1. Agricultural Innovations: The Three Sisters
One of the most enduring Indigenous contributions is the Three Sisters agricultural system. By planting corn, beans, and squash together, Native farmers created a sustainable method that maximized land productivity and improved soil health. Corn provided a structure for beans to climb, beans fixed nitrogen in the soil, and squash spread along the ground to conserve moisture and deter pests. This ingenious system not only fed communities but also shaped American farming practices for generations. Source
