Rehabilitation of Degraded and Contaminated Soils Using Ozone Gas Injection Technology: A Specialized and Sustainable Solution

OzonAb, a technical and engineering company, leveraging indigenous expertise and advanced technologies, offers an innovative solution for the rapid and safe rehabilitation of agricultural soils, orchards, and livestock and poultry farming facilities: soil restoration through ozone gas injection. This method represents a scientifically robust and highly effective alternative to costly and low-efficiency practices such as soil replacement, prolonged land fallowing, or repeated use of chemical pesticides and fertilizers.

Common Challenges in Degraded Soils:

• Severe reduction in soil fertility and deterioration of soil structure (compaction, reduced aeration, and permeability).
• Residual pesticides, herbicides, and persistent organic contaminants accumulated in deeper soil layers.
• Prevalence of soil-borne fungal and bacterial diseases such as Fusarium, Pythium, and Verticillium.
• Accumulation of nitrogenous and sulfur compounds causing unpleasant odors (e.g., ammonia and hydrogen sulfide).
• Immobilization of essential nutrients (such as phosphorus and potassium), rendering them unavailable to plant roots.

Mechanism of Ozone Gas Injection in Soil Rehabilitation:

In this process, ozone gas (O₃) at precisely calculated concentrations and doses is directly injected into subsurface soil layers (to the required depth). Ozone, with its exceptional oxidation potential, restores soil quality through several mechanisms:

• Detoxification and Sterilization: Direct oxidation and decomposition of residual pesticides, herbicides, and organic pollutants, along with the elimination of a wide range of harmful pathogens (fungi, bacteria, nematodes, and weed seeds), without leaving any persistent chemical residues.
• Improvement of Soil Physical Structure: Decomposition of compacted organic matter increases soil porosity, reduces bulk density, and enhances aeration and permeability. This significantly improves root access to oxygen and water.
• Neutralization of Harmful Compounds and Nutrient Release: Oxidation of odorous nitrogenous compounds (such as ammonia) into nitrogen gas, and disruption of chemical bonds that immobilize nutrients, thereby releasing them back into the plant nutrient cycle.
• Enhancement of Soil Self-Regeneration Capacity: By removing inhibitory factors, ozone stimulates the activity of beneficial soil microorganisms, facilitating the restoration of ecological balance and natural soil fertility.

Our Specialized Operational Process:

OzonAb’s services are delivered as a fully engineered and phased project:

• Phase One: Diagnosis and Analysis (Free Sampling): Standardized sampling from multiple locations and analysis of key parameters including pH, EC, soil texture, and qualitative and quantitative identification of contaminants.
• Phase Two: Injection Protocol Design: Development of an operational plan based on analytical results, including precise determination of injection depth, required ozone dosage, session scheduling, and projected outcomes.
• Phase Three: On-Site Implementation Using Portable Ozone Generators: Field execution using advanced equipment, without the need for soil relocation or land disturbance. Operations are typically completed intensively within one to two sessions.
• Phase Four: Results Monitoring and Certification: Measurement of final performance indicators, submission of a comprehensive written report, and issuance of a soil health certificate, ensuring effectiveness and rapid readiness of the land for cultivation.

This method not only significantly reduces fertilizer and pesticide application costs, but also ensures long-term sustainability and productivity of agricultural and orchard ecosystems by eliminating contaminants and restoring soil health.
