Benefits of Fulvic acid
1. Fulvic acid is nature’s life restorer – the electrolyte theory
Fulvic acid is a natural organic
electrolyte.
Balance, activate and energize biological
properties of organic materials.
Prevents cell disintegration and death..
By restoring its normal chemical balance
and electrical potential.

2. Promotes electrochemical balance –donor or receptor
Electrochemical balance is required for
health in any organic system.
Fulvic acid helps in fulfiling the
requirement for balance.
During oxidation – species loses
electrons as donors.
Fulvic Acids
During reduction – species gains
electrons as acceptors.
Fulvic acid actively involves in donoracceptor charge transfer mechanisms.

3. Fulvic acid dissolves minerals and trace elements
Fulvic acid dissolves minerals and metals
when in solution with water.
Metallic minerals dissolve into the Fulvic
structure.
Then they becomes bio-chemically
reactive and mobile.
It transforms these minerals and metals
into Fulvic acid complex structure.

Fulvic acid
It has also the ability to weather and
dissolve silica into assimilable form in soil
Fulvic acid dissolves metals

4. Fulvic acid enhances nutrient availability and assimilation
Fulvic acid enhances availability of nutrients and makes them readily absorbable.
This is because of the fulvic acid electrolyte
chelation.
It facilitates inter-nutrient interaction and
breaks them down to simplest ionic forms.
The metalic organic complexes have small
molcular size and can easily penetrate cells.
.
Fulvic acid helps transport
nutrients through cell wall and
sensitize cell membranes

5. Fulvic acid catalyzes enzyme reactions.
With Fulvic acid
Fulvic acid increases the activity of several enzymes like transaminase and
invertase.
Talk to us. It pays.
Web: www.omnia.com.au
Transminase enzymes are important in the production of various amino acids.
Amino Acids
Proteins
Building
blocks of cells
More living cells means higher growth rate (Yield and quality).
Talk to us. It pays.
Invertase is a digestive enzyme
Invertase
Monosaccharides
Monosaccharides tend to be absorbed and become available
as an energy source more quickly
Talk to us. It pays.
6. Fulvic acid stimulates metabolism
It causes the genetic mechanism of plants to function at a higher level and
improve growth.
Oxygen is absorbed more intensely
Hence increases the vital activity of cells
It changes the pattern of metabolism
This results in accumulation of soluble
of carbohydrates
sugars
A higher osmotic pressure is created
Which enable plants to withstand wilting
inside the cell wall because of this
Also stimulates the immune system

7. Fulvic acid detoxifies pollutants
Fulvic acid helps the formation of new species of metallic ions.
These binds with pesticides to catalyze breakdown of toxic pollutants.

8. Fulvic acid increases metabolism of proteins
Fulvic acid intensifies
metabolism of RNA and DNA.
Fulvic acid increases DNA
content in cells.
This will positively impact cell size and disease resistance

9. Fulvic acid catalyzes vitamins within the cell
Fulvic acid has the ability to introduce
vitamins into its structure.
And presented to the cell with
complex mineral structures.
In this condition, the vitamins can be
catalyzed and utilized by the cell.

10. Fulvic acid chelates Mon, Di & Trivalent elements
Fulvic acid has the power to form stable
water soluble complex structures.
With mono-valent, divalent, trivalent and
Mono/
Mono/Di/
Di/Trivalent
Trivalent
Elements
metals
polyvalent metal ions.
Helps the movement of metal ions that are
normally difficult to mobilize.

11. Fulvic acid as spray adjuvant
Fulvic acid can be used as spray adjuvant.
Especially with herbicides to increase
efficiency (absorption).
At the same time, prevents adverse effect
of herbicides on Soil micro flora and fauna.
As well as potential downstream pollution.

Differences between Fulvic and Humic acids
HUMATES : Large Molecules
FULVATES : Medium Molecules
Not easily absorbed through leaves
Readily and quickly absorbed through
leaves
Provide sustained food for microbes –
sustained benefit in soil
Quickly degraded and consumed in
soil – still beneficial for microbes
Break down in soil over time to form
Instantly available and absorbed by
fulvates – sustained release of fulvates plants – short duration effect
Bound to soil particles. Not readily
Not strongly bound to most soils.
leached – retain nutrition and moisture Readily leached and lost from soil – no
in soil with sustained benefit in the root long term conditioning effect
zone
KEY POINTS
Slow acting, effective in the soil,
soil conditioner
Fast acting, effective on leaf, low
effect as soil conditioner
