A study was under taken to assess the available (DTPA-extractable) zinc and iron in soils under rice based cropping system in Chamarajanagar district, Karnataka. Results of the study indicated that the soils were sandy clay loam in texture with neutral to alkaline pH (6.6 to 9.2). The organic carbon content of these soils ranged from 0.12 to 1.05 per cent. Calcium carbonate content varied from 3.62 to 8.75 per cent and DTPA-zinc and iron varied from 0.69 to 2.96 mg kg-1 and 6.09 to 32.14 mg kg-1. Correlation studies indicated that available zinc recorded a significant and negative correlation with clay (r=-0.24*) and iron recorded a significant and positive correlation with CaCO3 (r=0.54**) and negatively with pH of the soils (r=-0.50**).
