Pedogenic Forms of Iron and Manganese and Its Implication on Soil Genesis Over a Lithosequence in Nigeria
The citrate-bicarbonate-dithionite extractable iron and manganese oxides (Fed and Mnd), oxalate extractable iron and manganese oxides (Feox and Mnox), sodium pyrophosphate extractable iron and manganese oxides (Fep and Mnp), active iron and manganese oxide ratios (Feox/d and Mn ox/d) and Clay/dithionite iron ratio (clay/ Fed) were evaluated in soil...
