Silicone-rich potting mix: I haven't tried it yet
IÃ¯Â¿Â½ve read about siliconÃ¯Â¿Â½s role in biology, a thing that is normally ignored by most gardeners, as it seems to take some part in biology, and not only geology. It was found that Silicone has a positive impact on bone health
Although Silicone is abundant and is present as Silicone dioxide (SiO2) in the form of sand, adding sand to your meal won't do any good. We would normally eat plants containing silicone, or eat animals which consume these plants.
It has a positive effect on plant health, reducing susceptibility to biotic (pests, diseases) stress as well as abiotic stress (mineral imbalance, mineral distribution, harmful UV rays) as shown here
This has prompted me to think how to make a silicone-rich potting soil, or a bio-silicone additive. There are two plants I know about which are rich in silicone: Horsetail (e.g. Equisetum arvense) having as much as 10% silicone and bamboo. http://en.wikipedia.org/wiki/Equisetum_arvense
Has anyone tried to make potting soil from these plants? If we take composted bamboo chips instead of composted wood chips, or we use the same process of turning sphagnum moss into peat soil, but use horsetail instead, we should get silicone-rich potting soil. If silicone content is too high, we may just use it as additive for peat soil.
