Ozone's impact on soybean yield: Reducing future losses

Ozone is a pollutant that damages crops, particularly soybean. Researchers have investigated the responses of seven different soybean genotypes to eight ozone concentrations. The plants were exposed to ozone concentrations ranging from ambient levels of 38 parts per billion up to 200 parts per billion. They found that any increase above the ambient concentration was enough to reduce seed yield: roughly half a bushel per acre for each additional part per billion.
