Abstract:
An mapping of soil fertility status was carried out on the soils of Chikkadevarahalli micro-watershed (488.75 ha) during the year 2019 to 2021. Total 48 surface soil samples at 320 × 320 m grid intervals samples at 0 to 15 cm depths were collected and analyzed for it’s totally fertility status and were mapped using Arc GIS software. The mapping the status of soils of Chikkadevarahalli micro-watershed indicated that the soil were low (69.96%) to medium (24.29%) in available nitrogen, low (5.70%) to high (28.74%) in available phosphorus, medium (62.72%) to high (30.93%) in available potassium, low (1.18%) to high (40.39%) in available sulphur, whereas exchangeable calcium and magnesium were found to be sufficient. DTPA extractable zinc was sufficient in 304 ha (62.25%) to deficient in 153 ha (31.40%) area. Whereas DTPA extractable iron, manganese, copper were sufficient. Available boron was low (62.25%) to medium (62.25%) in the study area.
