49. Plasma Activated Water (PAW)

Published on February 11th, 2026

Interest in PAW is growing in the UK and internationally as farmers look for sustainable tools that support plant health, reduce reliance on imported fertiliser, and improve resilience. Research indicates PAW can enhance seed germination, root growth, disease suppression, and nutrient availability.

Plasma Activated Water (PAW) is created when atmospheric plasma interacts with water, producing a solution rich in reactive oxygen and nitrogen species (RONS) such as nitrates, nitrites, hydrogen peroxide, and ozone. These compounds give PAW antimicrobial properties and can act as a mild nitrogen source, making PAW a promising chemical-free input for agriculture. PAW is emerging as a potential alternative to conventional fertilisers, seed treatments, and pesticides, and can be produced on‑farm using only air, water, and electricity. [plasmatrea…ment.co.uk]
