In the 80's, Embrapa (same research agency) discovered a way to grow Soy in the Midwest/cerrado... And that's how today Brazil is the largest soy exporter in the world. Before the 80's, soy was only grown in the South of Brazil (and Brazil imported soy at the time as I recall). Currently, wheat is also only grown in the South as well. Now, things are not simple. The wheat prices will need to be competitive to make farmers plant wheat instead of only soy. Soy currently totally dominates Brazilian farming. Everywhere you look you only see soy. PS: Embrapa is also developing several varieties of grapes for Cerrado/Midwest region. Currently it's basically only grown in the South as well.
