Dolomite etc will Raise pH etc However to change EC is a much harder and expensive to do. Bio Carbons will effect surface tension and Hydraulic conductivity. High EC (Electric Conductivity) or Measurement of soluble salts in a solution, will fill exchange sites and cause Fertilizer or pesticide leaching. Therefore pH of water is the least of our problems.

Basically the pH chart given only tells us what pH range most all element are available in the greatest quantity. Once we know 6.5 is approx that magic point on the pH scale, the chart above is really of no use.

But it's purdy...
