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

Abstract

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 and Falluja were selected. two pedons was selected under two environments: desert and alluvial soil, toward vertical in to Euphrates River. Total, available, Crystalline free and Amorphous free, for each iron and manganese was measurement as well as Crystalline form for two elements. statistical analysis by using time series was calculated. The results of the research showed the following: Differentiation of models that describe forms of iron and manganese according for different sedimentation environment as well as heterogeneity of spatial reliability and sampling methods. The method of Semi Variance showed its preference in obtaining the samples and describing the variation of iron and manganese forms compared
