    The Effect of Sewage Sludge Applications on the Growth of Maize (Zea mays L.) and Some Soil Properties
    (Kahramanmaras Sutcu Imam Univ Rektorlugu, 2020) Cakir, Huda Nur; Cimrin, Kerim Mesut
    The aim of this study is to investigate the existing changes for corn yield with the changes on the soil properties after the applications of increased sewage sludge (SS 0 %, 2.5 %, 5 %, 7.5 %, 10 %). While statistically significant decreases were determined in the pH and lime contents of the experimental soil, there were also statistically significant increases for the contents of organic matter and salt of the soil by the effects of applied sewage sludge at the increased doses. The applications statistically increased corn fresh and dry root weights, fresh and dry shoot weights, plant height and diameter compared to the control in the all treatments. It can be concluded that that sewage sludge is not appropriate to use in the agricultural soils in the present form because of very high salt amounts presence in the sewage sludge although there were some positive effects on the plant and soil properties to some great extent with no determined heavy metal toxicity by the application of that sewage sludge into soil at different rates taken freshly from the biological sewage sludge foundation of district Iskenderun of province Hatay.

    Effects of Bio-Bor Fertilizer Applications on Fruit Yield, Antioxidant Enzyme Activity and Freeze Injury of Strawberry
    (Springer, 2016) Gunes, Adem; Turan, Metin; Kitir, Nurgul; Tufenkci, M. Sefik; Cimrin, Kerim Mesut; Yildirim, Ertan; Ercisli, Sezai
    Deficiency of Boron (B) is widespread in the many parts of region of Turkey. So, the effects of boron and plant growth promoting bacteria (Bio-B) on the fruit yield, antioxidant enzyme activity and plant freeze injury of strawberry cv. Fern were investigated under field conditions between 2013 and 2014. The experimental plot was a completely randomized design with 4 replicates. Control and Bio-B were used as fertilizer agent in the experiment. Bio-B fertilizer was applied in three methods as soil, foliar and soil + foliar application methods to strawberry plants. Data through 2 years showed that the use of Bio-B significantly increased fruit yield, antioxidant enzyme activity and decreased freeze injury of strawberry leaf. Soil + foliar applications of Bio-B fertilizer increased to fruit yield compared to the control by 55.91 %. However, foliar application of Bio-B fertilizer increased to catalase (CAT), peroxidase (POD), and superoxide dismutase (SOD) enzyme activity compared with the control treatment 41.86 %, 48.99 %, and 26.59 %, respectively and decreased freeze injury of strawberry leaves 27.41 %. Overall, the results of this study suggest that Bio-B fertilizer application have the potential to increase the yield, antioxidant enzyme activity and decreased freeze injury of strawberry plants under field conditions.

    Heavy Metal Pollution in Soils Adjacent to the Kiziltepe - Viransehir Road
    (Galenos Publ House, 2013) Bilge, Ugur; Cimrin, Kerim Mesut
    The aim of this study is to determine the extent of heavy metal pollution in the soils adjacent to the Viransehir (Sanliurfa)-Kiziltepe (Mardin) highway, and determine the dependence of heavy metal pollution on the distance from the highway. Total of ninety-six surface soil samples (0-15 cm) were collected from the left and right-hand sides of the highway at six different points which were 0, 15, 30 and 60 m apart from the highway in four replicates. The maximum and minimum concentrations of heavy metals in soils were as follows: Pb 0.64-2.24, Cd 0.26-0.40, Ni 27-42, Cr 17-28 and Cu 9.9-14.2 mg kg(-1). Results showed that Pb, Cd, Ni, Cr and Cu contents were higher near the highway. It is therefore concluded that the main source of heavy metal pollution in these soils might be due to traffic. Also, the amount of heavy metals in soils were in the following order: Ni>Cr>Cu>Pb>Cd.

    Nutrient Status of Gaziantep Agricultural Soils and Their Relationships with Some Soil Properties
    (Kahramanmaras Sutcu Imam Univ Rektorlugu, 2016) Karaduman, Abdussamet; Cimrin, Kerim Mesut
    The goal of this study is to determine soil fertility levels of Gaziantep Province, Turkey, through soil analyses. For this objective, a representative soil survey of 53 samplings with two different depths (0-30 ve 30-60 cm), totaling 106 soil samples, was performed to determine soil texture, lime content, soil pH, total salt, soil organic matter content (SOM), cation exchange capacity (CEC), and macro and micronutrient concentrations. The results showed that clayey, clay loam, and sandy clay loam soils covered 65.11, 27.35, and 7.54 % of the study area, respectively. Most of the soil pH measurements in the area fell between slightly alkaline and alkaline reactions. Soil organic matter content was deficient in all the region's soils and approximately half of the soils were categorized as saline soils. Deficiency of nitrogen, phosphorous, potassium, iron, zinc, and cupper was determined in 55.65, 35.86, 39.63, 29.24, 43.4, and 2.8 % of the soils, respectively. Significant relationships were found for lime with pH, Salt, CEC, K, Zn; SOM with P, Salt, CEC, and pH; pH with Zn, CEC, and P; CEC with Clay, Sand, Salt, and P; Clay with K, Sand, and Silt; Sand with Silt and Cu in the soils of the study area.
