      from  Lewis L Smith

Vetiver really works. We planted some pigeon peas on a 35 degree slope 
on our farm in Puerto Rico for years, with a row of vetiver [ pacholí ] 
planted on the contour, above and below the planting of peas. Never had 
any problem with erosion. However, vetiver should not be allowd to 
reach its maximum height but cut back every so often.

The URL given by B Jatta not only has pictures but manuals based on 
extensive experience with vetiver in agricultural and conservation 
uses, especially in the prevention of eroison, espcially in Asia. This 
is one "wheel" which definitely doesn't have to be invented or proven.

Using vetiver is also a great way to save diesel and No. 6 fuel oil, in 
protecting railroads, roads, stream embankments and such like. It can 
completely replace en engineering works.

Cordially. ###

Hi Bakary,
 
Thank you for sharing the www.vetiver.org site.  That
first picture with the 3 meter roots is just amazing! 
It is easy to see that the Vevitar Grass is very effective at erosion
control.  I liked the side view picture too, of the site 4 slope in
Malaysia, which was turned into a terrace in 30 months.  That 
"Overview"
photo essay is a compelling visual introduction.
 
Regards,
 
SKB

Dear lou and list members,

If we link TP and
  sequestering CO2 with Agricultural systems, let us go a
step
further.
  Soil erosion is a major disaster world wide, especially when people
are
   trying to farm marginal lands on side hills and other problem sites. 
A

successful technology
introduced in many countries is the use of
  Vetiver grass to make low contour
bunds permanent. It is not invasive and
  is a survivor. It traps soil and
debris and breaks the force of run off
  water.
The grass has roots that penetrate soil to a depth of up to
three
  meters. It gets established within a short time and it probably
sequesters
  CO2 more effectively than several other plant species. Add some
biochar
  when planting to optimize the process right from the start and you
have
  added another plus to increased agricultural production. For more
  info
about the technology go to www.vetiver.org .

Kind
  regards,

Bakary Jatta
