1.1 This test method covers the measurement of the pH of peat materials used as a growing medium. This measurement determines the degree of acidity or alkalinity in peat materials suspended in water and a 0.01 M calcium chloride solution. Measurements in both liquids are necessary to fully define the peat”s pH. This variable is useful in assessing the viability of the peat-plant environment. This test method does not apply to peat that is in paper or construction materials. Test Method D4972 is used for pH testing of soils and Test Method G51 is used for pH testing of soils for corrosion analysis (see Note 1).
Note 1: These three standards are being intentionally kept separate for clarity at the request of the various subcommittees.
