4. Nano Urea

5. Introduction
 The invention or development of “nano urea” has become topic,
subject and matter of discussion since May,2021.
 Nano urea is made up of two words 'nano’ and ‘urea’.
 The term ‘nano’ is adopted from ‘Greek’ word that means ‘dwarf’
and also “nano” means 10 -9 or one billionth part of a meter.
 Other word ‘urea’ which is a name of a product and fertilizer
which provides nitrogen to plants.
 Nano urea is a nano technology based liquid formulation of urea
which provides nitrogen to plants as an alternative to the
conventional urea.

6. Facts about Nano Urea
Invented By
Scientists of Indian Farmer Fertilizer Cooperative Limited (IFFCO) Sir
Ramesh Raliya and team.
 Invented At
It has been indigenously invented or developed at Nano Biotechnology
Research Centre, Kalol,Gujarat in line with Atmanirbhar Bharat and
Atmanirbhar Krishi.
 Invention Date
May, 2021. Commercial production of nano urea started since June,2021.

7. Price :- IFFCCO has priced Rs 240 per 500 ml of bottle.
Nitrogen Content :-It contains 40000 mg/l of nano particles of nitrogen .
 In a 500ml of bottle it contains 40000 ppm nitrogen which is equivalent to
impact of nitrogen nutrient provided by one bag of conventional urea.
 On the basis of weight it contains 4% of nano scale particles of nitrogen .
Recommended Dose:- IFFCO claims that 500 ml of a bottle is sufficient for
one acre. This is not a standard dose, because dose of nano urea depends upon
type of crops and nitrogen requirement of crops.

8. Specifications or Features of Nano Urea
 Nano urea developed by nanotechnology it contains nano scale particles of
urea (nitrogen ).
 It is available in liquid formulation, so it ts water soluble.
 Average physical size of nano urea particles is in the range of 10 – 50 nm
(30nm).
 Nano Urea contains 4 % nitrogen by weight in it’s nano liquid form.
 It contains 40000 mg/l or 40000 ppm nitrogen.
 Nitrogen present in nano urea effectively meets the crop’s nitrogen
requirement.
 Nano urea has better nitrogen use efficiency than conventional urea.

9. Significance of Nano Urea
 Improves plant nutrition:- It has been found effective and
efficient for plant nutrition which increases the production with improved
nutritional quality
 Environment friendly product:- It improves the soil by plant
residuals, didn’t caused underground water pollution like conventional
urea.
Increases farmer’s income :-It is a very cost effective farmers can
easily buy it. Also it increases the production of crops and also income of
farmers.

10. Benefit of Nano Urea

11. Benefits of Nano Urea
 Reduces input cost and increases income of farmer.
 Environment friendly product, completely safe for soil, air, water, birds,
microorganisms, animals and humans.
 Cheaper than conventional urea.
 Reduces nitrogen losses and increases soil fertility and productivity by
crop residuals .
 It can be applied on almost every crops.
 Use of nano urea decreases the subsidy amount which is provided by GOI
for conventional urea.
 Carrying and storage of nano urea are easy for farmers.

12.  Tool of sustainable agriculture.
 To test its efficacy, around 11,000 farmer’s field trials were undertaken on
more than 94 crops across India and results showed an average 8 per cent
increase in crop yields.
 Nano urea has been included in the government's Fertilizer Control Order
after the field trials were undertaken.
 The size of one nano urea liquid particle is 30 nano meter and compared to the
conventional granular urea it has about 10,000 times more surface area to
volume size.
 Due to the ultra-small size and surface properties, the nano urea liquid gets
absorbed by plants more effectively when sprayed on their leaves.

14. Application of Nano Urea
 Nano urea is available in the market as liquid formulation so it is
applied as foliar spray.
 Mix 2 to 4 ml of nano urea in one liter of water and spray on crop
leaves at active growth stages.
 For best results apply 2 foliar sprays.
 1st spray at active tillering / branching stage (30-35 days after
sowing/ transplanting).
 2nd spray 20-25 days after 1st spray or before flowering in the
crop.

15. Application Instruction
 Shake well the bottle before the use.
 Use flat fan or cut nozzles for spraying on the leaves.
 Spray during morning or evening hours, to avoiding dew.
 If rain occurs within 12 hours of the spray of nano urea, it is advised
to repeat the spray
 For better result nano urea should be used within 2 years from the
date of its manufacturing.
 Nano urea can easily be mixed with biostimulants , 100% water-
soluble fertilizers and agrochemicals.It is always advised to go for a
jar before mixing and spraying, for it’s compatibility.

16. How does Nano Urea Works
 When nano urea is sprayed on leaves, due to its very smaller size it
easily enters through stomata and other openings and is assimilated by
the plant cell.
 It is easily distributed through phloem from source to sink inside the
plant as per its needs .
 Unutilized nitrogen is stored in the plant vacuole and is slowly released
for proper growth and development of plants.

17. Note:
 Never stop application of nitrogen through DAP or complex
fertilizer at the basal dose/dressing
 Reduce only top-dressed urea applied in 2-3 splits.
 Number of spraying of nano urea can be increased.
 It is depending upon crops and it’s nitrogen requirement.

18. Limitations of Nano Urea
 Lack of production and availability of nano urea.
 Lack of standardization in formulation process.
 Lack of nano urea risk management system.
 High processing cost.
 It is not recommended as basal dose.
 Nano urea is cost effective but spraying cost in more than top dressing
/broadcasting cost.
 Mentality/perception of farmers also is a limitation for nano urea
because farmers who are used to of conventional fertilizers, definitely
avoid use of nano urea.

19. Prospect/Future and Conclusion
 We have known that all the benefits and limitations of nano urea.
 We have also known that use of nano urea increases production of crops and
income of farmers, which is main challenge in agriculture.
 It is also used as a tool for sustainable agriculture and do not causes any
harmful effects on environment..
 If the performance of nano urea will stable as it is now, definitely nano urea
will become boon and blessing for agriculture and famers.
 Nano urea will make “the age of science” to “the age of agricultural
science” by it’s contribution in agriculture.
 Nano urea will also bright the future of farmers and agriculture and also will
bring back the interest of peoples who have left the agriculture.
