What is pH?

• pH is nothing more than a chemist's shorthand for
  describing the amount of hydrogen in products
  The capital letter "H" is the chemical symbol for
  hydrogen and pH is a figure describing the
  concentration of hydrogen in the product, which
  in turn determines the acidity of the product.

pH and Plants

• Soil pH is very important because it influences
  several soil properties that directly affect
  growth of plants. Soil pH effects soil bacteria
  and nutrient leaching and availability.
