WHAT ARE SILICATES? |
|
|
|
|
|
|
A silicate is a compound containing an ion in which one or more
central silicon atoms are surrounded by electronegative ligands.
This definition is broad enough to include species such as
hexafluorosilicate ("fluorosilicate"), [SiF6]2−, but the silicate
species that are encountered most often consist of silicon with
oxygen as the ligand. Silicate anions, with a negative net
electrical charge, must have that charge balanced by other cations
to make an electrically neutral compound. |
|
| |
Silica, or silicon dioxide, SiO2, is
sometimes considered a silicate, although it is the special
case with no negative charge and no need for counter-ions.
Silica is found in nature as the mineral quartz, and its
polymorphs. |

Silica as Plant Nutrient:
Silicates make the cell walls of the plants thicker and stronger
while also increasing the size of the vascular system of the plant.
The thicker cell walls translate to the plant being stronger in all
aspects, while the enlarged vascular system can take up more water
and nutrients resulting in a bigger, healthier, higher yielding
plant! The larger the plant's vascular system, the more potential
the plant has for maximum yield. |

Mostly silica is deposited on leaves and
stems of plants, and some effects are through interaction
between silicic acid and other elements such as Al. In
contrast to essential elements, the function of Silica in
plants is probably mechanical rather than physiological.
This characteristic of Silica function explains why Si
effects are easily observed in plants that accumulate Silica
to a certain extent and why Si effects are more obvious
under biotic or abiotic stress. With the changes occurring
in the global environment, the role of Silica will become
more and more important for better and sustainable
production of crop. |

Targets of a suitable Silica fertilizer: |
- Cheaper Source
- Easy application,
- Higher content of soluble Silica
- Ready availability,
|
Silica is the second most abundant element in the earth's crust. It
is always combined with other elements and many of these sources are
insoluble. Responses of crops to soluble Silica applications in
sands (largely SiO2) provide an example of the insolubility of the
sandy soils. Although basic slags (by-products) from the processing
of iron and alloy industries, have been used, their concentrations
and solubility of Silica and the contents of other elements and
their bondage vary widely. Potassium silicate is used in
nutriculture for disease control in some high value crops but are
too costly for general use.
Sodium silicate and silica gel have also been used to supply Silica
in research and high value crops. Calcium silicates have emerged as
the most important sources for soil applications. Of those, calcium
meta-silicate (wollasonite, CaSi03) has been the most effective
source in many locations with low concentrations of soluble Silica
in soils. Such a material, supplied as a slag by-product from the
high temperature electric furnace production of elemental P is
applied extensively to organic and sandy soils for application for
sugarcane and rice crops as well as utilization on turf. |
