Agricultural Fact Sheet
Everyone knows the importance of oxygen
in soil….
Any crop grows much better with rainwater than with irrigation water. This observation
indicates a clear difference between rainwater and other irrigation water such as river-,
dam- and borehole water. The difference lies in the oxygen composition of the water, but
more specifically the presence of different forms of activated oxygen (O3, O4, O5, .… OX) in
rainwater.
How does the oxygen difference originate? The air in our atmosphere contains 20.8%
oxygen (O2). There are different frequencies of UV rays from the sun which each has its
own function. As the specific frequency shines through the atmosphere, the oxygen (O2) is
changed to activated oxygen (O5, O7, O11, …. OX). During the precipitation process the
activated oxygen becomes part of the raindrops, after which this oxygen enriched water
reaches the soil.
Many farmers are of the opinion that improved plant growth is due to the presence of
nitrogen in rain water. However, Nitrogen fixation in the atmosphere happens only when
there is lightning activity, and general rainwater (without lightning) contains relatively low
levels of fixated nitrogen. Improved plant growth is the direct result of oxygen enriched
rainwater which infiltrates the soil and creates an aerobic climate.

What is Ozone?
Ozone is a composition which naturally occurs in the atmosphere. This activated oxygen
molecule consists of three combined oxygen atoms.
3 O2 + (radiation) → 2 O3
Three oxygen molecules are required to form two ozone molecules.
3
Ozone (O3) is highly unstable and attempts to return to its natural form (O2) as soon as
possible. The additional oxygen atom reacts (through oxidation) with anything that is
present in the water. Oxidation can happen with metals, organic materials and even living
tissue. Ozone is a strong oxidising agent and is nature’s way to get rid of toxic gasses in the
atmosphere.
The Puricare Agricultural Unit
The unit is used to imitate nature and convert standard irrigation water into water that acts
as efficiently as rainwater.
How does the Puricare Agricultural Unit work?
Ozone (O3) and activated oxygen (O5, O7, O11, …. OX) are produced in a natural way when a
specific air volume, at a specific flow velocity, moves past a UV light with a specific
frequency. The oxygen in the air is irradiated to form ozone (O3) and activated oxygen (O5,
O7, O11, …. OX) which are dissolved into irrigation water through a combination of pressure
pumps, sputniks and venturis. Due to the high pressure under which the ozone and oxygen
are kept during the inflow to the system, the gasses are dissolved in the water. Thereafter
peroxide is added to the ozone enriched water. The Puricare Agricultural Unit enables
advanced oxidisation processes (GOP or peroxide) to happen in the irrigation water where
hydrogen peroxide (H2O2) activates (catalyses) and accelerates the reactions.
What are the features of the Puricare Agricultural Unit?
The unit consists of 3 main components, which are: UV light(s), an activated oxygen
dispensing mechanism and a hydrogen peroxide dispensing pump.
The Puricare Agricultural Unit can be installed on any irrigation system (flood-, sprinkler-,
pivot-, micro-, hydroponic irrigation system etc.) and treats all types of irrigation water.

The Puricare Agricultural Unit cannot cause corrosion of irrigation systems
When activated oxygen is dissolved in irrigation water, advanced oxidisation processes take
place with metals, minerals, bacteria and virrusses which are present in the water. The
applied dosage is so low that no residual free ozone/activated oxygen remains to react with
the irrigation system (pipes, galvanised fittings, rubbers etc.) and the treated water therefor
does not act corrosively. No activated oxygen is present in the water by the time it reaches
the drippers, only oxygen enriched water. Our units also do not create nitris oxides, which
can cause corrosion of irrigation systems.
A typical installation where 2 400 000 litres per hour is treated. There is no
limit on the volume of water that can be treated.
5
Corrosion of irrigation systems is mainly due to the high electrolytic content of the water,
e.g. water from the Vaal river has a higher electrolytic content than irrigation water from the
Orange river, which causes irrigation systems to rust. The Puricare Agricultural Unit’s
advanced oxidisation processes balance the electrolytic effect of the water and no corrosion
takes place.
Primary benefits for Agriculture
The continuous cleaning of irrigation systems
Oxidation of deposits in the irrigation system starts immediately and can take between three
weeks to six months, depending on how blocked the system is, and how frequently irrigation
takes place.
Further advantages:
- Less blocked drippers saves labour and leads to a higher efficiency of the
irrigation system.
- The cleaner irrigation system lowers the workload at the pump and saves electricity.
- A shorter irrigation cycle saves electricity.
- Filters stay cleaner for a longer period of time.
- The lifespan of the irrigation system is prolonged and maintenance costs are
lowered.

The Puricare Agricultural Unit releases low concentrations of ozone which causes the
deposits to be oxidised from the centre of the pipes to the sides over a period of time.
These ozone concentrations are too low to break the bond between the deposits and the
irrigation pipes, and will not cause larger deposits and blocked irrigation pipes.
Improved water quality
The activated oxygen, with which the irrigation pipes are cleaned, is dissolved in the
irrigation water and improves the water quality.
- The pH of the water improves due to the oxidation of minerals and salts.
- The oxygen enriched water infiltrates and penetrates the soil faster due to an
improved crystal structure.
- Less run-off and evaporation of applied water.
- Water consumption is more efficient.
- This leads to a decrease in water applications.
- The activated oxygen in the water oxidises harmful minerals, making the water more
easily absorbable to plants.
- Bacteria, viruses and other harmful organisms in the water can be oxidised and
infections can decrease.
Improved soil quality
The Puricare Agricultural Unit aims to return soil conditions back to its natural balance. The
application of oxygen enriched irrigation water increases the oxygen levels in the soil,
enlarges the porous between the soil particles, which leads to better aeration of the soil,
improves the soil pH and structure, reduces compacted soil conditions and ensures better
absorption of water.

Secondary benefits of improved soil quality:
- The soil’s resistance to root growth is diminished and better root growth takes place
- resulting in better absorption of water and nutrients.
- Soil organisms and micro life in the soil are stimulated. Where stress conditions exist,
(e.g. compact soil, element toxicity etc.) a higher concentration of pathogenic or
disease causing organisms can be found. When the soil quality is restored, the
concentration of beneficial microbes in the soil increases, and a balance is achieved
between the positive and negative soil organisms.
- Better water absorption and less run-off, is achieved by improved soil quality.
- Applied fertilizer is more effective due to it being more accessible for root growth
through oxidation and increased organism activities. Increased accumulation of
fertilizer and other nutrients in the soil are also oxidised to a biodegradable form
more accessible to plants.

- Where plant material is applied as mulch, an increase in the organic material content
of the soil is obtained. Activated oxygen can break down organic materials to carbon
level, but due to the fact that there is no more activated oxygen in the water by the
time it reaches the drippers, the oxygen enriched water can only stimulate the
microbe life to break down the mulch to organic carbon.
Improved root growth
A well-developed root system is indispensible for crop production, since plants absorb most
of their nutrients and water through their roots. The high oxygen content in the root zone
(rhizosphere), the lower resistance of the soil against root growth and better availability of
nutrients are factors which contribute to an improved root system.
Plant roots are healthier, root hair growth is stimulated and the root periphery is increased
by the use of the Puricare Agricultural Unit.

A favourable environment is created for the symbiotic growth of Mycorrhiza which greatly
improves the absorption of water and nutrients (up to 100 times). Mycorrhiza also enhances
plant resistance against pathogens, drought and certain toxic conditions in the soil.
Healthier, stronger plants
An improved root system absorbs more plant nutrients, stronger and thicker stems are
formed which better translocates the nutrients to leaves, flowers and fruit.
Stronger stems can also carry more/larger leaves and fruit.

Denser foliage and increased shade limits weed growth and leads to cooler soil.
Observations were made that creeping weeds (common on compacted soil) were less
present and that the growth of grass and natural weeds have increased.
How does the farmer benefit from the
Puricare Agricultural Unit?
Many farmers ask for scientific evidence to explain higher yields, improved plant growth or a
decrease in disease incidence. These results are, however, influenced by various aspects
and reactions. It is not always possible to explain each result scientifically. Each farm’s
history, soil structure, crop preference, farming practices and disease/pest incidence are
different, yet the use of the Puricare Agricultural Unit repeatedly showed improved
circumstances.
We can proudly say that most farmers give positive feedback and that there is evidence of
decreased expenses – through reduced water usage, less maintenance of irrigation systems
etc.
