The distribution pattern of total and available iron and their relationship with different soil properties were studied in twenty three soil profiles representing seven major soil series covering four major soil types of Namakkal Taluk in Tamil Nadu. Total iron content varied from 2.90 to 13.60 per cent and the content increased with depth in all the soils. The available iron content varied from 2.01 to 12.66 ppm and the content decreased with depth in laterite and alluvial soils while irregular pattern was observed in black and red soils. Total available iron had a positive association with organic matter and clay content.
