Soil acidity is determined by a measurement of the hydrogen ion concentration of a particular soil. A pH meter is the instrument generally used by soil testing laboratories in measuring soil acidity. Generally, a small portion of the soil sample is mixed with water in a 1 to 1 or a 2 to 1 ratio and stirred. After the soil solution has set for approximately 30 minutes, a glass electrode and reference electrode are dropped into the soil-water mixture and the soil pH is determined. The measurement scale used in determining soil acidity is the pH scale which ranges from 0-14. A soil pH of 7.0 indicates a soil is neutral in reaction. Any number below 7.0 denotes soil acidity and numbers above 7.0 denote soil alkalinity. These measurements are a logarithmic factor. Therefore, a soil with a pH of 6.0 is 10 times more acid than a soil with a pH of 7.0. A soil having a pH of 5.0 is 100 times more acid than a soil pH of 7.0, etc.
it raises soil acidity pH
As in all acid-base (alkali) reactions, it will reduce the acidity of the soil and, if there is an excess of base to acid, it can make the soil become alkaline. The soil will be less acidic if base is less than acidity, become neutral (if base = acidity), or become alkaline if base is greater than acidity.
If the acidity of soil is too high, the germination of a seed will either be slowed or the seed may not grow at all. Some plants are very sensitive to the level of acidity in the soil and need to be treated carefully.
Most commonly limestone is used to decrease acidity.
Crushed limestone is added to soil to reduce its acidity.
Acidity (and other) tests for soil are best done by professionals. Usually, a county or parish will have an agricultural extension agent who can give you information on how to collect soil samples, and where to deliver them for testing.
The acidity of the soil. Some plants like more acidic soil while others prefer more alkaline. By measuring the pH, you are able to adjust the soil's acidity accordingly.
