Detailed explanation-1: -What Happens If Soil Is Too Alkaline? High pH levels typically hinder plant growth, especially with plants that do best in acidic soil like blueberries, rhododendrons, and azaleas. Soil alkalinity indicates a higher calcium carbonate content that produces chalky, highly porous soil.

Detailed explanation-2: -Soil acidity can be corrected easily by liming the soil, or adding basic materials to neutralize the acid present. The most commonly used liming material is agricultural limestone, the most economical and relatively easy to manage source. The limestone is not very water-soluble, making it easy to handle.

Detailed explanation-3: -If the soil is too acidic then lime is added to soil to increase its pH and to reduce it acidity.

Detailed explanation-4: -Plants cannot grow if the soil is too acidic or too alkaline. If soil is too acidic then lime can be added to neutralise it since lime is basic in nature. But if the soil is alkaline in nature then organic matter should be added and not lime.
