Acid soil
Acid Soil
Acid soil (pronunciation: /ˈæsɪd ˈsɔɪl/) is a type of soil that has a pH value of less than 7.0.
Etymology
The term "acid soil" is derived from the Latin word "acidus", meaning sour, and the Old English word "sweor", meaning earth or ground.
Description
Acid soils are typically rich in iron and aluminium compounds, and have a low concentration of calcium and magnesium. They are often associated with high rainfall areas, as the excess water leaches away basic ions such as calcium and magnesium, leaving the soil acidic.
Effects
Acid soils can have a detrimental effect on plant growth, as they can limit the availability of essential nutrients and increase the solubility of potentially toxic elements. However, some plants, such as rhododendrons and blueberries, are adapted to grow in acid soils and can thrive in these conditions.
Management
The acidity of soil can be managed through the application of lime or other alkaline materials, which can neutralize the acid and increase the pH. This process is known as liming.
