Facts about SiliconSecond 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 limitedOur 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 AgricultureHighest content of Silicon is in soil. Plants also grow in soil. Soil is the medium for Silicon availabilityPlants 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)

Silica requirement

Requirement of Silica is more than most important inputs in Agriculture in key staple crops

Increases cell wall strength

Results in increased tolerance Disease resistance Insect resistance

More upright growth and rigidityIncreased shoot and root densityresulting in higher yieldsRegulates uptake of toxic elementsIncreases heat toleranceSlows transpirationIncreases CEC making other nutrients more available

Impact of Silicon on Plants

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

Abiotic stress today is the biggest factor of productivity loss in today’s agriculture

Unfortunately there is no cure / treatment for this

High Temperature

Abiotic Stresses of Plants

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

Benefits of Silixol

All these factors automatically lead to increase in yield,

quality and storage life of the produce

Water Stress

Reduction in leaf sizeReduction in stem extension and root proliferationdisturbs plant water relations reduces water-use efficiency. Reduced CO2 assimilation by leaves due to stomatal closure, membrane damagedisturbed enzyme activity. Enhanced metabolite flux due to photorespiratory pathway increases the oxidative load and generate reactive oxygen species (ROS).

Alleviation of Stress by Silixol

Abiotic Stress

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
