Plasma–Liquid Interaction for Agriculture—A Focused Review

ABSTRACT In this review, we give an overview of the applications of plasma activated water (PAW) and its chemistry in the field of agriculture. This article concentrates on the chemistry of long‐lived reactive species and their roles in plant cell mechanisms. The chemical reactions important for the creation of nitrate, nitrite, and hydrogen peroxide inside water during the production of PAW and their chemical paths inside the plant cells are discussed. We describe the use of different types of discharges for PAW production and present the results of PAW application to seeds and plants. We address the decontamination of agricultural chemicals in water along with the scarcely explored topic of water remediation. The major challenges and future possibilities for PAW in agriculture are also discussed.
