Why Vetiver?

Althouh many rasses and treeshave been tried over the years asmeasures to !revent erosion, to dateonly Vetiver rass has stood out.



+easons.

%ti and erect sterns, which formdense hedes, can stand u! torelatively dee! water ow whichreduces ow velocity and tra!ssediment.

t has a stron /brous root system

that !enetrates and binds the soil toa de!th of u! to $ meters and canwithstand the eects of tunnelin

and crac0in.



t is !erennial and re1uires minimalmaintenance.

t is both a 2ero!hyte and ahydro!hyte, and once established itcan withstand drouht, ood, and lon!eriods of water loin.

Hihly tolerant to a rowin mediumhih in acidity, al0alinity or salinity.

t will row in all ty!es of soil te2tures3

this includes sand, shale, and ravel. ts leaves and roots have demonstrated

a resistance to most diseases.



t will row in a wide rane ofclimates. t is 0nown to row in areas

with averae annual rainfall between455 and 6,555 millimeters and withtem!eratures ranin from -7" de 8to "" de 8.

Hihly tolerant to A, )n, 9i, :n in thesoils.

t is chea! and easy to establish as a

hede and to maintain.



How it Wor0s?

When !lanted, the rass 1uic0ly forms adense !ermanent hede which will reducewater ow velocity.

(he cano!y of rass will reach a heiht of4 meters in a s!an of # months, whichchanes direction ; ow of water velocity.

t has sti and erect stems which canstand u! to relatively dee! water ow. tsshar! leaves and aromatic roots re!elrodents, sna0es and similar !ests.



+oot lenth reaches # meters in $ years. ts stron /brous root system !enetrates

and binds the and can withstand theeects of tunnelin and crac0in.

When roots interact with the soil it formsa dense matri2 of roots with the roots

around it hence increasin (ensilestrenth.

+oots are very stron with hih meantensile strenth of <" )Pa or 7=6th of

strenth of mild steel. t is !erennial and re1uires minimal

maintenance.
