Can lime be used with soils containing soluble sulfates?
Particular attention must be paid to the sulfate content of soils when considering lime stabilization. Caution must be used when using lime or any calcium-based stabilizer with soils containing more than 10% clay and 0.2% soluble sulfates when the sulfates are extracted from the soil in a 10 parts water to 1 part soil solution. For more information, see Technical Memorandum: Guidelines for Stabilization of Soils Containing Sulfates available from the National Lime Association www.lime.
