Soil pH Effects of soil acidity Amazon S3. Soil acidity is measured by pH level which is the concentration of hydrogen ions in soil. A lower the pH level signifies a more acidic soil and a well maintained pH level will promote the quality of the soil as well as better crop productions., Soil acidity is neutralized by liming soils. Details on liming materials and liming practices can be found in Adams (1984). The general reaction that explains the interaction of a liming material such as CaCO 3 with water to form OH в€’ ions is (Thomas and Hargrove, 1984).

DEFINITION AND CAUSES OF SOIL ACIDITY Acid soils are defined as any soil that has a pH of less than 7.0 (neutral). Acidity is due to hydrogen (H+) ion concen-trations in the soil. The higher the H+ concentration, the lower the pH. It is also important to note that a one-unit Soil acidity is a crop production problem of increasing concern in central and eastern Oklahoma. Although acid soil conditions are more widespread in eastern Oklahoma, the more natural occurrence there has resulted in farm operators being better able to manage soil acidity in that part of the state.

    Soil acidity is measured by pH level which is the concentration of hydrogen ions in soil. A lower the pH level signifies a more acidic soil and a well maintained pH level will promote the quality of the soil as well as better crop productions. Another cause of soil acidity is the removal of plants. Most of plant material is slightly alkaline and contains nitrate ions. Once these plants are removed, the nitrate ions are released back into the soil and the slightly alkaline effect of the plant is removed hence the soil pH becomes slightly more acidic.
