"D ECENT work by Arnon and associates (1, 2) has -'-*shown that acidity greater than that usually found in acid soils is not directly injurious to plant growth. These investigators found that normal plant growth could be obtained at pH 5.0 in nutrient solutions containing 280 ppm calcium. Therefore, it would appear that the high amounts of calcium found in many acid prairie soils should be sufficient for normal plant growth and that poor growth of legumes occurring on these soils might be due to other injurious factors.
