    The effect of EDTA on the extractability of Zinc (Zn), Cadmium (Cd) and Nickel (Ni) in Vertisol and Alluvial soils
    (2002) Adiloglu A.
    Ethylendiamintetraacetic acid (EDTA) is persistent in the environment. The presence of EDTA in soil may alter the mobility and transport of Zn, Cd and Ni in soils because of the formation of water soluble chelates, thus increasing the potential for metal pollution of natural waters. Mobility of metals is related to their extractability. To investigate metal extractability affected by EDTA, Zn, Cd and Ni were added to Vertisol and Alluvial soil at rates of 50, 2 and 5 mg kg -1 , respectively. Both natural and metal amended soils were treated with Na 2 EDTA at rates of 0; 0.2 and 0.5 mg kg -1 . After five months of incubation soil samples were extracted with 0.1 N HCl, 0.005 M DTPA + 0.01 M CaCl 2 + 0.1 M TEA (0.005 M Diethylenetriaminepentaacetic acid + 0.01 M Calcium cloride + 0.1 M Triethanolamine) and 1 M Mg(NO 3 ) 2 , the latter of which extracts the exchangeable from of metald (Zn, Cd and Ni). According to experiment results, Zn, Cd and Ni in all extraction increased with increasing rates of EDTA in the natural and metal amended soils. © 2002, Taylor & Francis Group, LLC.

    The effect of various nitrogen fertilizers on zinc (Zn) availability in non calcic brown forest soils
    (2004) Adiloglu A.; Adiloglu S.; Gonulsuz E.; Oner N.
    In this article the effect of different nitrogen fertilizer application on the availability of zinc (Zn) content in non calcic brown forest soil was investigated. For this purpose increasing rates of NH 4 Cl, (NH 4 ) 2 S0 4 ; NH 4 N0 3 and Ca(N0 3 ) 2 .4H 2 0 fertilizers were applied for having different physical and chemical properties in two soil samples. An incubation experiment was carried out over 4 months. The available Zn content of the soils was determined each month. According to the results the highest available Zn content of the soils was obtained from NH 4 Cl applied to the soils followed by (NH 4 ) 2 S0 4 ; NH 4 N0 3 and Ca(N0 3 ) 2 .4H 2 0 application to soil. At the end of the experiment the average available Zn content of non calcic brown forest soils for NH 4 Cl, (NH 4 ) 2 S0 4 ; NH 4 N0 3 and Ca(N0 3 ) 2 .4H 2 0 fertilizers are 0.93, 0.91, 0.88 and 0.77 mg kg ?1 , respectively. © 2004 Taylor & Francis Group, LLC.

    The effect of zinc (Zn) application on uptake of cadmium (Cd) in some cereal species
    (2002) Adiloglu A.
    It is widely accepted that plants absorb more Cd when they suffer from Zn deficiency, as the Zn deficiency is a critical problem in the world. The effect of increased Cadmium (Cd) application (0 and 15 mg kg -1 Cd) on growing and Cd concentration in some cereal species was investigated at the increasing rate of Zinc (Zn) applications (0 and 15 mg kg -1 Zn). The experiment was carried out under greenhouse conditions using a Zn deficient soil. According to the results, that increased Cd applications severely reduced dry matter production of plants. Dry matter production decreased in the following order: bread wheat > oat > maize > barley. These decreases were determined to be statistically significant (P < 0.01). Cd concentration of cereal species increased with the application of increasing rate of Cd, with a similar trend to that of the dry matter. Dry matter production of plants increased and Cd concentrations of plants decreased with the application of increasing rate of Zn. These results show that Cd accumulation of plant increase in Zn deficient soils. Cd accumulation in plants is hindered with the application of Zn. © 2002, Taylor & Francis Group, LLC.
