Natural Chelates and Bio-stimulants

Peroxstim™ is a water conditioner containing bio-degradable sequestering agents which act as both a natural chelate and a bio-stimulant. This colourless high-density solution is exclusively formulated and manufactured by Humefert Manufacturing (Pty) Ltd. for H2i (Pty) Ltd. for the use with the Oxi-App™ system.


Peroxzone and other oxidants generated by the Oxi-App™ system, continuously treat the irrigation water, break down impurities and the treated water percolates into the soil profile. Throughout the whole process, water quality is optimized, the irrigation system is kept clean, soil compaction reduced, and a more ideal environment is created in which soil life can flourish. Peroxstim™ is continuously added to optimise the process by chelating the individual cations released during oxidation and to stimulate and sustain the soil microbes in the root zone. Peroxstim™ is a scientifically proven natural chelate and bio-stimulant which has been successfully used in the agricultural Industry for the last 15 years. Since it is completely hydrolysed and oxidized during the manufacturing process, 


Peroxstim™ is not affected by the ozone and hydrogen peroxide produced by the Oxi-App™ system and is transferred through the irrigation system and applied directly to the root zone.

Benefits of Peroxstim™: ·

  • Is stable and inactive in a highly oxidative environment (H₂O₂ and O₃).
  • Activated only once the oxidants are broken down completely.
  • Excellent chelating properties.
  • Acts as a slow-release carbon source and nutrient for soil micro organisms.
  • Stimulates root and shoot growth.
  • Increases the absorption rate of most plant nutrients.

Nanobubble Technology (NBT)

Nanobubbles are extremely small gas bubbles that have several unique physical properties that make them very different from normal bubbles. These properties make Nanobubbles a superior aeration method for several applications around the world.

  • It increases the solubility and delays the rapid decomposition of Oxone in water.
  • Neutral Buoyancy – Nanobubbles will remain suspended in water much longer than ordinary bubbles.
  • Surface Charge – Nanobubbles have strong negative charges.
  • Gas Reserve – The neutral buoyancy and negative surface charge of Nanobubbles allows them to remain in suspension for months at a time.
  • Oxygen Transfer Efficiency – Nanobubbles have more than 400 times the surface area of a typical micro-bubble.
  • Oxidation – Nanobubbles form reactive oxygen species such as hydroxyl radicals (OH-) which accelerates oxidation processes.

Intense Oxidation Technology (IOT)

These are a combination of chemical water treatment processes using air, ozone and peroxide in a unique delivery system to reduce biological, organic and inorganic impurities in water by creating highly reactive oxidative species throughout the treatment process.

Although the reaction between Ozone (O₃) and Hydrogen peroxide (H₂O₂) has been studied for years, there are still unanswered questions as to what intermediates are formed. One reason why this combination of oxidants is so powerful is that an intermediate molecule Peroxone (dihydrogen trioxide) or H₂O₃ can be formed which is more potent than either O₃ or H₂O₂ by themselves.

IOT works in many different ways to optimize irrigation water and clean the irrigation system.

• Carbonate Oxidation 

• Salt dissolution and increased Calcium ion availability

• Iron, Manganese & Chlorine Oxidation

• Pesticide, Biological and Biofilm breakdown
