Alkaline soils are defined as soils having a pH greater than 7. High content of base cations like sodium and calcium contribute to a higher pH, leading to alkaline conditions. Sodic soils (high sodium) and calcareous soils (high calcium carbonate) are common types of alkaline soils. Statement 2 is correct. Black cotton soil (Regur soil) is characteristic of the Deccan Trap region in India and is formed from the weathering of basaltic lava rocks under conditions including high temperatures and distinct wet and dry seasons, which facilitates the formation of expansive clays and cracking. Statement 3 is correct. Laterite soils are formed through intense weathering and leaching in hot, humid climates with distinct wet and dry seasons. This process, called laterization or desilication, involves the removal of silica and bases, leaving behind a concentration of iron and aluminum oxides in a deep weathered layer.<br \/>\n<\/section>\n<section id=\"pyq-key-points\">\nSoil classification and properties are influenced by parent material, climate, topography, organisms, and time.

Black soils are known for their high clay content and moisture retention but can be difficult to cultivate when wet or dry. Laterite soils are often poor in nutrients due to intense leaching but can be used for crops like cashew, tapioca, and groundnut after appropriate management.<br \/>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Consider the following statements regarding soils: 1.
