Spatial Variation for Iron and Manganese Forms by Using Time Series Analysis Under Different Environments

Six regions in Anbar governorate were selected to study spatial variation of iron and manganese forms using time series analysis under different environments. Al-Baghdadi, Heet, Abu Teban, Ramadi, Khalidiya Falluja selected. two pedons was environments: desert alluvial soil, toward vertical Euphrates River.
