Soil acidity
Soil acidity is a measure of the hydrogen ion concentration in the soil solution, indicating whether the soil reaction is acidic, neutral, or alkaline.

Understanding soil acidity is essential for nutrient management. When soil pH is too low, essential nutrients become less available to plants, and the presence of toxic elements like aluminum increases, which can severely stunt crop growth.
Testing should be conducted prior to planting or fertilizer application to determine if liming is required. Lime materials are typically applied to increase the pH levels, with application rates determined by soil test recommendations.
A common error is the repetitive use of acid-forming fertilizers without soil monitoring. Another mistake is over-liming, which can induce micro-nutrient deficiencies, highlighting the need for precision based on actual lab data.
