The study was conducted in the plastic house of the Department of Soil Science and Water Resources, college of Agriculture and Forestry / University of Mosul. The study included two experiments:-
The first experiment to study the quality of root exudates produced by plant roots using four type of plants, (wheat, onions, faba bean, clover) had been cultivated in the nutrient solution (Cooper) that contains all the nutrients needed for plants growth during different growth stages. Samples of the nutrient solution for each crop at different stages of development (60،100،150 days). were token. The results showed the presence of reducing sugars and cellulose , hemicellulose, sucrose and disaccharides weakly reduction (glucose, maltose) and Hexose sugar Aldosugar and Hexose sugar ( glucose, fructose) and organic acids at 150 days stage of growth.
The second experiment was conducted to study the available iron and zinc Rhizosphere and Bulk Soil using the four types of crops which had been cultivated in silty clay loam soil from Al-Rashidiya site, Samples of the soil were took to estimated the nutrient concentration (Fe, Zn) in two phases of stages of plant growth (60 days, 120 days). The Results showed increase in Iron and Zinc concentration in the soil rhizosphere and the highest increase in the iron concentration was in the faba bean crop (3.48 mg .kg-1) at the first stage of growth had been noted. In second phase the highest concentration of the Iron was in the soil cultivated crop clover (3.33 mg .kg-1) compared with the control (2.05 mg . kg-1), The highest increasing in available Zinc was in the rhizosphere soil which cultivated with clover crop (0.62 mg. kg-1) at the first stage of growth as compared with the control (0.31 mg.kg-1) increase 100%.
