GENERAL KNOWLEDGE

Detailed explanation-1: -The laterite soil develops in areas with high temperature and heavy rain. This is the result of intense leaching due to heavy rain. Humus content of the soil is low because most of the micro organisms, particularly the decomposers, like bacteria, get destroyed due to high temperature.

Detailed explanation-2: -The laterite soil is formed under conditions of high temperature and heavy rainfall with alternate wet and dry periods, which leads to leaching of soil, leaving only oxides of iron and aluminum. It lacks fertility due to a lower base-exchanging capacity and a lower content of nitrogen, phosphorus, and potassium.

Detailed explanation-3: -Laterite soil is formed as rain-induced leaching.

Detailed explanation-4: -Laterite soil is rich in aluminum and iron, formed in wet and hot tropical areas. Almost all laterites are rusty red due to the presence of iron oxides. It is prepared by the long-lasting and intensive weathering of the parent rock.
