Two hundred fifty soil samples from Tatrakallu village in scarce rainfall zone of Andhra Pradesh were drawn at 250 m grid interval leaving hills and water bodies and assessed for their fertility parameters. Analytical data was interpreted and statistical parameters like range, mean, standard deviation and coefficient of variation were calculated. Soil fertility maps were prepared for each parameter under GIS environment using Arc GIS v 10.3. Soils were neutral to strongly alkaline with non-saline in nature and soil organic carbon content was low to medium. The available nitrogen (N) was low to medium, available phosphorus (P) and potassium (K) was low to high and available sulphur (S) was deficient to sufficient. Regarding available micronutrients, zinc (Zn) and iron (Fe) were deficient to sufficient whereas, available copper (Cu) and manganese (Mn) was almost sufficient in the soils. The fertility status of nutrients in watershed revealed that, available N, S, Zn and Fe are important soil fertility constraints.
