The study was carried out to the status of micronutrients status (Cu and Zn) in soybean growing soils of Dharwad taluk during 2015-16 kharif season. The study area is situated in Northern Transitional Zone (Zone-8) of North Karnataka. For this purpose fifty one surface soil samples were collected by a systematic sampling strategy (by following standard procedure) at the time of harvesting the kharif crop by using GPS in Dharwad taluk. Surface soil samples (0-15 cm) were collected and subjected to laboratory for analyzing status of available micronutrients viz., Cu and Zn. Based on the average grain yields in 51 fields, the entire group was divided into below average and above average yield categories. Mean yield of 51 fields was 14.67 q ha-1. The study revealed that the available Cu content ranged from 0.31 to 1.22 and with mean value of 0.68 mg kg-1 in below average yield category and in above average yield category ranged from 0.32 to 1.12 and with a mean value of 0.68 mg kg-1. Zinc content ranged from 0.13 to 0.29 and with mean value of 0.19 mg kg-1 in below average yield category and in above average yield category ranged from 0.18 to 1.48 and with a mean value of 0.68 mg kg-1. The soil samples are 100 per cent sufficient in copper and samples are deficient in 86.27 per cent and 13.73 per cent soils are sufficient in zinc.
