Abstract: 

Introduction: Among essential plant micronutrients, iron (Fe) exerts the highest restriction to crop production in Fars Province. Determination of iron chemical forms is one of the accurate methods to study the status of this element (Fe) in the soil. Assessment of the relationships between the chemical forms and soil characteristic helps to describe the chemical changes of iron in the soil. In this study sequential extraction to determine iron forms in soils was conducted in order to provide a clear understanding of elements mobility and availability to plants. Trace elements in the soil are classified into 5 groups of chemical forms. These are the water-soluble and variable, adsorbed, chelate creating with complex compounds, secondary clay minerals, forms of insoluble metal oxide minerals, and primary minerals. Trace elements in the forms of water-soluble, changeable, adsorbed or chelates improve elemental balance in the soil and are known important for plant nutrition.
