Which African American scientist is known for his work with peanuts and crop rotation?

George Washington Carver is renowned for his pioneering work in agriculture, particularly his innovative practices involving peanuts and crop rotation. In the early 20th century, he emphasized the importance of crop rotation, which helped restore nitrogen to the soil, thereby improving the quality of land depleted by cotton crops. He promoted the planting of peanuts, sweet potatoes, and other legumes as alternative crops, which not only enhanced soil health but also provided farmers with new sources of income and food. His research significantly advanced agricultural science, transforming farming practices in the southern United States and contributing to greater sustainability in agriculture.

In contrast, Benjamin Banneker was notable for his work as a mathematician and astronomer, Garrett Morgan was an inventor known for his contributions to safety and traffic management, while W.E.B. Du Bois was a significant civil rights activist and sociologist. None of these individuals focused on agricultural science to the extent that Carver did, particularly concerning peanuts and crop rotation.
