Abstract

In poorly drained humid portions of the glacial drift area of the eastern half of the United States occur certain unproductive organic soils which superficially resemble fertile loams. Analyses of these unproductive types generally disclose high acidity and mineral deficiency, especially of potassium. In many instances, however, lime employed to correct acidity, and potash to increase the nutrient value of the soil have proven injurious instead of beneficial to grain crops. The present investigation was undertaken to determine the explanation of the anomalous response and the exact nature of the injury.
