One of the crops I found very beneficial, in Zimbabwe, was Comfrey. It produces
20 times more protein per acre than soybeans. It is a perennial, does well in
draught conditions, the roots work as a muti (medication), promotes strong
bones in young growing animals, and can be easily transplanted by cutting the
roots. Each plant produces 10 to 15 more plants. Will not tolerate chemicals
and is naturally resistant to pests.
If this is used in conjunction with raising chickens or pigs it is practically
sustainable since the manure from the animals feeds the crop and the crop feeds
the animals. It is also very good for humans. The USA FDA tried to debunk it
with one incidence of liver failure, without mentioning that the woman was on a
myriad of other drugs that cause many problems. It's funny how they missed that
in the public disclosures over concern for Comfrey.
