“…Plasma agriculture applications of non-equilibrium atmospheric-pressure plasma (NEAPP) have been used for inactivation of microorganisms [77], decontamination [78], enhancement of seed germination and plant growth [79] and DNA introduction [80]. The inactivation of microorganisms by NEAPP can be effective at protecting agricultural crops and food storages from pathogenic insects and bacteria.…”

“…3,4,37,38 The improved germination by plasma discharge on the seed surface can be correlated to several factors such as increase in surface wettability, 14 killing of bacteria and pathogens on the seed surface. 20,21 In addition, the local heating probably opens up the seed coating and increases the water intake.…”

The combined effect of non-thermal plasma treatment of water and seeds on the rate of germination and plants growth of radish (Raphanus sativus), tomato (Solanum lycopersicum), and sweet pepper (Capsicum annum) have been investigated using dielectric barrier discharges in air under atmospheric pressure and room temperature. A cylindrical double dielectric barrier discharge reactor is used for water activation and a plate-to-plate double DBD reactor is employed for seed treatment. The activation of water, for 15 and 30 min, lead to acidic solutions (pH z 3) with moderate concentrations of nitrate (NO 3 À ) and hydrogen peroxide (H 2 O 2 ). Plasma activated water (PAW) has shown a significant impact on germination as well as plant growth for the three types of seeds used. Interestingly, the positive effect, in seed germination and seedling growth, has been observed when the PAW and plasma-treated seeds (10 and 20 min) were combined. In one hand, when the seeds were (tomato and pepper) exposed to 10 min plasma and watered with PAW-15 for first 9 days followed by tap water for 51 days, the stem length is increased about 60% as compared to control sample. On the second hand, for longer exposures of seeds and water to plasma discharges, a negative effect is observed. For instance, plasma-treated seeds watered with PAW-30, the plant growth and vitality were decreased as compared to control sample.These results revealed that the developed cold plasma reactors could be used to significantly improve the seed germination as well as plant growth, nevertheless, the plasma treatment time has to be optimized for each seeds.

“…Trials employing usage of electrical discharges, ozone alone or combined with AOTs were performed for the treatment of soil and plants by international research groups [6][7][8][9][10][11][12][13][14]. Application of AOTs helps to preserve natural structure of the soil, prevents its acidification, leaching and releasing metallic compounds.…”

In many locations, generation of electrical energy is restricted due to unfavorable logistic conditions. That limits introduction of new technologies, requiring electrical power including air, water and soil purification technologies. Small scale treatment installations supplied with electric energy from solar sources were proposed as a good example of zero-emission technology achieved with reasonable cost. Treatment process of agricultural samples, pathogens and pests based on ozone and advanced oxidation process was described.
