Abstract

Six profiles from Naduvattam, Gudalur, Ootacamund, Nanjanad, Kotagiri and Coonoor of Nilgiris district in Madras State were studied for their profile morphology and physico-chemical properties. Detailed profile studies were conducted and the horizon-wise samples of each profile were examined for their mechanical composition, physical properties consisting of apparent density, real specific gravity, pore space, water holding capacity and volume expansion, total nitrogen, organic carbon, soil reaction, electrical conductivity and soil colour. From the available field and laboratory data a possible explanation has been offered for the genesis of the Nilgiri soils and the soils found in the district characterised as forming a separate group by themselves.
