   Wow, the computer sure screwed up that chart and I don't have a 'Word' 
program on this computer so I guess I'll have to wing it.

Here is one I found online for changing pH to 4.5, ideal for growing 
blueberries, assuming a start pH of 7.0:

Table 1 Changing Soil pH with Sulfur

     pH of soil Sulfur (lbs. per 100 sq. ft.)
     Soil Type
     Sand Loam
     4.5
     5.0 0.0
     0.4 0.0
     1.2
     5.5
     6.0 0.8
     1.2 2.4
     3.5
     6.5
     7.0 1.5
     1.9 4.6
     5.8


I think it is straight-forward enough; if your soil pH is 6.5 and you have 
loam, you need to add 4.6 pounds of sulfur per 100 sq. Feet to attain a pH 
of 4.5.  Bear in mind, though, that you won't get an instant reaction.  Soil 
bacteria need to do the work and it will take months before the goal is 
achieved.  The chart I sent before, the one that the computer screwed up 
called for pints of sulfur per 100 sq. ft.  and/or pounds per acre.  If you 
need that information, ask and I'll see what I can do.

Someone else asked for help elevating pH.  I don't know where to find a 
chart for that.  This is the best I can do without sending another chart for 
the computer to screw up.  The amounts are pounds of calcium carbonate - If 
dolomite is used, add 12%:
   To change pH 4.5 to pH 5.5 - add 25 lbs. for sand or loamy sand, 45 lbs. 
for sandy loam, 60 lbs. for loam, 80 lbs. for silt loam, 100 lbs. for clay 
loam and 200 lbs. for muck.
   To change pH 5.5 to pH 6.5 - add 30 lbs. for sand or sandy loam, 55 lbs. 
for sandy loam, 85 lbs. for loam, 105 lbs. for silt loam, 120 lbs. for clay 
loam and 225 lbs. for muck.

   That's the best I can do without getting really involved or doing more 
work than I have time for.  Hope this all helps.  If anyone needs my first 
chart, I could send it to you via snail mail.
