Abstract: An investigation was carried out in Tiruchirappalli district of Tamil Nadu where the TNPL is planned to establish a paper board industry (TNPL Unit II) at Mondipatti village of Manaparai taluk. The investigation was carried out to assess the soil fertility status in and around the TNPL unit II to ensure the suitability of soil for different crops. Around 416 soil samples were collected at 200m grid sample interval and its properties including fertility status viz., Available Nitrogen, Phosphorus and Potassium were assessed and their results were interpreted with statistical parameters such as standard deviation, minimum, maximum and mean. The maps were prepared for each parameter under GIS using Arc GIS V 10.1. The soils of area under investigation revealed that they were acidic to strongly alkaline (4.72 to 9.78) with non-saline. The soil Organic carbon content was low to high with value of 1.4 to 10.3 g kg-1 however, 84.8 per cent of area falls under lowest organic carbon status. The available nitrogen status of the samples was low to high with the value of 137 to 639 Kg ha-1 however, 60.3 per cent of area falls under low status, similarly for available phosphorus status also low to high with a value of 9 to 57Kg ha-1however, 58.9 per cent falls under medium status. The available potassium status ranged from low to high with a value of 28to 989 Kg ha-1 however, 50.48 per cent of area falls under high status. Hence, the highest percentage of available N, P & K status of investigated area were falls under low, medium and high status, respectively. Based on the Nutrient Index Value of the study area falls in Low organic matter, medium in available Nitrogen and High in available phosphorus and potassium. Hence, the soil needs to be improved by addition of organic matter for enriching soil available nitrogen status.
