  • Understanding lime and gypsum better Trace and Save

    Lime and gypsum are broadly grouped as they are calcium-containing minerals which are used for soil amendment on agricultural soils. First, a note on how effective a specific source of lime is. There are two things that need to be considered in understanding the effectiveness of a specific lime source: 1) neutralising value and 2) fineness.
