A survey based study was carried out to assess the secondary and micronutrient availability in grape orchards of Vijayapura taluka of northern Karnataka. Based on the fertilizer nutrient inputs, the grape orchards were grouped into three categories namely, low fertilizer users (n=19), medium fertilizer users (n=26) and high fertilizer users (n=15). The grape orchard soils recorded slightly to medium alkaline soil reactions. Majority of grape orchards soils were observed with high soil organic-C (>0.75%) and none of the soils were found in lower ranges. Among different categories of grape orchards, the available-Ca and Mg contents were found in the order: high fertilizers > medium fertilizer = low fertilizer applied grape orchards. However, available-S contents in three different grape orchard groups were found on par with each other with high available-S contents (> 20 ppm). None of the grape soils showed deficiency of micronutrients except for DTPA-Fe in half of the samples. Distribution of micronutrients in grape soils were found in the order Mn > Zn > Cu > Fe.
