It is a hard, white deposit that can be found in the topsoil or subsoil. Kankar can form when lime-rich water evaporates, leaving behind a deposit of calcium carbonate. It can also form when limestone or dolomite rocks weather down.<\/p>\n<p>Kankar can be a problem for farmers because it can make the soil hard and difficult to work. It can also reduce the amount of water that the soil can hold. However, kankar can also be beneficial because it can help to improve the drainage of the soil and reduce the risk of erosion.<\/p>\n<p>The other options are incorrect because:<\/p>\n<ul>\n<li>Option b) Weathering of rocks is not the main cause of kankar formation.
