    Assessment of relationship between geochemical fractions of barium in soil of cherry orchards and plant barium uptake and determination by inductively coupled plasma optical emission spectrometry
    (Atomic Spectroscopy Press Limited, 2019) Sungur, A.; Gur, E.; Everest, T.; Soylak, M.; Ozcan, H.
    This study was conducted to investigate the relationship of geochemical fractions of Ba in soils of cherry orchards and in plant Ba uptake. The levels of Ba in the soil samples were determined after sequential extraction procedure and analysis by inductively coupled plasma optical emission spectrometry (ICP-OES). At the same time, the levels of Ba in cherry leaf samples were determined after a wet digestion procedure by ICP-OES. Soil total Ba concentrations (mean 108.9 µg g-1) were found within normal ranges specified for agricultural soils. The Ba concentration in the cherry leaf samples was found in the range of 9.1 µg g-1 to 20.6 µg g-1. Sequential extraction revealed that Ba existed in highly mobile phases (42%), which are attributed to anthropogenic sources as well as to decomposition of soil parent material. The experimental data were subjected to hierarchical cluster analysis to assess the relationship between the Ba concentration of each fraction and the leaf Ba contents. A significant correlation was observed between the leaf Ba concentrations and the acid soluble fraction. © 2019, Perkin - Elmer Corp. All rights reserved.

    Assessment of Relationship Between Geochemical Fractions of Barium in Soil of Cherry Orchards and Plant Barium Uptake and Determination by Inductively Coupled Plasma Optical Emission Spectrometry

    This study was conducted to investigate the relationship of geochemical fractions of Ba in soils of cherry orchards and in plant Ba uptake. The levels of Ba in the soil samples were determined after sequential extraction procedure and analysis by inductively coupled plasma optical emission spectrometry (ICP-OES). At the same time, the levels of Ba in cherry leaf samples were determined after a wet digestion procedure by ICP-OES. Soil total Ba concentrations (mean 108.9 mu g g(-1)) were found within normal ranges specified for agricultural soils. The Ba concentration in the cherry leaf samples was found in the range of 9.1 mu g g(-1) to 20.6 mu g g(-1). Sequential extraction revealed that Ba existed in highly mobile phases (42%), which are attributed to anthropogenic sources as well as to decomposition of soil parent material.

    Spatial and Temporal Variation of Available Zinc of Troy (Kumkale) Soils
    (Univ Namik Kemal, 2012) Sungur, A.; Everest, T.; Ozcan, H.
    In this study spatial and temporal variation of available zinc of Troy region (Kumkale plain) which has important potential in Canakkale was studied. In the study, 153 soil samples from 51 distinctive surface (0-25 cm) was taken in three different sowing periods (December - April - July). The amount of available zinc has shown temporal variation because of the climatic factors and it has shown spatial variation due to the soil properties. While available zinc was over the adequate limits in December, in April and July at some sample points available zinc was under the adequate limits. Hence, these distribution maps produced by geographical information system (GIS).
