Soil pH is a measure of the relative acidity or alkalinity of a soil. While the scale goes from 0 to 14 (with a neutral pH represented by 7.0) most agricultural soils have pH values of between 5.5 and 7.5. The pH scale is logarithmic; that is a pH of 5 is ten times more acidic than a pH of 6. The natural
