Alan:

     For a few seasons I used a liquid formulation of calicum and it did NOT drive up the pH (at least to a point of where there was a problem mixing pesticides with it).

     The single reason why I quit using it is that I found that foliar applications of CA did little good in many seasons (especially those which had more than normal rain/less sunlight).  Or an annual ground application of pelletized CA (late fall applied or very early spring) worked much better in dealing with related deficiencies.  And it is relatively inexpensive.

ed....hope this helps

Dennis, thanks but my question still lingers.  Anyone else know if these sprayable calciums drive up the pH of the spray mix?  I could do a test myself but I have no sprayable calcium.  Also, stating that a cup of vinegar per 100 gallons is an exceptable buffer is pretty unspecific, especially coming from you (that's what you get for establishing such high standards by way of your much appreciated input).  Commercial buffers provide precise info about how much to use to lower pH from level to another.
