Before being a strategic commodity or a gear in the production of energy, protein, and food, corn is one of the oldest crops in human history. Originally cultivated by indigenous peoples in the Americas thousands of years ago, the cereal has traversed generations until consolidating itself as one of the pillars of modern agribusiness. In Brazil, this trajectory was even more surprising: from the base of family agriculture to the most advanced technologies in biotechnology, corn has transformed itself into an asset of food, energy, and economic security.
