Plants need specific types of soil to grow properly. When you have acidic soil and you need an alkaline or neutral soil, adding lime reduces the total acidity. However, you first need to know how the current level of acidity in the soil.By taking a test sample, you can find the soil's pH level.When tested, if the pH falls below 7, the soil is acidic, anything above 7 begins to become alkaline. Lime adds calcium and magnesium to the soil and counteracts the negative effects of a low pH.y taking a test sample, you can find the soil's pH level.
