Can treated wastewater be used for irrigation without compromising vegetable quality?Smrke, Tina (Avtor) Kavkler, Uroš (Avtor) Germšek, Blaž (Avtor) Solina, Borut (Avtor) Lah, Branko (Avtor) Kuzmič, Katja (Avtor) Fras, Matjaž (Avtor) Kuhar G., Antoaneta (Avtor) Žibrat Gašparič, Andreja (Avtor) Cvelbar Weber, Nika (Avtor) irrigationwastewatertreatment plantvitaminsreverse osmosisultrafiltrationwater shortageIrrigation of plants in agriculture will become a problem in the future due to water shortages. One of the most appropriate solutions is to irrigate plants with treated wastewater from treatment plants. In our study, we irrigated pepper, carrot, and onion plants with fresh water, water treated by reverse osmosis, and water treated by ultrafiltration. We analysed the effect of each treatment on the content of individual vitamins in the edible parts of the plants. The results showed that irrigation with treated wastewater does not affect the content of individual vitamins in peppers and carrots. In onions, only the riboflavin (B2) content differed between treatments, with the highest content detected at treated wastewater. The study provided some promising results, as we did not detect any negative impact of irrigation with treated wastewater on the quality of the edible parts of peppers, carrots, and onions. In the future, it would be good to focus on testing other plant species, such as strawberries.20262026-05-22 09:58:51Neznano29501sl
