【Hyogo】Foliar spraying of NB increases the percentage of excellent Japanese Yam by 20%!
Kobe City, Hyogo Prefecture
Mr. Tatsushi Ueda
Why did you introduce Nano Bubbles?
He knew Kakuichi because he had inquired about them when he was looking for an agricultural equipment warehouse.
Around 2019, one of his regular customers asked him, “I heard a company I know is looking to monitor Nano Bubble generators for agriculture, are you interested?”
To which he replied, “I would love to hear about it,” and Kakuichi came to him.
How do you use Nano Bubbles?
He uses a circulating Nano Bubble generator that runs on a 100V power supply to create Nano Bubble water by circulating it for 40 minutes in a 300L lorry tank on a light truck.
He uses it as dilution water for spraying liquid fertilizer and fungicides on leaves.
How were the effects of Nano Bubbles?
Just two applications of Nano Bubbles for foliar spraying increased the number of leaves on the Japanese Yam.
When typhoons hit, he would worry so much about whether the weight of the leaves would cause them to fall over easily.

He waited with bated breath to see how this effect would affect the harvest.
The result was a surprise: a significant increase in the rate of superior Japanese Yam.
In the control area, the Japanese Yam was wildly out of shape, had an uneven size, and some of the seed yams were still in the same state.
In the NB-treated area, on the other hand, the Japanese Yam were uniform in size, round in shape, and had a large amount of roots.
This difference was at a level that was noticed by the part-timers assisting in the harvest.
As a result, the rate of superior products in the control area was about 30%, while the rate of superior products in the NB-treated area exceeded 50%.
Advisors from agricultural material manufacturers who were present at the harvest were also surprised by these results.
(1) The compatibility of Nano Bubble and fertilizers was good.
(2) The improved rooting, which allowed the seedlings to withstand the summer heat and receive nutrients more evenly.
He thought that these two factors were the main reasons for the change.
Mr. Ueda believes that the penetration and absorption of organic fertilizer components may have been enhanced by the penetration-enhancing effect of the Nano Bubbles.
Reproducibility tests were conducted the following year with similar results.
How do you manage fertilizer and irrigation in using Nano Bubbles?
The Nano Bubble treatment clearly increases the amount of roots, so if we increase the amount of fertilizer applied, we will be able to harvest even larger Japanese yam.
However, since the most demanded size of Japanese Yam is about 1.1 lbs, the same management methods are used as before to prevent them from growing too large.
What kind of difficulties do you face in growing Japanese Yam?
He is a farmer and an interior decorator.
He enjoys both jobs so much that he does not feel it is a hardship, but there were times when he could not take care of Japanese yam because his interior design business took up so much of his time.
There was even a year when the rate of superior products was the worst at 8%.
About the future
Mr. Ueda currently grows Japanese Yam in the open and asparagus in greenhouses, but he is always eager to gather information on profitable crops.
Kakuichi regularly introduces examples of Nano Bubble use by other farmers on its website and official line, so we would like to consult with them again when we start a new challenge and make the most of Nano Bubbles.
