TheVetiver systemis defined as the most promising green technology againsterosion. TheVetiver systemexploits the growth capacity of the root system of a plant, theChrysopogon zizanioides,commonly known by the name ofvetiver.

In the Far East they call it the miraculous plant. The vetiver it is a perennial herbaceous plant that has a very deep root system that reaches and even exceeds 5 meters. To popularize the vetiverin the field ofnaturalistic engineeringit is precisely the characteristics of the root system that can be summarized as follows:

  • Extreme depth of growth of the root system, up to over 5 meters.
  • Very fast root growth rate.
  • Thin, homogeneous, dense and extremely strong roots (1/6 of a medium quality steel).
  • Resistant roots both in acid soils and in basic soils with pH between 4 and 12.
  • The roots do their job wellanti-erosivealso in salivary areas.
  • The roots do their job wellanti-erosivein a very wide range of temperatures, from -10 ° C up to 60 ° C.

Thanks to the features listed above, thevetiverfinds countless applications in the field ofnaturalistic engineeringwhere it is very famous for its ability to "harness" any terrain making it almost immune to erosive phenomena.

Among the various applications, thevetiver systemit is used for the consolidation of road and railway embankments, to protect the banks of streams and rivers and to restore exhausted mines.

The vetiver it is a herbaceous plant with a thousand uses: on the one hand its essential oils are required by the cosmetic industry, on the other hand the properties of its parts are famous in the Ayurvedic method (traditional Indian medicine), up to the point of reachingnaturalistic engineeringwhere is thevetiver systemis famous for counteractingerosionsand for water purification (phytodepuration).

In Italy there are many places that have successfully relied onvetiver systemto contain the problems related to erosive phenomena. Not just against thehydrogeological instability, thevetiver systemit is used innaturalistic engineeringto contain water and soil pollution, in agriculture and in the energy sector, to produce fuel in biomass power plants.

The Vetiver System

Thevetiver systemis a work ofnaturalistic engineeringwhere plants can replace or integrate with civil works. Thanks to the dense root system, thevetivergoes to consolidate and conserve the soil. Thevetiver systemit is widely used to protect infrastructural works, to restore polluted areas (the roots have the ability to absorb pollutants from the soil and water) and for water purification.

Thevetiver systemit is a safe, effective and low cost solution. Given the simplicity of the principle of this system, this can also be applied in a domestic form by a private individual or on a very small scale, for example, by gardeners who must contain a particularly clayey moat that collapses at the first rain. In the home, it can be used to give more stability to the walls and on a large scale it can be used to treat highly polluted industrial waste or to mitigate the risk of landslides that can affect entire districts.
