Soil Acidity and for Agronomic Production Ohioline

pH is a measure of the hydrogen (H +) ion concentration in solution.Due to the way pH is calculated, the higher the hydrogen concentration, the lower pH becomes. A pH value below 7.0 is considered acid and, depending upon the soil pH and the crop being grown, may require neutralization to raise the soil pH.

The buffer index is arrived at by adding a chemical solution of a known pH (called a buffer) to the soil distilled water solution after the initial pH measurement is taken. The amount of change in pH of the soil distilled water solution after the addition of the buffer solution measures a given soil's reserve acidity, or buffering capacity.
