-Hope this helps, this is what I found :)

Argentina can be split into 4 major sections, the Andes, the Patagonian plateau, the Chaco plain, and the central Pampas.

The Pampas, however, grow the majority of the food for Argentina, including its sheep, cattle, wheat, corn, soybean, and animal feed plants.
