Distribution of Magnesium Fractions in the Nilgiris Soil Profiles: II. Distribution in Typic Palehumults

Abstract

In most of the profiles, the total Mg and the magnesium fractions were either consistent throughout the profile or gradually decreasing with depth. In most of the Instances organic cycle was present. Reserve (ecid-solublo) magnesium was observed to be get released during weathering. In Doddabetto soils ndoquete amounts of reserve magnesium was present even In the sub-soil Indicating the presence of basaltic parent materials. This needs further study. Clay pan was precont in Ward's Gate profile characterised by accumulation of total Mg and its various fractions, associated with high clay.
