 Fertilizer Control Order (FCO): Is based on current regulations that, in the interim, permit the use of fertilisers based on information from just two crop seasons.
  • The Indian Council of Agricultural Research (ICAR) typically needed three seasons of independent evaluation before endorsing or rejecting a novel fertiliser for commercial usage, but in the case of nano urea, this was decreased to two.
  • Information on production: Approximately 440 million 500 ml bottles of nano urea will be made by FY25. This will be roughly 20 million tonnes of urea equivalent. The 9 million tonnes that India imports each year will be handled by it.
  • National Fertilizers Limited (NFL) and Rashtriya Chemicals and Fertilizers Limited (RCF), two Central Public Sector Undertakings (CPSUs), have signed a Non-Disclosure Agreement and a Memorandum of Understanding with IFFCO to transfer the technology of Nano Urea.
  • The goal of this is to increase domestic manufacturing of nano urea.
  • Data on imports: The nation produces about 26 million tonnes of urea domestically, whereas consumption is about 35 million tonnes. The shortfall is also filled by imports.
  • After switching to Nano Urea from traditional urea, the government will save about Rs 40,000 crore in foreign currency annually.
  • After 2023–2024, urea imports might not be necessary anymore.

How is the LNU better than the Conventional Urea?

  • Higher Efficiency: Liquid nano urea has an efficiency range of 85–90%, compared to the 25% efficiency of traditional urea.
  • Because it is frequently administered incorrectly and the nitrogen in it is wasted as gas or vapour, conventional urea does not have the desired effect on crops. During irrigation, a lot of nitrogen is also carried away.
  • Targeted Supply of Nutrients to Crops: The plant absorbs liquid nano urea that is sprayed directly on its leaves.
  • As they are absorbed by the stomata pores located on the epidermis of leaves, fertilizers in nano form deliver a focused supply of nutrients to crops.
  • Economical: One bag of urea can be successfully replaced by a bottle of nano urea.
  • Currently, there is no subsidy on the half-litre bottle of liquid nano urea, which costs Rs 240.
  • A farmer, on the other hand, spends about Rs 300 for a 50-kilogram bag of highly discounted urea.
  • Nano urea directly onto leaves causes it to be absorbed by the plant.

Potential advantages

  • Farmers do not need to worry about its "caking" when it comes into touch with moisture because it has a one-year shelf life.
  • Pricing: It is currently subsidy-free and available in half-litre bottles for Rs 240.
  • A farmer pays about Rs 300 for a 50 kg bag of highly discounted urea, in contrast.
  • Efficiency: Liquid nano urea has an efficiency range of 85–90%, compared to traditional urea's efficiency of roughly 25%.
  • Spraying liquid nano urea directly onto leaves causes it to be absorbed by the plant.
  • As they are absorbed by the stomata pores located on the epidermis of leaves, fertilizers in nano form deliver a focused supply of nutrients to crops.
  • Reduced subsidy Bill: It is intended to decrease the unbalanced and indiscriminate use of traditional urea and will lower the nation's subsidy bill.
  • Crop productivity is improved by the use of nano urea.
  • This is viewed as a fantastic substitute for artificial fertilizers because it encourages development while lowering environmental damage.
  • Additionally, nano-fertilizers shorten the length of the agricultural cycle and boost crop output.
  • Nanoparticles have special qualities that could be used to boost plant growth, including high absorption capacity, higher surface-to-volume ratios, and controlled-release kinetics to specific areas.

The drawbacks of nano-fertilizers

  • Lack of a risk management strategy for nano fertilizers

Nano fertilizers are not produced in sufficient amounts or are not readily available. This restricts the use of nano-fertilizers as a source of plant nutrients on a larger scale.

  • The expensive price of nano fertilizers

The procedure of formulation is not standardized. Due to the diverse pedoclimatic circumstances, the same nanomaterial produces various effect

Way Ahead

  • Guidelines for the establishment of entrepreneurs for the drone spraying of liquid fertilizers have also been released by the department.
  • Numerous initiatives are used to promote the use of nano urea, including awareness campaigns, webinars, nukkad nataks, field demonstrations, Kisan sammelans, and regional language movies.
  • The nation's first liquid nano urea facility was recently opened by the Prime Minister at Katol.

World bank logistic performance index 2023

India is now ranked 38th out of 139 nations in the Logistic Performance Index (LPI) 2023 of the World Bank. From its previous rankings of 44th in 2018 and 54th in 2014, this is a notable improvement. Earlier, the Logistics Ease Across Different States (LEADS) Report 2022 was published by the Ministry of Commerce and Industry. About Logi
