Fine bubble technology — Agricultural applications — Part 4: Test method for evaluating the number concentration of ultrafine bubbles (UFB) achieving the promotion of barley seed germination
This document specifies a method to assess the ultrafine bubble (UFB) number concentration in order to find whether the number concentration of UFB generated by users is in the adequate range for promoting the barley seed germination stably irrespective of seed variety conforming to ISO 23016-2 and ISO/TR 23016-3.
