2. The role of pH in agriculture

In agriculture, pH represents the quality of the living environment of organisms such as plants, animals, etc. Every plant and organism has a suitable pH range for the best growth and development. If the pH is not within that range, it will affect their ability to absorb nutrients and essential elements needed for their growth.
