    Assessment of the water quality of Troia for the multipurpose usages
    (Springer, 2007) Ozcan, Hasan; Ekinci, Huseyin; Baba, Alper; Kavdir, Yasemin; Yuksel, Orhan; Yigini, Yusuf
    The aim of this study was to determine the origin and quality of waters in Troia. For this purpose total of 25 water samples including 2 springs, 14 surfaces and 9 groundwaters, were collected at eight different times. Global positioning system (GPS) was used to determine to coordinates of sampling points. The concentration of 6 minor elements (B, Cu, F, Fe, Pb and Zn), 9 major anions and cations (Na(+), Ca(2+), K(+), Mg(2+), SO(4)(2-), PO(4)(3-), HCO(3)(-), Cl(-) and, CO(3)(2-)) were determined by spectrometric, colorimetric and volumetric methods. Water pH, EC, DO, ORP and TDS were measured in situ using probes. The data showed that the concentrations of most of minor elements were below the EPA and TSE limits except Pb which ranged between 0.001 and 4.832 mg L(-1). Statistically significant relationships (P < 0.01 and r > 0.70) were observed between Fe and Cu, Cu and K(+), Cu and Ca(2+), B and Na(+), Na(+) and K(+). Assessing the water based on irrigation using Wilcox model showed that some well waters were not suitable for irrigation. Troia water was found to be highly corrosive and the average corrosion coefficients varied from 0.5 to 4.6. According to the Piper and Schoeller diagrams results, the water in Troia was classified as mixed water type.

    The effect of olive pomace biochar on some characteristics of Vertisols
    (Wiley, 2024) Ilay, Remzi; Bodur, Seda Ozer; Eren, S. Tugce; Kavdir, Yasemin; Ekinci, Huseyin
    The aim of this study was to investigate the effect of olive pomace biochar (OB) application on the mechanical, physical and chemical properties of Vertisols. For this study, soil samples classified as Vertisol in & Ccedil;anakkale, where internal drainage and surface ponding are major problems, were used. The OB was produced at 450 degrees C and then mixed with 0% (control), 3%, 6% and 9% of the soil by weight. Various soil parameters, including the Atterberg limits (liquid limit [LL], plastic limit [PL], plasticity index [PI], shrinkage limit [SL]), saturated hydraulic conductivity (K-sat), field capacity (FC), total carbon (TC) and total nitrogen (TN), were determined. The values of all the soil parameters increased, except for the PI. Moreover, the K-sat value increased by 127% and 136% with 6% and 9% OB application, respectively, compared to that of the control. Additionally, the FC, TN and TC levels in the soils increased in response to biochar application. In conclusion, OB application has a positive effect on the specific properties of Vertisol and can improve its physical properties.
