In view of wide spread micronutrients deficiencies, soils of Bhanapur microwatershed in northern dry zone of Karnataka were studied for their availability and mapped by GIS technique. Twenty-five surface soil samples from black soils and seventy-five surface soil samples from red soils were collected to assess the available micronutrient status in the microwatershed. DTPA extractable Fe, Mn, Zn and Cu were found to be adequate in major part of the area. Mapping of available micronutrients status by GIS technique revealed that, out of 581.96 ha area of microwatershed, 85.46ha was in deficient category, 61.06 ha in sufficient category and 435.44ha in excess category with respect to available Fe status. The entire study area was sufficient in available manganese. Major portion of the study area (349.94 ha) was under sufficient rating for available zinc status and deficiency of the available Zn was found in 232.02 ha. Available copper content of the study area was under both sufficient (342.34 ha) and deficient (239.62 ha) ratings.
