Knowledge of spatial variability in soil fertility is important for site specific nutrient management. In this study, spatial variability in properties that influence soil fertility such as soil organic carbon (OC), available N, available P2O5 and available K2O, secondary and micro nutrients in surface soils (0-30 cm depth) of 67 farmers' fields of Alanatha Cluster Villages, Kanakapura Taluk, Ramanagara District, Karnataka (India) were quantified and the respective thematic maps were prepared on the basis of ratings of nutrients. Arc Map with spatial analyst function of Arc GIS software was used to prepare soil fertility maps. |
