In the late 19th and early 20th centuries, Southern agriculture faced significant challenges, including soil depletion due to monocropping and economic hardships among farmers. George Washington Carver, an agricultural scientist and educator at Tuskegee Institute, addressed these issues with innovative solutions. His deep curiosity about plants led him to develop crop rotation methods, promoting the cultivation of soil-enriching crops like peanuts and sweet potatoes alongside cotton. This practice restored soil fertility and provided farmers with alternative cash crops, reshaping Southern agriculture and improving the livelihoods of many. (invent.org)

8. Cheap, Nutritious Synthetic Rubber

During World War II, shortages of natural rubber prompted George Washington Carver to collaborate with Henry Ford to develop a synthetic alternative. They experimented with various plants, including peanuts, sweet potatoes, and goldenrod. Their work led to the creation of a rubber substitute from goldenrod, a common weed. Although this innovation was not commercially adopted at scale, it laid the groundwork for future developments in biodegradable plastics. More details on Carver’s wartime experiments are available at the Library of Congress: loc.gov
