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.
