GENERAL KNOWLEDGE

Detailed explanation-1: -If the soil is acidic in nature, it not only decreases the solubility of minerals but also affects the availability of the nutrients. Thus, for converting the acidic soil into neutral soil, a small quantity of quicklime or slaked lime solution is added. Lime is alkaline in nature, which will neutralize the soil.

Detailed explanation-2: -Lime (calcium carbonate) and other liming sources such as dolomite (magnesium carbonate) reduces soil acidity by neutralizing acid reactions in the soil. The carbonate component reacts with hydrogen ions in the soil solution and in doing so raises the soil pH.

Detailed explanation-3: -In order to reduce the alkaline effect of the soil, decaying organic matter is added. Organic matter releases acids when they decay, which can counter balance the alkaline nature of the soil.

Detailed explanation-4: -Soil treatment with quicklime or hydrated lime is a well-known and extensively used technique for earthworks to dry up wet soils and to enhance their performance.
