This study deals with the nutrient status of soil profiles collected from different forest types of the southern Western Ghats falling within the north-eastern part of the Idukki district. Ten locations were selected for the present study; altitude of the region varies from 150 to 2000 m above mean sea level. The vegetation pattern of the area is composed of evergreen, semi evergreen, hill top evergreen, dry deciduous, moist deciduous, sandal wood, shola (tropical montane forest) and grasslands. Shola forests register higher nutrient (especially N and K) status while dry deciduous forest records lower values. The N, P, K status of the forest soils varies from 0 to 1.09%, 0.04 to 0.92% and 0.56 to 3.81% respectively. N and P shows decreasing trend with increasing soil depth and K shows more or less same values throughout the entire depth of the 1 m length profiles.
