Description : Soil which is prone to intensive leaching due to rain is called- (1) Laterite (2) Black (3) Alluvial (4) Red
Last Answer : (1) Laterite Explanation: Leaching refers to the loss of water-soluble plant nutrients from the soil, due to rain and irrigation. Laterite soils are formed soils under conditions of high temperature and heavy rainfall with alternate wet and dry periods. They are leached and are, thus, less fertile.
