【Hiroshima】Dramatic labor savings! Automatic irrigation without going to the field!
Higashi-Hiroshima City, Hiroshima Prefecture
Mr. Hirofumi Doi
He is a former JA employee who has been growing rice for generations.
Eight years ago, he started growing tomatoes in a greenhouse.
He started growing CF Chika (mini-tomatoes) in greenhouses 8 years ago.
The cultivation area is about 300 square meters.
He sells directly (mainly by word-of-mouth phone orders from repeat customers) and at a nearby farmers’ market.
His tomatoes have a reputation for being very sweet and tasty, and he often has to decline orders because he is out of stock.
Why did you introduce Nano Bubbles?
After I became the representative, I expanded the area of rice cultivation to 10 ha and also started open field cultivation of white onion and green pepper, so I was feeling quite burdened with the time and effort of manual irrigation for greenhouse cultivation of tomatoes and the time I had to spend in the field.
At that time, I purchased an agricultural warehouse from Kakuichi, and Kakuichi told me that they were looking for monitors for a solar-powered open-air type of Nano Bubble Generator.
How was the effect of the Nano Bubble Generator?
I honestly do not notice any change in cultivation or taste, but thanks to automatic irrigation on a timer using sunlight, even though there is no power source, I do not have to stay in the field and can do other work in that amount of time.
It is only 20 to 30 minutes a day, but over the course of a season, it is a significant labor savings.
Since the yield and sugar content are maintained with this system, I did not hesitate to purchase it after the monitoring period was over.
I can’t let it go now (laughs).
About the future
This area in Hiroshima is particularly cold in winter.
In winter, we drain and manage the water as advised by the sales person, but I think it would be easier if there were specifications with freeze protection as standard equipment, so please consider this for future improvement.
I would like to use it for a long time.
Requests to Kakuichi
When I was a monitor, I had some trouble because the battery ran out or stopped working due to poor contact.
I appreciate the quick response and I am responsible for the management of the system, but it is also true that it is difficult to notice any problems because the system is unattended during irrigation and I rely on the equipment.
I hope that you will develop a sturdy and safe device and consider having a system that notifies you when an error occurs so that you can use the device with even greater peace of mind.
