Method for cultivating high-
quality high-functionality
fruit and vegetables
Selenium, calcium hydrox-
ide, and iron oxide
nanoparticles added to seed-

Gardening fertilizer
containing stevia extract and
minerals and preparation
method thereof by using
fermented stevia extract as
penetration accelerator for
functional material
Stevia (a sweet herb and
sugar substitute) is mixed
with nanoparticles of Se,
organo-Ca, rare-earth ele-
ments, and chitosan and pul-
verized to a size of 75-95 nm.
When used as a seed-coating
agent, improved root growth
was noted. Cross-listed in

Special fertilizer for cotton
base fertilizer
Completely fermented
organic fertilizer is mixed
with nano-iron ore tailing
powder. Nano-iron powder
acts as an insecticide, slows

Complete plant growth
medium comprised of natu-
rally occurring zeolite coated
with nanophase iron oxide
and dosed with nutrients
A zeolite host covered with
iron oxide nanoparticles (10-
50 nm diameter) can be
loaded with plant nutrients
and has increased fertilizer
use efficiency. Other benefits
include water retention, odor
suppression, and pest resis-
tance. Cross-listed with Cat-
egory 3 zeolites
