Abstract: Comparison between agriculture land and grass land habitats in Alapuzha district on the basis of soil edaphic factors like temperature, pH, Organic carbon content (OC), moisture content, Exchangeable Acid (EA), Exchangeable Base (EB), sand, silt, clay and soil chemical factors like nitrogen, phosphorous, potassium, calcium and magnesium contents.20 agricultural land site and 20 grass land sites were selected. Soil samples of 55 cm2 area from a depth of 5 cm were randomly collected from agriculture and grass land habitats. Monthly samples were collected and pooled into four seasons like pre monsoon, monsoon post monsoon and summer. Mean with standard deviation were taken. Seasonal and site wise variation were analyzed by using two way Anova. The study shows that the agriculture land soil has high nitrogen content (2844.83 ppm), Phosphorous content (10.24 ppm), and potassium content (144.2 ppm). The grass land soil has high organic carbon content (4.56 %), calcium content (1564.43ppm) and magnesium content (292.84 ppm).
