Abstract: Comparison between the three forest types namely moist deciduous, semi evergreen and evergreen of Achencovil forest in the post monsoon season on the basis of soil edaphic factors like gravel, pH, Organic carbon content (OC), Exchangeable Acid (EA), Exchangeable Base (EB), sand, silt, clay and soil chemical factors like Nitrogen, Phosphorous, Potassium, Calcium and Magnesium contents. 20 sites from moist deciduous, semi evergreen and Evergreen were randomly selected. Soil samples of 5×5 cm2 area from a depth of 5 cm were collected from these three habitats. Mean with standard deviation were taken. Habitat wise variation was analyzed by using two way ANOVA. The study shows that the evergreen soil has high nitrogen content (3779.8 ppm). Phosphorous content (5.98 ppm), potassium content (242.45 ppm) and calcium content high in moist deciduous and magnesium (74.75ppm) content high in semi evergreen. The Evergreen soil has high organic carbon content (4.72 %).
