Is Dust "Busting" Crop Yields?
We have long known that air pollution has a negative effect on plant growth. Dust deposits on leaves and higher ozone concentrations in fi elds result in smaller plants for many crops. Recent research on local climate change has shown that a class of air pollutants, called “aerosols,” may have a local drying and cooling effect. While cooler nights are good for many plants, these gains are possibly offset by decreased rainfall and solar radiation.
