A Case Study of Effects of Acidic Air Pollutants on Crop Yields
The purpose of the study was to determine the risks to agriculture of current levels of pollution by evaluating the effects on farm yields. The study examines the effects of air pollution (sulfates and nitrates) and acid rain on two major crops: corn and soybeans, using a natural (as opposed to controlled) experimental approach. At the site, crops are exposed to varying treatment levels, and multivariate statistical analysis is used to isolate the effects of pollution on cropland yield variation. The report identifies data sources, methodological problems, and makes conclusions for future research.
