Action of activated waters on plants after adverse chemical effects, imitating acid rain
Teodora P. Popova, Toshka E. Petrova, Metodi Petrichev, Miglena Valyova
Abstract: Studies have been carried out to test the effect of catholytes for protection of plants from the species coriander (Coriandrum sativum), oregano (Origanum vulgare), lemon balm (Melissa officinalis), mint (Mentha piperita) and mint (Mentha spicata) after treatment with sulfuric acid solutions with pH 4.87, 5.76 and 5.91, resembling acid rains. The results show that acid rains have an adverse effect on plants, even at relatively low acidity. They damage the plants and cause a loss of freshness, etiolation and some of them die after their effects. The most vulnerable to acid rain effects are the coriander, M. spicata and oregano, and the most resistant is the lemon balm. The present studies show for the first time that catholytes prepared with 0.05% NaCl, also with a combination of 0.05% NaCl and 0.05% Na2CO3 as well as 0.4% NaCl and 0.4% Na2CO3, and applied 1.5 hours after treatment with acidic solutions, have a beneficial effect on the plants. Two-fold treatment with catholyte is more effective than one-off, although the differences are not significant. It has been established for the first time that catholyte can be a reliable and effective remedy for plant protection in order to prevent significant damage to plants and ensure their rapid recovery after acid rains.
