A pot experiment was carried out to evaluate the effectiveness of co-situs application of ferric and ferrous iron in alleviating iron deficiency in paddy rice grown (Oryza sativa L.) on calcareous soil. Various ferric and/or ferrous iron containing materials were co-situs applied together with rice seedlings. Plants treated with no iron and ferric iron containing material died by 30 days after transplanting. Materials containing ferrous iron were more effective in alleviating iron chlorosis of paddy rice than those containing ferric iron. In this study, iron deficiency in rice was partially alleviated by co-situs application of all materials that contained ferrous iron in the composition, and the co-situs application of controlled released fertilizer containing ferrous iron was proved to be the most efficient method for improving rice growth in the calcareous soil used.
