Abstract:
The fertility status of soils under arecanut based cropping systems in Coastal region of Udupi district was studied by GPS based soil survey which was carried out in the farmer’s field in three taluks of Udupi district viz., Udupi, Kundapura and Karkala taluks during the period of 2019 to 2021 in order to know the “Status of micro nutrients under arecanut based cropping systems in the coastal region of Udupi district” by using Arc GIS 10.4 software. Surface soil samples were collected from soils under arecanut based cropping systems in Udupi district and were analysed for physical and micro nutrients. Study revealed that soils are sandy clay loam in texture and soil pH was extremely acidic to strongly acidic range with soil pH ranged from 4.03 to 6.60, organic carbon status is medium to high with normal electrical conductivity. Analytical results showed that DTPA extractable micronutrients like zinc, iron, manganese and copper ranged from 0.02 to 1.04, 10.56 to 29.04, 4.48 to 14.52 and 0.16 to 6.42 mg kg-1. The DTPA extractable micronutrients iron, manganese and copper are found sufficient whereas zinc found deficient in soils under arecanut based cropping systems of Udupi district.
