The Mediterranean Posidonia, contrary to what
you might think, is a marine plant, not an algae. In fact it consists of a
root, a stem and leaves that are concerned with the process of photosynthesis.
Its stem, called rhizome, can develop both in horizontal and vertical
direction. Nevertheless the leaves develop only from the vertical rhizome.
The continuous
accumulation of Posidonia forms a network of dead rhizomes called “matte”. These “matte” create a barrier that filters the
carbon footprint in the environment thus reducing greenhouse gas emissions in
the planet. The growth of “matte” is very slow,
that’s why you must avoid destroying them, since it is a phenomenon not
replicable on a human scale. In the Mediterranean Sea you can see the phenomenon of the beaching
of the Mediterranean posidonia. This natural process, that is not harmful to
environmental ecology, damages the tourist economy of the place. For this reason the particular composition of posidonia has
been exploited either for removing it from beaches or for using it for
economical purposes. Because of this, a particular type
of compost ,acting as soil conditioner, has been created.The advantages of the
compost are as follows:
- Increase in the porosity of the soil
- Increase in the bioavailability of soil microflora
