摘要

The study was conducted to assess the soil fertility status and to prepare the fertility mapping at Rajagondanahallli micro-watershed (480.55 ha) ofDavangere district by using GIS and GPS techniques during the year of 2019 to 2021. Total 44 surface soil samples at 320 * 320 m grid intervals (0 to 15 cm depths) were collected and soil fertility mapping were developed by using Arc GIS software. The fertility status of soils of Rajagondanahallli micro-watershed indicated that the soil were low (81.15 %) to medium (9.58 %) in available nitrogen, low (4.77 %) to medium (85.95 %) in available phosphorus, medium (52.10 %) to high (38.63 %) in available potassium, available sulphur were found to be sufficient, whereas exchangeable calcium and magnesium were found to be sufficient. DTP A extractable zinc was sufficient in 434 ha (90.24 %) and deficient in 2 ha (0.49 %) area. Whereas DTP A extractable iron, manganese, copper were sufficient. Available boron was low (20.19 %) to medium (70.53 %) in the study area.
