Both in light and heavy textured soil, the exchangeable-Fe was decreased significantly with increasing level of P application over control as well as at each successive level of P application. The exchangeable-Fe is the least amongst the inorganic Fe fractions extracted and, on an average, constituted only about 0.02% of total-Fe extracted from the soil irrespective of soil texture. The carbonate-Fe was increased significantly with increasing level of P application up to its highest level over control and also at each successive level. With respect to Fe application, the carbonate-Fe fraction was also found to increase significantly with increasing level of soil application of Fe while foliar spray of Fe did not show any significant influence on carbonate-Fe fraction. This fraction also accounted about 0.02% of total-Fe extracted. With regard to P application, Fe-Mn oxide fraction of light and heavy textured soils was increased significantly with increasing level of P application over control. This fraction constituted on an average 2.6% of total-Fe extracted from the soil. In both light and heavy textured soils, the OM-Fe content decreased significantly with increasing level of P application over control. On an average, this fraction accounted 1.25% of total-P fraction extracted irrespective of soil texture. There was no significant effect of P and Fe application on residual-Fe fraction of light and heavy textured soils. This fraction constituted 2.7% of total-P extracted from soil without consideration of soil texture. Over all study endorse a negative interaction of phosphorus and iron.
