TWO REMARKABLE innovations have enabled Brazilian farmers to compete with the soy and corn exports of their US counterparts—breeding soybean varieties for low latitudes using biological nitrogen fixation (BNF) (Hungria, Campos, and Mendes 2001; Alves, Boddey, and Urquiaga 2002; Dobereiner 1997) and the adaptation of a double-cropping soy-corn system for production in the savanna.
