The optimum (target) pH for a soil depends on the crops that will be grown.  Once a desired pH is reached through liming, the pH will remain at that level for a relatively long time.  An exception to this is ___________________ soils which tend to need lime more frequently at lower rates.

Formulas are used to calculate lime requirements to bring soils to target levels.  The major variables used in these calculations is target pH for the crop, buffer pH (BpH) which is derived from a soil test, and the neutralizing index (which is unique to the liming material.)   Buffer pH indicates which of the following?
