Soil fertility is a significant natural property which decides the health and quality of land resources. Pulse productivity diminishes nowadays under rain fed condition due to improper nutrient management practices. Hence the present study was carried out to assess the soil fertility status under major pulses growing area by using advanced geo statistical tool with ArcGIS.
Soil survey was taken in 14 revenue villages in Melur block, Madurai district. Soil samples were collected and analysed for its nutrient properties. The Parker’s Nutrient Index and soil fertility maps were prepared by using ArcGIS.
Pulses growing soils were mostly neutral in pH and soluble salt content was low. The organic carbon and available nitrogen content was low to medium. The available phosphorus and potassium status were medium to high. Hence proper nutrient management practices are to be needed for augment pulse production in such area.
