Excerpt from The Growth of Wheat Seedlings as Affected by Acid or Alkaline Conditions A few years ago Director Thorne, of the Ohio experiment station, called the attention of one of the authors to peculiar conditions exist ing on certain of his fertilizer experiment plots, to which potassium chlorid and potassium sulphate had been applied annually for the past 12 years. These plots had become so acid that, it was found impossible to grow clover on them. Liming one-half of each plot had restored that half to almost its original fertility. This acidity, he said, was due to the selective action of the root, doubtless a correct explanation which will be considered in detail later.
