Technical process for pro-
ducing clay nanoparticle-
polyester blended polymer
as binder for encapsulating
fertilizer
Nanoscale emulsions are
prepared by shearing aque-
ous dispersions of kaolin or
montmorillonite clay with
dodecylbenzenesulfonate
surfactants and are used to
encapsulate fertilizer

Preparation of polymeric
mixture from waste polysty-
rene foam and useful for
fertilizer adhesive or
capsules
Polystyrene foam is emulsi-
fied with a granulating
adhesive and sheared to
form nanoparticles for fer-
tilizer delivery

Manufacture of nano-olefin-
starch blend as fertilizer
packaging film adhesive or
granulating binder
A fertilizer nanocoating is
prepared by high-speed
shearing of a nanoscale
polymer blend cross-linked
with starch

Production technique of
coating cement for nano-
sulfonated lignin mixture
fertilizer
Nanoscale particles of a lig-
nosulfonate polymer are
generated by high-speed
grinding and then are used as
a coating agent to prepare a
slow-release composite
fertilizer

Method for manufacturing
fertilizer integument
cementing agent by using
papermaking black liquor
Lignosulfonate polymer
nanoparticles are prepared
by high-speed shearing and
sprayed on the surface of a
compound fertilizer to form
a nanoscale polymer coating
for slow-release applications

Methods to produce polymer
nanoparticles and formula-
tions of agricultural active
ingredients
A polyelectrolyte-
containing polymer and
agricultural active com-
pound are incorporated into
a nanoparticle (examples
given with sizes ranging
from 4 to 400 nm). The
active compound can be
released based on an exter-
nal stimulus
