Question

What can we do if soil is
i) too acidic
ii) too basic​

Answer 1

Acidic

If soil acidic too much

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

Basic

To improve the quality of a basic soil, an acid should be added. Slaked lime (Ca(OH)2) and quick lime (CaO) are basic in nature. Urea is neutral. Hence, organic matter is the answer.
