Oxygen Nanobubbles in Agriculture

Tests showed stronger root development and higher crop yields with oxygen nanobubble irrigation, including ~3× root density in Korean melon after two weeks.

CASE 01

Early Root Establishment & Density

In a Korean melon trial, root development and early establishment improved; root density was ~3× the groundwater comparison after two weeks.
