The purpose of a soil nutrient inventory is to raise understanding of the soil's potential and limits so that it can be used effectively. Higher yields can be achieved by judicious use of fertilizer in the appropriate amounts. The present study was undertaken to assess the soil fertility status for fertilizer recommendation mapping of paddy in the command area of Hosahalli village tank, Hassan. Fifty-nine composite soil samples were collected covering an agricultural area of 23.94 ha at 40 m grid intervals and analysed for soil reaction, salinity, organic carbon, major and secondary nutrients at laboratory using standard methods. Using Arc-GIS the data generated was processed and mapped. Kriging and inverse distance weighting interpolation method was followed. A raster map was developed using the grid points merged with analysed data and then vector spatial soil fertility maps were generated using Arc-GIS. Fertilizer recommendations based on soil tests help to improve soil fertility and crop output with less fertilizer use. [ABSTRACT FROM AUTHOR] |
