Decarbonise the Air, Recarbonise the Soil!
More than a third of farmland in the U.S. Corn Belt — nearly 100 million acres — has completely lost its carbon-rich topsoil due to erosion, according to a new study published in the journal Proceedings of the National Academy of Sciences. The loss of topsoil has reduced corn and soybean yields in the Midwest by 6 percent, resulting in a loss of nearly $3 billion a year for farmers, and increased runoff of sediment and nutrients into nearby waterways, worsening water quality.
