GANGETIC ALLUVIUM OF INDIA

Abstract
Three major soil types were recognized. The soil types are differentiated primarily by the degree of Ca leaching. All the soils are developed on calcareous parent material. Type 1 occurs in the lowlands and contains large reserves of lime throughout the profile. Type 2 occurs at higher levels and contains excess lime in the form of CaCO3 nodules at the bottom of the profile only. Type 3 occurs in the uplands and contains no free lime. Detailed mechanical, chemical and physiochemical data on the 3 types of soil are presented.
