Assessment of nutrient status in Rajagondanahallli Micro-watershed of Channagiri taluk, Davanagere district, Karnataka by using geographic information system technique

Abstract

The study was conducted to assess the soil fertility status and to prepare the fertility mapping at Rajagondanahallli micro-watershed (480.55 ha) of Davangere 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. DTPA extractable zinc was sufficient in 434 ha (90.24 %) and deficient in 2 ha (0.49 %) area. Whereas DTPA extractable iron, manganese, copper were sufficient. Available boron was low (20.19 %) to medium (70.53 %) in the study area.

Keywords: arc GIS software, mapping and micro-watershed and soil fertility
