We also will send sorghum to be bred with local varieties and tested in Ethiopia, Mali, and South Africa, where it is a major food crop. 6 Land Institute shorts Study of whether cereal crops might fix nitrogen. Gifts of land. Talking about perennial grains to the UN’s food and agriculture arm. New board members.
