What is pH? What is its range? What are the negative impacts if the pH of soil is too low or too high?(AS1)
pH- pH is the amount of the hydrogen ions present. The term pH is used to indicate the level of acidity or alkalinity of a soil.
The range of pH lies from 5.5 to 7.5. (good soil).
Below pH 7 the soils are termed as acidic and,
above pH 7 the soil are termed as alkaline.
If the pH of the soil is too low (decreasing pH) that means soil contain more acid (acidic) and acidic soil results in the removal of the important nutrients or in decreased microbial activity.
If the ph of the soil is too high that means soil contain more bases (alkaine) and basic soil do not promote cultivation.
