Abstract: A survey study was conducted to know the micronutrient status of Bilagi and Bagalkot taluka. Surface soil samples (n=147) were collected from a grid of 4.5 x 4.5 km2 and analysed for DTPA extractable micronutrients and factors influencing their availability pH and free CaCO3 contents. DTPA extractable micronutrient contents varied among land categories depending on irrigation water sources. Majority of the soil samples representing dryland and borewell irrigated areas recorded lower availability range of micronutrients (except DTPA-Cu). Higher availability range was observed among irrigated land categories. In general, micronutrient availability was observed in the order of dryland < borewell = (canal + borewell) < lift = (lift + borewell) irrigated areas. Across different land categories, the concentration of DTPA micronutrients varied in the order Mn > Fe > Cu > Zn.
