Abstract

A sample of Clarion loam soil taken near the U. S. Gypsum Co. plant at Fort Dodge, for which the owner claimed accumulated injury from dust deposits, showed no symptoms of high -Ca injury. Potted crop plants growing in the soil showed marked response to nitrogen and phosphorus added together, little or no response to potassium added alone to balance excess calcium ions, and responded positively to additional applications of gypsum at the rate of 100,000 pounds an acre.
