PH is most important in agriculture

In agriculture, the pH of the soil shows what crops will grow easily in the soil and what adjustments are needed to adapt it for growing other crops.

Acidic soils are often considered infertile as the solubility of aluminium and manganese also increase with acidity. However, conifers and members of the family Ericaceae, such as blueberries, prefer acidic soils. Acidic soil can be neutralized by treating it with lime.
