Description:
An experiment was performed during the summer of 1982 to determine the effects of simulated acidic rain on seed yields on two commercial cultivars of soybeans grown according to standard agronomic practices. Plants were shielded from all ambient rainfalls automatically by two moveable exclusion covers and exposed to simulated rainfalls in quantities equal to the average amount of rainfall that occurs at the site. Seed yields of cv. Amsoy exposed twice weekly to simulated rain of pH 4.1, 3.3 and 2.7 were, respectively, 3.0,9.0, and 12.8% below yields of plants exposed to simulated rain of pH 5.6.
