Geographical Information System (GIS) based soil fertility maps for the Agriculture College and Research Institute, Vazhavachanur farm in order to find out the soil fertility related production constraints of the farm and to suggest corrective measures for optimum production of crops, Totally 35 numbers of soil samples were collected from the Agriculture College and Research Institute, Vazhavachanur farm. The synchronization points were recorded by the help of GPS instrument (Garmin). Base map of the Agriculture College and Research Institute, Vazhavachanur farm was digitized and geo-referenced. Polygons were overlayed on the geo-referenced map. The average value of the pH and EC is the 6.95 and0.34 dS m-1. The organic carbon content of the soil is very much low 0.31. The available nitrogen, phosphorus and potassium content of the soil is 190 kg ha-1 (low), 18 kg ha-1 (medium) and 203 kg ha-1 (medium) respectively. The available Iron, zinc, Manganese and Copper in the soil 7.28 ppm (high), 0.70 ppm (low), 1.24 ppm (low),1.02 ppm (low) respectively.
