Acidic soils have a pH value below 7, indicating high acidity, not alkalinity. A pH value below 7 indicates increasing acidity as the value decreases. Lime, in the form of calcium carbonate or other alkaline materials, can be applied to acidic soils to raise the pH and reduce acidity. This process is known as liming and is done to adjust soil pH for optimal plant growth. Soil pH influences nutrient availability in the soil. Different nutrients have varying solubilities at different pH levels, affecting their availability to plants. Additionally, soil pH also influences microbial activity, as different microorganisms have different pH preferences for optimal growth and function.
