What is Acid Soil?
Acid soil is soil which has a low pH, indicating that it is on the acidic side of neutral. Gardeners can determine soil pH with home testing kits, or by sending samples to labs which service gardeners, and determinations of soil acidity are a very important part of gardening, because plants respond to changes in soil acidity or alkalinity. Some plants prefer acid soil, while others like a more neutral or alkaline environment, and soil conditions can be an important limitation to think about when gardening. Soil pH tends to range between five and eight, with five being very acidic for soil. A number of things can influence the balance of the soil, including the compounds present in the soil and amendments added by a gardener, ranging from sand to fertilizer. It is possible to deliberately adjust the pH level of soil to meet the needs of specific plants. Plants which thrive in acid soil need acidic conditions to live. If they are grown in neutral or alkaline soils, they may not be able t
