Longevity of Soil Reaction Effects Following Lime and Alum Additions1

T. B. Hutcheson, Jr. and J. F. Freeman2

Synopsis: Effects of lime and aluminum sulfate on pH were quite pronounced 6 weeks after application, but had diminished in 12 months and changed little during an additional 24-month period. Three years after applications, little effect was evident on pH, exchangeable acidity, Al, Ca, or Mg below 8 inches. Exchangeable Al levels were less than 1/100th of those actually applied, indicating that hydrolysis and precipitation of Al as some species of aluminum hydroxide had occurred.

1 The investigation reported in this paper (No. 64-3-40) is connection with a project of the Kentucky Agricultural Experiment Station and is published with approval of the Director.

2 Associate Professors of Agronomy. (Senior author now Professor of Agronomy, Virginia Polytechnic Institute, Blacksburg.
