The effect of lifting DO and Ozone and Hydroxyl radicals on soil health through irrigation.
The effect of lifting dissolved oxygen (DO) levels and using ozone and hydroxyl radicals in irrigation water on soil health can be both positive and negative, depending on various factors such as concentration and application method.
Increasing dissolved oxygen levels in irrigation water can promote the growth of beneficial soil microbes, which can help improve soil health. This can result in better nutrient availability and uptake by plants, leading to improved plant growth and yield. However, excessive levels of dissolved oxygen in irrigation water can also have negative effects on soil health by promoting the growth of harmful soil microbes that can damage plant roots and cause soil compaction.
The use of ozone and hydroxyl radicals in irrigation water can also have both positive and negative effects on soil health. Ozone can be used to disinfect irrigation water and control soil-borne pathogens, which can help improve soil health. Hydroxyl radicals are known to promote plant growth and yield, which can indirectly improve soil health by increasing the organic matter content of the soil. However, excessive use of ozone and hydroxyl radicals in irrigation water can also have negative effects on soil health by reducing the population of beneficial soil microbes and disrupting the soil ecosystem.
Dissolved oxygen (DO) is an essential component for soil health as it plays a vital role in supporting aerobic soil microbes that are essential for nutrient cycling and decomposition of organic matter. Oxygen is required by microbes for respiration, and without adequate oxygen, anaerobic microbes may proliferate, leading to soil degradation and reduced soil health.
Ozone (O3) is a highly reactive gas that can be used in irrigation to help reduce the level of contaminants and pathogens in water. Ozone can be used to oxidize organic compounds and inactivate pathogens, such as bacteria and viruses, that can be harmful to soil health. However, care must be taken when using ozone in irrigation as it can also be harmful to beneficial microbes in the soil.
Hydroxyl radicals (OH•) are highly reactive and are one of the most potent oxidants known. Hydroxyl radicals can be produced in water through a process known as advanced oxidation, which involves the use of various oxidants such as hydrogen peroxide, ozone, and ultraviolet light. Advanced oxidation has been shown to be effective in removing organic pollutants and pathogens from water. However, the use of advanced oxidation in irrigation water may also affect soil health by potentially killing beneficial soil microbes.
In general, the effect of lifting DO and using ozone and hydroxyl radicals on soil health through irrigation will depend on several factors such as the concentration and duration of exposure to these factors, the type of soil, and the specific microorganisms present in the soil. While these treatments may be effective in reducing contaminants and pathogens in
irrigation water, care must be taken to minimize any potential adverse effects on soil health by using appropriate treatment concentrations and durations, and by monitoring soil health over time

This study investigated the effects of ozone treatment on soil microbial community and enzyme activities. The results showed that ozone treatment significantly reduced the abundance of certain microbial groups, while increasing the activity of certain soil enzymes. The authors suggest that ozone treatment can have both positive and negative effects on soil health and microbial activity.
