The degree of acidity/alkalinity of a solution is identified on the ph scale of 0 to 14, with a pH of 7 representing the neutral point. The pH scale is logarithmic, meaning small changes in pH represent large changes in the degree of acidity or alkalinity. For example, a solution with a pH of 5 is ten times as acidic as a solution with a pH of 6, but a solution with a pH of 5 is 100 times as acidic as a solution with a pH of 7. The pH of the nutrient solution is a major determinant of nutrient uptake by the plant.
