Oxygenated water is used for irrigation in order to sterilize the roots, and make them free from viruses, bacteria, fungi, seaweed, spores, and other microorganisms, thus promoting growth that is fast and continuous, as well as more productive. The cellular processes of respiration are improved by ozone.
Ozonated Water For Irrigation
Microorganisms such as fungi, bacteria, and viruses are all susceptible to ozone’s direct germicidal qualities. Streptococcus, Legionella, Pseudomonas, Flavobacterium, etc. are bacteria that are destroyed by ozone. Bacteria and fungi are the major causes of vegetable degradation in specific cases. Despite the fact that these microorganisms are capable of propagation and reproduction even under extreme conditions, ozone kills them very efficiently.
In the adverse conditions, it is very difficult to eradicate the infection with any other alternative, however, ozone proves to be very effective and provides complete protection. The spores mentioned are very resistant when adverse conditions exist and can remain in latency for a long time, even when spread by air or other means, until suitable conditions are again found for their growth.
Because of its incredible power to eliminate parasitic bacteria, viruses, fungi, and cysts, ozone doesn’t leave toxic compounds behind or leave harmful residues behind, but decomposes back into oxygen when it comes in contact with surface water. Fruit trees, vineyards, and other cultures are greatly benefited by ozone irrigation when it comes to preventing deadly ailments.
Use Of Ozonated Water In Different Materials And Their Benefits
| Commodity | Ozone treatment | Effects on quality |
| Broccoli | 0.04 μL L−1, 7 d, 10 °C | Delay of metabolic process & oxidative reactions |
| Cucumber | 0.04 μL L−1, 17 d, 3 °C | Enhancement of appearance. Higher values of Firmness (N) than the observed in control simples. |
| Mushroom | 0.04 μL L−1, 14 d, 4 °C | Blotch in cap surface was diminished. |
| Apple and pears | 1.5 μL L−1, 100 d, 20 °C | Total soluble solids and firmness were sustained. |
| Orange juice | Ozone variable dose | Control of decay, abatement of ethylene, removing of pesticides and residues. |
| Fresh cut lettuce | 1 mg L−1, 10 d, 4 °C | Storage life increased, decline of respiration rate & enzymatic browning. |
| Cantaloupe melon juice | 7±2.47±2.4 gL−1 for 30 & 60 min | Increase of polyphenols and vitamins. |
| Mango | 10 μL L−1, 3 d, 25 °C | Delay of ripening, Improvement of quality characteristics. |
| Papaya | 2.5–3.5 ppm | Weight loss reduction, higher firmness values. |
| Soil and water deposits | Ozone variable dose | Bactericidal action on responsible for food delay (P.aeruginosa) |
Benefits Of Irrigation Using Ozone
There are several benefits associated with irrigation with ozonated water. These include:
Protects Against Diseases
Infection is the most common cause of various plant diseases. In addition to destroying microorganisms, ozone increases the amount of oxygen in water. Ozonated water is effective in killing bacteria, viruses, and parasitic cysts, which can be difficult to kill using alternative methods. The only gas that does not leave residues and returns to oxygen upon decomposition is ozone, which is not harmful to the environment or humans like pesticides.
Additionally, ozonized water is used to irrigate, store and transport any product, which means that it will maintain its properties for a much longer period of time.
Promotes Better Growth
When ozone is introduced into water, it decomposes and returns to oxygen once it comes into contact with contaminants. This is why irrigation using ozone water contains a higher oxygen content. The water irrigated with ozonized technology is uncontaminated by spores, viruses, bacteria, microbes, or seaweed, other fungi.
Using water without germs will provide the best conditions possible for increased growth, as the plant will have more vitality, more force, and it will be able to grow in a very short period of time (30 to 40 days from the start).
Final Words
Using Ozonated water for irrigation results in a more spectacular and productive harvest, which is obtained in a limited amount of time, saving a great deal of water and reducing the amount of fertilizer and additives required for plants to grow rapidly.
By using Ozonated water for irrigation purposes, fertilizer and additives can be reduced by almost half, leading to a much quicker maturation cycle for crops that represent the same size, strength, and volume as crops irrigated with fertilizer.
