Soil pH or soil reaction is an indication of the acidity or alkalinity of soil and is measured in pH units. Soil pH is defined as the negative logarithm of the hydrogen ion concentration. The pH scale ...

pH is a measurable parameter between the values of 0 and 14, defining the acidity or alkalinity of a solution. Solutions with a pH = 7 are considered neutral, pH < 7 are considered acidic and pH > 7 ...

Soils collected across a long-term liming experiment (pH 4.0–8.3), in which variation in factors other than pH have been minimized, were used to investigate the direct influence of pH on the abundance ...

The pH scale is used to measure the acidity of a fluid. The pH scale ranges from 0 to 14. A pH of 7 is neutral, whereas a pH result below 7 is acidic and above 7 is alkaline. Urine has the widest ...
