Iron-Content of Sub-Soils of Ethiope East Local Government Area of Delta State Nigeria

The iron-content of sub-soils of Ethiope East local government area of delta state constitute the study area. Ten soil samples were collected, air dried, sieved and ground into powdered form. The analytical method used was total iron determination method, commonly called Fe-total. This method involves dissolving the soil sample in concentrated hill and heating for several minutes. The Fe 3 originally present was reduced to Fe 2 with Sc 2 while HGd 2 was added to destroy the excess Sncc 2 . The resulting solution for each of the sample was titrated with K 2 , Cr 2 O 7 using a mixture of Hd/H 2 SO 4 and diphenylamine as indicator. The result that sub-soils of the Ethiope East plain containing 0.50% to 1.60% iron. This shows that iron is available in a good amount. The soils have pH value ranging from 4.4 to 7.3 and a good soil texture.
