Humic acid Nanometer soil amendment
and its application in field
crops
Si nanoparticles mixed with
humic acid are pulverized
down to the nanoscale. The
nanosilica lends a water- and
mineral-adsorbing quality to
the composite. Reduced fer-
tilizer use and improved
yields are claimed. Cross-
listed in Category 2 Si

Production of nanometer
humic acids-polymer com-
posite and its application in
agriculture
Nanoscale particles of humic
acid and calcium silicate are
prepared by high shear and
mixed with a starch-acrylo-
nitrile copolymer. The com-
posite can be used as a seed-
coating agent and a fertilizer-
coating agent for controlled
release. Could potentially be
cross-listed under Category 3

Rare earths Method for manufacturing
nanoscale compound fertil-
izers by using nanomaterial
and MgO-rich seawater
Kaolin, montmorillonite, and
rare-earth nanoparticles
mixed with MgO, N, P, and K
