Ultrafine bubble water mitigates plant growth in damaged soil

Water containing ultrafine/nano bubbles (UFBs) promoted the growth of tomato (Solanum lycopersicum) in soil damaged by cultivation of tomato in the previous year or bacterial wilt-like disease and also promoted the growth of lettuce (Lactuca sativa) when lettuce was grown in the soil damaged by repeated cultivation of lettuce. On the other hand, UFB supply did not affect plant growth in rock wool or healthy soil. Furthermore, the growth of lettuce was not affected by UFB water treatment in the soil damaged by the cultivation of tomato. UFB water partly suppressed the growth of the pathogen of bacteria wilt disease, Ralstonia solanacearum in vitro. These data suggest that UFB water is effective to recover the plant growth from soil damage.

Automated summary

Water containing ultrafine/nano bubbles (UFBs) can promote plant growth in soil damaged by previous cultivation, but does not affect plant growth in rock wool or healthy soil. Additionally, UFB water treatment can partly suppress the growth of the pathogen of bacteria wilt disease.
