How to use a soil pH meter

Shop for Soil pH Meters

In order to measure pH, the substance must be in a solution – this is why it is beneficial to add water and not rely on the moisture already in the soil.

Step 1 – Dig

Use a trowel to dig a small hole in the area you wish to test. This does not need to be deep; about the length of a trowel head.

Step 2 – Remove debris

Break up the soil in the bottom of the hole and remove any larger pieces, which may contain stones and leaves.

Step 3 – Add water

Pour some rain or bottled water into the hole and mix it with the soil using the trowel until you have a sludgy consistency.

Step 4 – Wipe and place tester

Wipe the pH meter probe with a cloth or kitchen towel and then place the tip of the probe into the muddy hole, so that it is submerged (approximately 5cm deep) and wait sixty seconds or so for the test to be effective.

Step 5 – Check indicator

When the needle or screen has settled, check the scale and take the value as your reading. Remember, seven is neutral, lower than seven is acidic, and higher than seven is alkaline.

Step 6 – Act on results

Now you know your soil conditions, you can choose the right plant for the environment, or if there is a plant that requires a change in conditions, you can do this accordingly.
