Facts about Silicon
Second largest element (~ 28%) on Earth, next to only Oxygen
Ubiquitously present almost everywhere as silicates and other
forms
Despite its large abundance it is utilized by plants in small amounts
Polymeric forms of existence.
Ortho Silicic Acid (OSA) if only bioavailable form of Silicon
Diatoms and soil microbes contributes towards availability of this
form
Supply is highly limited
Our technology/formulations provides OSA in a stabilized form so that they
can directly utilized by all living organisms
Importance of Silicon
Contribution of beneficial roles of silicon had been overseen in
past
Early 1990’s its essentiality had been proven by scientists.
In 1999, First International Conference on Silicon in Agriculture
was held in Florida.
Considered as a frontline for evolution
Silicic acid polymers are compatible with all biomolecules like
sugars, proteins, nucleic acids
Known to play key role in development and growth of both plants
and animals.
2011, the Association of American Plant Food Control Officials
designated silicon as a “plant beneficial substance”
Silicon and Agriculture
Highest content of Silicon is in soil. Plants also grow in
soil. Soil is the medium for Silicon availability
Plants with low soluble silicon levels have a greater
susceptibility to disease, drought stress and other
plant stresses
Silicon reduce phosphorus leaching while at the same
time increasing phosphorus plant availability.
Silicon’s activity in the soil matrix has been proven to
improve micro-nutrient uptake (Cu, Mn, Zn B)
Reduce toxic metal uptake (Al, Na)

Agriculture in key staple crops
Impact of Silicon on Plants
Increases cell wall strength
Results in increased tolerance

Disease resistance

Insect resistance
More upright growth and rigidity
Increased shoot and root density
resulting in higher yields
Regulates uptake of toxic
elements
Increases heat tolerance
Slows transpiration
Increases CEC making other
nutrients more available
Benefits of Silixol
Direct Role of Silicon in Plant
Health
silicon makes up between 0.2 and 10% of
a plants dry weight.
Associates with cell wall proteins
Prominent in cell walls as solid amorphous
silica, providing a structural barrier to
pathogens
Translocated from roots to shoots and
vica versa

this???
Abiotic stress today is the biggest factor of productivity loss
in today’s agriculture
Unfortunately there is no cure / treatment for this
Silixol plays vital role as preventive measures to alleviate Abiotic Stress

Benefits of Silixol
Silixol improves plant resistance against water, soil
and temperature stress
Silixol enhances nutrient uptake thus providing
strength to the roots and plant
Silixol is non-toxic and leaves not residue in the
produce
Silixol improves plant resistance to fight against
fungal, insect and mite attack
All these factors automatically lead to increase in yield,
quality and storage life of the produce
Water Stress
DROUGHT
Reduction in leaf size
Reduction in stem extension and
root proliferation
disturbs plant water relations
reduces water-use efficiency.
Reduced CO2 assimilation by
leaves due to stomatal closure,
membrane damage
disturbed enzyme activity.
Enhanced metabolite flux due
to photorespiratory pathway
increases the oxidative load and
generate reactive oxygen
species (ROS).
Water Stress
WATER LOGGING
Reduction in stem extension and
root proliferation
disturbs plant water relations
reduces water-use efficiency.
Damage of root tips due to lack
of oxygen
membrane damage
disturbed enzyme activity.
Reduced uptake of nutrient
High incidences of soil borne
pathogen
Accumulation of toxins due to
anerobic respiration
Heat Stress
Sun burning of different plant parts
apoptotic cell death are also activated.
Dried look to plants
Loss of plant turgidity
Drop in flower and fruit
inhibition of normal transcription and
translation,
higher expression of heat shock proteins
Cold Stress
Enhance the transcript, protein
High activity of different ROSscavenging enzymes.
Increase the H2O2 accumulation in
cells.

Stress Relief Mechanism
◦ Increased Production of Antioxidants
◦ Binding and co-precipitation with Metal Ions
◦ Immobilization of Metal Ions in the soil
◦ Modification of element uptake processes.
Silification of leaf surfaces can significantly decrease water
loss by transpiration and thus reduce drought stress
Leaf cooling through the efficient mid infrared thermal
emission of silica can increase heat tolerance
Accumulation of osmolytes in cells to overcome water loss
Stress management by Silixol
Biotic Stress

Silicic acid induces plant defense mechanism by production of
antifungal or antibacterial compounds



Studies have shown that Silicic acid induces higher level of
phytoalexins in following crops
◦ Increasing the resistance of Rice to blast
◦ Increasing the resistance of wheat to powdery mildew
Bacterial and Fungal damage in crop plants is reduced when silica
is deposited at sites of attack , mechanically impeding pathogen
penetration
