Nano DAP

Context: After successfully checking urea imports by increasing its domestic production, the government is now said to be mulling a similar strategy for DAP which witnessed a 6 per cent rise in imports.

About Nano DAP

  • Nano DAP (Liquid) is indigenous and non-subsidised fertiliser with formulation containing Nitrogen (8.0% N w/v) and Phosphorus (16.0 % P2O5 w/v). 
  • IFFCO Nano DAP is an efficient source of available nitrogen (N) and phosphorus for all the crops and helps in correcting the Nitrogen & Phosphorus deficiencies in standing crops. 

Benefits

  • Nutrient use efficiency is more than 90 percent under optimum field conditions
  • It is cheaper than conventional DAP and is economical for the farmers. 
  • Beneficial as Seed Primer for Early Germination and Vigour, Enhances Crop Growth and Quality, Boosts Crop Yield.
  • Reduces pollution of soil, air and water due to excessive use of phosphatic fertilisers 
  • Bio-safe and Eco-friendly, fit for residue free agriculture.
  • Nano DAP (Liquid) has an advantage in terms of surface area to volume as its particle size is less than 100 Nanometre (nm). This unique property enables it to enter easily inside the seed surface or through stomata and other plant openings. 
  • Better spread ability and assimilation of Nano DAP inside the plant system leads to higher seed vigour, more chlorophyll, photosynthetic efficiency, better quality and increase in crop yields. 
  • Apart from this, Nano DAP through precision and targeted application fulfils the nutritional requirement of crops without harming the environment.
