ABSTRACT
To know the spatial distribution of secondary nutrients under different land use system in Hebburu micro-watershed the study was conducted at UAHS, Shivamogga. Under different land use system total 158 soil samples were collected grid wise viz., coconut, arecanut, onion, chilli, ragi, oilseed/ pulse, uncultivable land and other horticultural land use were analysed for their fertility status. The distribution of secondary nutrients viz., exchangeable Ca, exchangeable Mg and available sulphur values in soils ranged from 170 to 52.25 and 0.30 to 26.80 80 cmol (p+) kg-1 and 0.26 to 9.51 mg kg-1. The secondary nutrient status in soils were mapped by GIS technique.
Key words: Watershed, Secondary nutrients, Fertility map, Land use system
