The proper notation is Small p with a capital H. The capital H stands for the element of Hydrogen and the small p is a math notation for inverse change.

What is pH?? It is the measurement of the acidic or alkalinity of a SOLUTION by the measurement of the inverse logarithm of the Hydrogen ion. Because it is the INVERSE LOGARITHM of the Hydrogen Ion the larger the pH value the Less Hydrogen ions and of course the lower the pH value the more Hydrogen Ions. A pH of 6 will have 10 time the number Hydrogen Ions as a pH of 7.

A simple $ 19.00 pH meter and pH up (Phosphoric acid) and pH Down (Bicarb) solves any problems of pH effecting the efficacy of a pesticide.

BTW most Whole Milk is 6.5 pH and can be used as a calibration for a pH meter.

pH reading of soil done in professional labs can vary greatly on the same sample. Since pH is the Measurement of Hydrogen Ions in a solution a solution must be added to the soil. Which MOLE SOLUTION is used will effect the number of hydrogen ions released in that sample. Therefore always use the same lab or same method and Mole solution when comparing soil sample history.
