Very thoughtful post. I don't think , there is any compound nanomaterials developed so far , quite unlike compound chemical fertilizers.But , there are definite headway towards developing nanocomposites..

nano fertilizer found only

Dear Dr. Hudhaifa maan Al-Hamndi,

there are any some nanomaterials that can be used as chemical fertilizers.

Fertilizers containing nanomaterials have shown promising results for growth and yield.

Microfertilizers can be in the form of nanoparticles. Their advantage is that they gradually enter the plant from the surface of the grain and are used in small quantities. They should be used at concentrations an order of magnitude lower than their maximum permissible concentration. look at our work.
