The solution to many problems relate to the oxygen levels in the soil.

Why did you install Nano bubble?

In blueberry cultivation, the balance between roots and trees is critical.
The two keys to achieving this are to enable water management and to bring oxygen into the soil, which is easily absorbed by the trees.

I had long been searching for a way to establish a technology that would allow mass production cultivation using these two cultivation methods without incurring labor costs, and then I came across oxygen nanobubbles.

Why did you find oxygen nanobubbles effective?
Reasons
(1) Blueberry bearded roots are very fine and cultivate bacteria at the tip, absorbing nutrients and creating mycorrhizal fungi that take in oxygen and nutrients along with water. Oxygen in the soil creates good conditions for plants. One way to supply oxygen to the soil is to use a tiller. However, when planting blueberry trees, it is not possible to till the soil, and oxygen nanobubbles are an effective way to compensate for this.
(2) Because blueberries are not members of the grass family, they cannot absorb oxygen from the soil when soaked in water, causing root rot due to lack of oxygen. However, nanobubbles can eliminate the lack of oxygen. There are three sizes of oxygen molecules: large, medium, and small, and root growth depends on the combination of these sizes. Unlike apples and pears, blueberries do not store nutrients in the tree during the fruiting period, but after the fruiting period, photosynthesis occurs in the leaves and nutrients are stored in the tree and roots. Therefore, it is important how much nutrients are stored in the tree during the winter.

I decided to introduce the potted plant cultivation system I developed because I believe that when used in combination with oxygen nanobubbles, it will allow people to manage water more effectively.

Why do you need oxygen?

I knew early on that soil needs oxygen.
I tested with peat moss, rice husks, and cardboard, and when I placed a piece of cardboard cut lengthwise to 5 cm, the cardboard gave by far the best results.
This was thought to be due to its better air permeability.
However, there was a phenomenon that produced a very large number of insect larvae.

When the soil is filled with oxygen that the tree can easily absorb, the tree grows bigger. Trees grew 1.5 times longer than normal, bore larger fruit, and were found to be relatively larger.

Based on years of research, the root of the solution to many problems lies in the oxygen concentration in the soil.
I have concluded that ensuring that sufficient oxygen is available to the roots is the solution to a variety of problems.

 

How was the effect of Nano bubble?

・Normally, trees are stunted when they bear fruit. Flower buds do not grow easily, and new branches do not grow. However, trees grown in oxygen nanobubble water do not tire even after bearing fruit. Fertilizer is absorbed quickly because of good rooting.

・Oxygen nanobubble irrigation is very good for tree growth. The size of the fruit is different.

・New roots make the tree healthy. Old roots and trees are not so important. New ones produce more flower buds and taste better.

・Old roots do not absorb water well. Fertilizer goes up with the water. The bigger the tree, the wider it grows, but it also has more branches. It will not be able to absorb enough water.

・Roots do not only absorb water. They also naturally absorb oxygen from the roots. Trees grow by absorbing oxygen from the soil. Roots do not absorb carbon dioxide, but they do absorb oxygen. The more oxygen, the bigger the plants grow and the better the food tastes.

・Last year, blueberries irrigated with oxygen nano bubble irrigation were well received by customers for being sweet and delicious. Many customers enjoyed picking blueberries at tourist farms and took home their favorite varieties, but many also took home trees in the nanobubble zone.

 

How do you think about fertilizer absorption?

・Calcium is important to blueberries because an analysis of food ingredient lists showed that blueberries contain more calcium per gram than phosphorus or any other nutrient. However, calcium is the slowest-working of all foods. It takes a year to take effect. This is because it is slow to become absorbed.

・However, the calcium makes the fruit hard and does not fall off naturally after two years. We expected that if we added oxygen ultrafine bubbles, the calcium would take a year to work, regardless of fertilizer. Calcium and trace elements are important for good tree and root growth.

・Too much fertilizer will not produce flower buds. If phosphate is not excessive, the tree will grow with little or no fertilizer. If fertilizer is not applied properly, nitrogen and phosphoric acid will accumulate, clogging the roots and requiring replanting after eight years.
