Introduction
Considering the increasing use of fine bubble technology in agriculture, this document has been
developed to establish standards in this area, with particular focus on promoting the germination and
growth of barley seeds.
The use of fine bubble technology in agriculture has been confirmed to benefit various types of
agricultural products and has attracted the interest of various countries. Application of the technology
to leafy vegetables in agriculture is already well-established, and this is being expanded to seed
germination and growth as well. Worldwide as well, standardization of fine bubble technology in the
field of agriculture is not only being spotlighted but is being conducted in practice at a rapid pace. The
technology is expected to blossom rapidly.
Fine bubble technology has been applied successfully not only in agriculture but also in the fields of
environmental science, food, marine products, medicine, etc. Wide-ranging progress in standardizing
the technology is being made in these fields. The achievement of standardization in various fields is
expected to result in increased worldwide recognition of fine bubble technology in the future.
