At the end of June, the winter onion harvest began in the Southern Ukraine region. Despite drought conditions during sowing and growing, light rains in late spring and early summer helped preserve the crop.
According to Alla Stoyanova, head of the "Stoyanov A.A." farming enterprise, several Italian hybrid varieties, Balstar and Divina Star, were planted last autumn. This season, the farm also trialed a new Japanese nanobubble technology to improve irrigation efficiency and crop performance.
"We signed a cooperation memorandum with the Japanese company Kakuichi. Through this partnership, we received equipment that generates nanobubbles, enriching irrigation water with oxygen," said Stoyanova. "Each cubic centimeter of water contains around 3 million nanobubbles. This significantly improves plant development, especially in our hot and dry Bessarabian steppes, where oxygen is lacking in the root zone."
The results so far are encouraging: onions irrigated with nanobubble-treated water showed better growth and higher yield potential compared to conventional methods. In addition to benefiting plant development, the technology also has a positive impact on soil quality by supporting beneficial soil microbiota.
Stoyanova noted that the technology is still in the testing phase, and scientists are currently analyzing data to assess yield differences and long-term effects on soil conditions. The farm hopes nanobubble irrigation will become a sustainable solution for improving soil and crop productivity in challenging climatic conditions.
