Nano fertilizers

Question 1

List some applications of nanotechnology

Answer 1

1. Defense and security
2. Textiles
3. Agriculture and food
4. Electronics
5. Energy storage

Question 2

Why use nano-fertilizers?

Answer 2

-Three-times increase in Nutrient Use
Efficiency (NUE)
-80-100 times less requirement to chemical
fertilizers
-10 times more stress tolerant by the crops
-Complete bio-source, so eco-friendly
-30% more nutrient mobilization by the
plants.
-17-54 % improvement in the crop yield.

Question 3

How do manufacture nano fertilizers?

Answer 3

The fertilizer was prepared by developing a methodology to use microbial enzymes for breakdown of the respective salts into nano-form.

Question 4

State major advantage of using nano-fertilizers over regular fertilizers?

Answer 4

nano fertilizers are economically cheap and are required in lesser amount.
Improvement in soil aggregation, moisture
retention and carbon build up.

Question 6

State a disadvantage of using nano-fertilizers.

Answer 6

The initial studies performed for nano materials
have caused serious health hazards and also
showed toxic effects, also when entered into
human body caused tissue damage reaching all
the vital organs.
