Reduced soil tilling helps both soils and yields

Agriculture degrades over 24 million acres of fertile soil every year, raising concerns about meeting the rising global demand for food. But a simple farming practice born from the 1930’s Dust Bowl could provide a solution, according to new Stanford research. The study, published Dec. 6 in Environmental Research Letters, shows that Midwest farmers who reduced how much they overturned the soil—known as tilling—increased corn and soybean yields while also nurturing healthier soils and lowering production costs.
