Manual pH Meter

The pH meter is a simple tool that measures the pH levels in soil.

Preparation of soil:

  1. Remove topsoil to depth of 50mm.
  2. Use hand fork to loosen remaining soil, removing stones and other debris.
  3. Mix soil with water.

Preparation of meter:

  1. Lightly abrade probe but not tip, with fine abrasive paper.
  2. Wipe with cloth or tissue.

How to use it:

  1. Insert probe into soil with a twisting motion
  2. Leave for one minute
  3. Read dial on meter
  4. Remove and clean probe with clean cloth
  5. Prepare probe as previously described and repeat above by inserting the probe into a different but adjacent point to check the first reading.

Do not leave the probe in the soil for long periods.

  • A reading of 4 to 7 = acidic soil
  • A reading of 7 to 10 = alkaline soil

To reduce acidity apply 300g/m2 of ground limestone for every 1ph increase required. To increase acidity apply 70g/m2 of sulphate of ammonia.
