Application of multidate satellite imagery for land use planning and management in the drought prone areas of Karnataka

Based on visual interpretation of Multidate Landsat Imagery, the spatial distribution of land use/land cover over 45,000 sq.km, spread over the three drought prone districts of Bijapur, Belgaum and Dharwar in NW Karnataka, has been mapped. The land use/land cover is classified into five Level-I and twelve Level-II classes. The pattern of change in land use/land cover during the period October, 1980 and January, 1982 has been one of decline in all the land use classes (except for agricultural use, which is more due to seasonal change) which highlight the land use/land cover changes in the drought prone area.

Manganese status of some soils of Malaprabha river valley project area in Karnataka

The available Mn status in 92 surface soil samples representing 12 major soll series in the Malaprabha river valley project area in Karnataka was studied. The easily reducible Ma is generally high in the soils studied. The low content of readily available Mn can be overcome by the addition of easily oxidisable organic matter to the soils.
