未知. A study was undertaken to evaluate nine soil series belonging to Dotikol micro-watershed in Kalaburagidistrict in North-Eastern Transition Zone of Karnataka for sustainable land use planning. The soil serieswere Chimmanboda (CMB), Chimmanchod (CMH), Chincholi (CNL), Dotikol (DTK), Hasiragundgi (HGD),Karakmukali (KKK), Narnal (NNL), Rummanguda (RMG) and Ranapur (RNP) mapped into twenty mappingunits and soil map was generated using GIS technique. The soils were evaluated for land capabilityclassification, and categorized as land capability classes III, IV and VI based on limitations of erosion,drainage and physicochemical properties. Soil-site suitability assessment reveals that lowland and midlandare moderately suitable (S2) for cultivation of field crops like sorghum, red gram, green gram, bengal gram,black gram and soybean with moderate limitations of drainage and fertility, while upland area is marginallysuitable (S3) for cultivation of these crops. The uplands are not suitable (N) for horticultural crops likemango, guava, sapota, custard apple and jamun, because of severe limitation of depth. Whereas, lowlandand midland, with moderate limitations of rooting depth and texture are moderately suitable (S2) for thesecrops.
