Recent trials in 2020, conducted by Delphy Research Institute in the Netherlands, in conjunction with Moleaer, to examine the effects that oxygen nanobubble enrichment of irrigation had on strawberry cultivation.

In the test, Delphy was able to isolate two cohorts differentiated by one variable: dissolved oxygen (DO) and high concentrations of nanobubbles in the water. In the study, a control group held DO steady between a typical 7 and 9 mg/L, while the nanobubble treated water was brought to an average DO concentration of 30mg / L.

Plants irrigated with Oxygen Nanobubbles had a 14% yield increase compared to untreated plants

At the trial conclusion, plants irrigated with oxygen nanobubbles had a 14% yield increase compared to untreated plants (8.2Kg vs 7.2Kg). Pythium counts were 74% lower in samples treated vs. the untreated control group. Plants irrigated with oxygen nanobubbles also had healthier root mass and lower instances of disease (Phytophthora).

Bart Jongenelen from Delphy said: “We had followed previous results with nanobubbles in other crops with interest and as I learned more about the properties of the nanobubbles I have to say that I became more and more interested. The theory behind it is that oxygen plays an important role both in the nutrient uptake of roots and in the biology in the root environment. For these trials, we chose to focus on yield and to follow the root development with visual inspections. Clear differences emerged from this. For example, the total production was almost 1kg higher with the nanobubble treatment.”

Nanobubble Systems Australia and New Zealand BDM, Leon Power: “It is very exciting to see that the effects on crops, where nanobubbles have been getting great results; Leafy greens, capsicums, tomatoes, and blueberries are now being replicated in strawberries as well.”

The Nanobubble Generator serves a two purposes:

1. Nanobubbles transfer oxygen extremely efficiently into water, and allows us to maintain very high saturation levels, up to +400% saturation, with minimal loss. This enables us to deliver significantly more oxygen into the root zone and promote healthy root development.

2. The oxidative properties of the oxygen nanobubbles break down algae and suppress pathogens, effectively improving the water quality and maintaining a more hygienic irrigation system.”

Moleaer’s nanobubble technology has proven its effectiveness in over 450 installations in 32 different countries, in a wide range of cultivation methods.

Benefits of Nanobubbles may include:

  • Increased water clarity

  • Reduced Pythium levels

  • Algae reduction in source water

  • Increased water retention in the soil

  • Increased nutrient uptake

  • Improved vegetative growth

  • Increase in fruit size and yield

  • Increased chlorophyll content

  • Healthier root development
