The latifundia-style plantations almost always have one crop on them. In general, in the past, there were three types of plants that have been used for the latifundia-style plantations, grains, grapes, and olives, and they were all products that were planned for export. The latifundium is a very large, and very expensive parcel of land. It was privately owned by one very rich person.
