Abstract
A study was conducted to evaluate the availability of iron in some Babylon governorate soils and their contents in corn plants. Thirteen different locations were selected; the selections were made to represent the most local geographical units dominated in Governorate in soils and were 27 units. Since the locations were differed in areas, accordingly differed in number of soil samples. Linear equations were used to describe the relationship between the studied parameters and some properties of soils. The results showed that, the availability of iron was ranged from 0.26 to 12.60 with average of 4.96 mg Kg-1.With respect to plant dry matter, the data indicated that iron content was ranged from 16.22 to 166.31 with average of 49.73 mg Kg-1. The percentage of locations suffered from iron deficiency was 82%. With the exception of AL_Sadda soils, all locations were low in available iron, moreover locations of Al_Abrahimyia and Abu-Garak were the least in available iron with percentages of 100 and 98% respectively. The results also showed a negative linear relation between available iron and iron content in plant with total and active carbonate minerals, whereas a positive linear relation between available iron was found with cation exchange capacity (CEC), however no significant relation was found with pH, organic matter, clay and silt content.
