they use it to neutralise acidic soil in fields
scientists use the ph scale so they can tell whether something is acidic or alkaline
you can use scale model to measure proportions
scientists use fajita scale to measure hurricane intensity
to verify the acidic and base e.g below 7 acidic and above 7 base.
A scale.
Richter Scale
PH is a measure of the acidity or alkalinity of the soil. Plants have a preferred range that varies from plant to plant: some prefer alkaline soils, some acidic. If an alkaline-loving plant is grown in acidic soil, it will not grow as well as it would in alkaline soil. Knowing the pH of the soil allows farmers to use chemicals to alter the pH and establish the best growing environment for their crops.
