Vetiver System and Coffee Production

I see that we have new members who are interested in using VS for supporting coffee production on steep land. For others who may be interested vetiver has proven very effective in Ethiopia for reducing erosion and rainfall runoff. Note like wine vetiver hedgerows improve their performance as they get older.   Coffee farmers, large and small, in Ethiopia indicate significant coffee yield increases.  Vetiver can be cut for use as coffee mulch.  In Zimbabwe it was noted that beneficial parasitic wasps used vetiver as a nesting habitat to the benefit of adjacent coffee.  Vetiver has been used for many years in Costa Rica, El Salvador and Guatemala to protect coffee plantation roads.  Vetiver could play an important role for "treating" polluted pulping waste from coffee factories.
