Hi,
I had an interesting meeting this morning with someone who is extracting
oil from the marula nut (Scelerocarya birrea). Have a look at
www.marula.org.za for more information on this - google it and you'll
find a whole lot of other really good info. Apparently you can get 10
trees/ha, 2000tpa/ha of fruit, 30% of which is nut and 25% of nut is
oil, this is hearsay and needs to be confirmed (anyone got a
reference?). They are indigenous and all over the Limpopo Province, the
fruit pulp (used for brewing a form of beer, gives me a headache) is
prized above the nut, although there is a market for the oil. It may be
a better option compared with Jatropha - you could probably get the oil
by tomorrow. I'm going to get some and make a few test batches.
Regards,
Duncan
