Products for Managing Soil pH
Shop lime, sulfur and related fertilizers or amendments used in programs for acidic or alkaline soil. Products differ in speed, nutrient contribution and the direction and degree of pH change.
How to Choose
Always test soil before adjusting pH. Match the material and calculated rate to the test recommendation; gypsum supplies calcium and sulfur but is not a general-purpose pH correction.
Browse products for high soil pH, low soil pH and soil testing.
