Effect of Soil Acidity on Establishment and Growth of Orchardgrass Seedlings in Pot Cultures1

  1. E. F. Sullivan and
  2. L. F. Marriott22



Establishment of orchardgrass, as determined by yield of top-growth, was most rapid at pH 6.7. Herbage quality was improved by the addition of lime to soil testing pH 4.7. Root weights decreased with increasing pH levels above pH 5.3. Pennlate orchardgrass did not become established at pH 4.7; but, the addition of 1 ton of lime per acre (pH 5.3) overcame this adverse condition.
