Generation of Nano Bubbles Using Cavitation Technique and Monitoring of Strawberry Growth by the Generated Nano Bubbles

Summary

In this study, nano bubbles (NBs) of around 100 nm size were generated by using GoodSam-NB generator (made by S company) which utilizes cavitation technique. The generated NBs were directly applied to the strawberry cultivation process to monitor the productivity of strawberry. When the aqueous nutrient solution with NBs was supplied to the strawberry culture medium, it had a slightly higher initial concentration of dissolved oxygen (DO) compared to the nutrient solution prepared with ordinary groundwater at a concentration of about 9 mg/L and did not decrease over time. In other words, NBs helped to supply DO to support the development of roots in the early stage of strawberry’s growth, thereby promoting the overall growth of strawberries. After feeding the NBs nutrient solution, the nitr
