   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. Cation-exchange capacity - Wikipedia

   en.wikipedia.org/wiki/Cation-exchange_capacity

   Cation-exchange capacity (CEC) is a measure of how many cations can be retained on soil particle surfaces. [1] Negative charges on the surfaces of soil particles bind positively-charged atoms or molecules (cations), but allow these to exchange with other positively charged particles in the surrounding soil water. [2]

   Structure liming can reduce losses of clay and nutrients from soil aggregates. [3] 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 ...

7. Acid neutralizing capacity - Wikipedia

   en.wikipedia.org/wiki/Acid_neutralizing_capacity

   Acid-neutralizing capacity or ANC in short is a measure for the overall buffering capacity against acidification of a solution, e.g. surface water or soil water.. ANC is defined as the difference between cations of strong bases and anions of strong acids (see below), or dynamically as the amount of acid needed to change the pH value from the sample's value to a chosen different value. [1]

8. Base-cation saturation ratio - Wikipedia

   en.wikipedia.org/wiki/Base-cation_saturation_ratio

   Base-cation saturation ratio (BCSR) is a method of interpreting soil test results that is widely used in sustainable agriculture, supported by the National Sustainable Agriculture Information Service (ATTRA) [1] and claimed to be successfully in use on over a million acres (4,000 km 2) of farmland worldwide.
