1. The document discusses nanotechnology applications in fertilizers including encapsulation of nutrients in nanoparticles, use of nano-sized nutrients, and slow/targeted delivery of nutrients. 2. Key benefits of nan fertilizers are increased nutrient efficiency, dispersion of insoluble nutrients, constant nutrient release, and delivery of nutrients where needed. 3. Potential disadvantages include toxicity issues if nanoparticles enter the human body and environmental impacts that require further study.

of fertilizer
2
Increase
uptake
from soil in
crop

7. SLOW DELIVERY
 It release of fertilizer
in a constant
concentric manner.
 This are the gradient
for the slow delivery.

8. leIt delivery
at where
it is
needed
Some
nanoparticles
are available
for delivery
Eg. Silver, zinc
oxide

TARGETED DELIVERY

9. ADVANTAGE AND DISADVANTAGE
ADVANTAGE
Nano coating- reduce
cost
Increase productivity
Improvement in soil
aggregation
High yield than conventional DISADVANTAGE
Poses problem toward
environment
Nanoparticle are toxic
when entering human body
