Why is it said that the agricultural methods of the Aztecs were unique?

          From the floating fields called chinampas to the terrace crops grown, the Aztecs proved themselves to be much advanced as far as agriculture was concerned. The Aztecs mainly used four methods of agriculture.

          Prominent among them was agriculture using chinampas. Chinampas were often set up in lakes with the help of poles. The Aztecs overcame the lack of conventional farming land by chinampas. Each chinampa was framed by a group of up to fifteen people.

          The second form of agriculture was ‘rainfall cultivation’. The Aztecs also implemented terrace agriculture in hilly areas.

          In the valleys irrigation farming was used. Dams diverted water from natural springs to the fields. The Aztecs’ canal system was much effective. It was long enough to provide water to entire Aztec cultivations.
