listed in Category 2 as an
additive to a bulk fertilizer
Method for preparing nano-
scale Se-rich green tea with
antitumor activity
A foliar fertilizer of nano-
scale selenium particles (less
than 400 nm), prepared by
milling, led to greater sele-
nium content in green tea.
Could potentially be cross-
listed in Category 2 as an
additive to a bulk fertilizer

Nanoselenium-amino acid
foliar fertilizer and prepara-
tion method of the same
A nanoselenium-amino acid
conjugate foliar fertilizer is
prepared to achieve improved
crop selenium absorption
rate. Method describes the
preparation of amino acid-
coated selenium
nanoparticles (average diam-
eter 38 nm)

Method for improving qual-
ity of blueberry fresh fruit by
using biological selenium
nanometer fertilizer
Nanoselenium (size not
specified) added to soil three
to five times throughout
blueberry growth cycle
results in higher quality and a
longer storage period
