A laboratory experiment was carried out to study the behaviour of added lime.organic matter and fertilizers on the availability on the availability of various forms of iron in two acid alluvial soils.The exchangable iron as well as dilute acid extractable iron were higher in Kallidakurichi soil than in Ambasamudram soil.Both forms of iron increased under water-logging with passage of time.Organic matter addition increased the exchangable iron whereas lime and lime with other treatments influenced the high content of dilute acid extracts iron.A high degree of association was found to exist between pH values and exchangable iron (r=0.459*).
