Dear Alireza Pirzad,

When we apply these fertilizer salts they are dissolved and hence no longer a nano-particle, instead it is an ion like any other ion absorbed from elsewhere like roots. In fact the concept beyond the nano-fertilizerz remains questioned and unless any particular difference with regular fertilizers is proved, it could be considered not more than a trade propaganda in my view.

Thank you very much for your reply.

Please give the references of this response for more detailes, if any.

Dear Alireza Pirzad,

As you know any salt becomes ionized after dissolving in water- this is a central dogma in physics/chemistry (http://en.wikipedia.org/wiki/Ion).

I think that the claim that such so called nano-fertilizers act different while they are essentially salts which ionize upon entering water should be proved and described by valid methods.
