The pH scale measures how strongly acidic or alkaline a solution is using a set of values from pH 0 to pH 14. When pure water is dropped into a solution of universal indicator, the indicator stays ...

Soil pH is defined as the negative logarithm of the hydrogen ion concentration. The pH scale goes from 0 to 14 with pH 7 as the neutral point. As the amount of hydrogen ions in the soil increases the ...

This number between 0 and 14 can be the difference between nutrient-dense soil ... If the pH registers higher than 7.5, the soil is considered alkaline. Less than 7 on the pH scale means you have ...
