A friend in the Peace Corps in central Africa writes me, says he is
trying to research mulching techniques and how they may be useful in
the sahel region. The peace corps books don't really seem to mention
mulch and he wants to add it to the manuals. I'm guessing that some of
you have been there. If anyone has knowledge or suggestions, please send
them along and it will be much appreciated!

many thanks,

The conditions are as follows:

Materials available locally:
Shrubs, many from the mint family, some grasses, mango leaves in
abundance, several varieties of acacia, and cassia, neem trees,
eucalyptus trees, sesbanias, peanuts (plants and shells), corn stalks,
coos stalks, rice plants, and sawdust (lumber mill about 6 miles away

Seasonality and rainfall regime:
Two seasons, wet and dry. The wet season is pretty much finished and it
will probably not rain again for about 6 months. Temperatures range
from 80-100+, and there is a strong Harmattan wind that blows in

Water sources:
Wells, about 40ft deep, and sometimes closed with a pump, sometimes
open.
irrigation is done by hand, normally

Main crops grown:
Mostly coos, and rice, with some corn. Right now, they are no longer
working the farms, have stored their coos, and are working on
establishing gardens where they will plant tomatoes, okra, hot pepper,
eggplant, bitter tomatoes, lettuce, cucumber, watermelon, and onions.
Volunteer is hoping to also push carrots, sweet pepper, and maybe even
garlic, any reason not to?

Livestock:
Cows, sheep, and (highly destructive) goats. Some families have
chickens. All animals, except cows, are free range and go "wherever the
hell they
please"

Serious insect problems or poisonous critters around?
Termites, grasshoppers, aphids, ants, moths, caterpillars, beetles,
scorpions, and puff adders.

Cooking fuel sources currently in use?
Mostly firewood (from a disappearing forest) and charcoal, with a few
well-off people using gas.
