Abstract:
A study was undertaken to evaluate twenty-one soil series of Ganjigatti sub-watershed of Dharwad district in Northern transition zone (zone-8) of Karnataka for sustainable land use planning. The soil series were AKT (Attikatti), ASR (Adavisomapura), BGD (Bagadgeri), BGH (Bigidigala), BNK (Bhogenagarkoppa), BTP (Bettadapura), GJG (Ganjigatti), HNL (Hirehonnalli), HRG (Harugeri), KDK (Kadanakoppa), KMD (Kamadhenu), KRK (Kuradikeri), MLP (Mahalingpur), MRK (Mishrikoti), MVD (Mevundi), RMN (Ramanala), SDK (Sangedevarakoppa), SGL (Singatalur), SSK (Surashettikoppa), UGK (Ugginakeri) and YSJ (Yelisirur). Based on texture, depth, slope, erosion, graveliness and stoniness, the twenty-one soil series were mapped into sixty-one mapping units by using ArcGIS V 10.8. The soil mapping units were evaluated for potential soil site suitability for major fruits crops viz., mango, guava, pomegranate, sapota, citrus and grapes. The soil series BGD, BNK, KDK, KMD, KRL, MLP, MRK, SDK, SSK and YSJ were currently not suitable for production of mango, guava, pomegranate, sapota, citrus and grapes due to very severe limitations of soil depth and slope per centage. Whereas; AKT, BGH and MVD series are moderately to marginally suitable for cultivation of these six fruit crops. These results could be used as baseline information for identifying specific soil resource constraints for sustainable production of these crops in the study area.
