Adding lime to acidic soils primarily raises the soil pH, making the environment less acidic. This adjustment in pH is critical because many nutrients become more available to plants when the pH is within an optimal range (usually around 6 to 7). In highly acidic soils, nutrients such as phosphorus, calcium, and magnesium may not be readily accessible to plants, leading to deficiencies that can affect plant health and growth. By increasing the pH through liming, these nutrients become more soluble and thus more available for plant uptake.

In addition to improving nutrient availability, lime also helps to mitigate toxicities from elements like aluminum, which can become problematic in very acidic conditions. Overall, liming is an essential practice in soil management to enhance crop production and maintain soil health in acidic soils.
