    thats for Ph correcting water.

    i know a few people that use dolomite lime to help with soil Ph problems.

    To lower ph in soil: Phosphoric acid, vinegar, lemon juice, sawdust, composted leaves, wood chips, cottonseed meal, leaf mold, peat moss, or PH Down.

    To raise pH in soil: potassium hydroxide, dolomite lime, hardwood ash, bone meal, crushed marble, crushed oyster shells, or PH Up.
