Measure pH in soil

The acidity of the soil can be determined with every pH meter. This can be done in the following way:

To measure the pH value of a soil sample, the following method is often used:

1. Take a soil sample. This can be done with a soil drill or a scoop. Collect the soil from as many places as possible to get a representative sample.
2. Collect the sample in a bowl and determine if it contains the correct amount of moisture. The soil has the right humidity when there is moisture between the fingers if it is squeezed.
Apply the soil to the correct moisture content by administering demineralised water until moisture disappears between the fingers. Mix the soil well after administering the water.
3. Then take a 250 ml measuring cup and fill it with 150 ml demineralised water. Add earth to 250 ml. Mix thoroughly and let it rest for at least 2 hours.
4. Mix again thoroughly and measure the pH value of this mixture.

In fact, the soil is diluted with a pH neutral liquid (demineralised water) and the pH value of this mixture is measured. Most people skip step 2 because it is
the effect of this on the measuring result is usually not so great. However, this will have to be established experimentally in every situation. The most important thing about the procedure, however, is that there is
demineralized water is used.
