  2. Soil pH - Wikipedia

    Then, using the initial soil pH and the aluminium content, the amount of lime needed to raise the pH to a desired level can be calculated. [68] Amendments other than agricultural lime that can be used to increase the pH of soil include wood ash, industrial calcium oxide , magnesium oxide, basic slag (calcium silicate), and oyster shells.

  3. Liming (soil) - Wikipedia

    en.wikipedia.org/wiki/Liming_(soil)

    The degree to which a given amount of lime per unit of soil volume will increase soil pH depends on the buffer capacity of the soil (this is generally related to soil cation exchange capacity or CEC). Most acid soils are saturated with aluminum rather than hydrogen ions. Soil acidity generally results from hydrolysis of aluminum. [4]

  4. Agricultural lime - Wikipedia

    en.wikipedia.org/wiki/Agricultural_lime

    Some effects of agricultural lime on soil are: it increases the pH of acidic soil, reducing soil acidity and increasing alkalinity [1] it provides a source of calcium for plants; it improves water penetration for acidic soils; it improves the uptake of major plant nutrients (nitrogen, phosphorus, and potassium) of plants growing on acid soils.

  6. Soil acidification - Wikipedia

    en.wikipedia.org/wiki/Soil_acidification

    Soil acidification naturally occurs as lichens and algae begin to break down rock surfaces. Acids continue with this dissolution as soil develops. With time and weathering, soils become more acidic in natural ecosystems. Soil acidification rates can vary, and increase with certain factors such as acid rain, agriculture, and pollution. [1]

  9. Alkali soil - Wikipedia

    en.wikipedia.org/wiki/Alkali_soil

    Each unit decrease in pH indicates a tenfold increase of the H 3 O + concentration. Similarly, each unit increase in pH indicates a tenfold increase of the OH – concentration. In water with dissolved salts, the concentrations of the H 3 O + and the OH – ions may change, but their sum remains constant, namely 7 + 7 = 14. A pH of 7 therefore ...
