It is done because the soil acidity affects the growth of plants. It can be done by different methods.
Explanation:
The acidity of soil impacts its ability to support plant life. Generally, a somewhat alkaline (basic, non-acidic) soil is required.
A soil sample may be placed in a clean, deionized water bath. The soluble parts of the soil will go into solution and affect the pH (acidity value). The solution can be tested by using a specific chemical "indicator" - a compound that changes color at a specific pH value. It can also be tested with either an acid/base (Litmus) paper or a multi-range pH paper. It could also be analyzed with a calibrated pH meter.
