George Washington Carver was honored by the United States with a stamp twice. Once in 1948 and again in He discovered and taught farming techniques that are still used today.
He told poor farmers to use swamp muck instead of fertilizers. What did this add to the soil?
He told farmers who had grown cotton in the same fields for many years to switch to peanuts or soybeans for a few years to replenish the soil. What is this called?
He is best known for all the uses he developed for the peanuts. He testified before Congress in 1921 to ask for a tariff on imported peanuts to protect the American crops. How would that help? (Social Studies connection!)
enrich croplands with swamp muck instead of fertilizers.
His idea of crop rotation proved to be most valuable.
Through his work on soil chemistry, Carver learned that years of growing cotton had depleted the nutrients from soil, resulting in low yields. But by growing nitrogen-fixing plants like peanuts, soybeans and sweet potatoes, the soil could be restored, allowing yield to increase dramatically when the la
