Plant roots need oxygen as much as water. In warm climates and heavy soils, irrigation water often carries little dissolved oxygen, and roots suffer. Water enriched with micro and nano bubbles delivers more oxygen to the root zone through the drip and sprinkler lines farmers already use.
+14%strawberry yield with oxygen nanobubble irrigation in the Netherlands
−74%Pythium counts in the same trial
+16–19%greenhouse tomato yield in a Chinese study
Where it is used- Greenhouse strawberries and tomatoes in the Netherlands and Spain
- Greenhouse vegetables in Zhengzhou, China
- Fruit orchards and cherries in Chile
- Suited to drip-irrigated vegetable and fruit farms in India
How it works hereRoot respiration powers nutrient uptake. When the root zone runs short of oxygen, growth slows and anaerobic pathogens such as Pythium spread.
Nanobubble water carries far more dissolved oxygen than normal irrigation water: in the Dutch strawberry trial, treated water averaged about 30 mg/L against 7–9 mg/L.
Because nano bubbles stay suspended, the oxygen survives the journey through pipes and drippers to the roots.
What the research shows
Evidence from the field
Field / institute trialOxygen nanobubble irrigation for strawberries
Delphy Research Institute, Netherlands · 2020
- Treated irrigation water held about 30 mg/L oxygen versus 7–9 mg/L in the control
- Yield was 14% higher
- Pythium counts were 74% lower, with healthier roots and less Phytophthora
Source: Fresh Fruit Portal: nanobubbles increase strawberry yields by 14% ↗Peer-reviewed studyNano-bubble irrigation for greenhouse tomatoes
Zhengzhou, China · Agronomy, 2023
- Compared nano-bubble irrigation with conventional irrigation in greenhouse tomatoes
- Yield increased by 16.4% and 18.9% in the two treatments
- The study also measured changes in greenhouse gas emissions from the soil

- Install the generator between the water source or tank and the irrigation pump line
- Run on air for general irrigation, or with oxygen for high-value greenhouse crops
- The 1.5 HP or 4 HP model covers most farm drip systems; flow is matched to the system during the site visit
- Keep filters clean so drippers stay clear
Good to know: Most published irrigation trials are on greenhouse crops. Open-field results depend on soil type, climate and irrigation method.
