Abstract
The present disclosure is related to the development of improved fertilizer for precision and sustainable agriculture. A method was developed wherein efficient NPK nanocomposite for plant nutrition was synthesized in a single step using aerosol science and technology concepts. Further a formulation was prepared by addition of ZnO, TiO2 and other nanoparticles to the NPK nanocomposite. Also, an aerosol based foliar application technique was developed for the precise delivery of nanoparticles to the plants.
Claims17
A powder composition consisting of:
- (a) a plurality of nanocomposite particles each comprising a nanocomposite, wherein the nanocomposite particles have a particle size of about 25 nm to about 500 nm and are soluble in water, wherein each of the nanocomposite particles consists essentially of a combination of nitrogen, phosphorous, and potassium, and wherein each of the nanocomposite particles excludes chitosan, and
- (b) a plurality of metal oxide nanoparticles consisting of metal oxide.
