### Heavy Metal Contents
When the Zn level of irrigation water was examined in strawberry-growing regions, the highest Zn content was 106.18 ppm at station 3 in water samples taken from organic farming areas and 120.22 ppm at station 10 in samples taken from conventional farming areas. Comparing the water samples taken from the organic and conventional production areas in terms of total Zn content, the Zn level was found to be higher in the water samples taken from the conventional farming areas (Figure 2a). This affected the Zn content of the fruits, and the Zn contents of the fruit samples taken from the conventional plots were found to be higher than those of the organic plots. The highest Cu content was 37.55 ppm at station 8 in the water samples taken from the regions where organic farming is carried out and 79.25 ppm at station 10 in the samples taken from the regions where conventional farming is practiced (Figure 2b). When the water samples taken from the organic and conventional production areas were compared in terms of total Cu content, the Cu level was higher in the water samples taken from the organic farming areas. The average values of Cd and Pb in the analysis of organic and conventional strawberry fruit samples were below the detection limit. When the Pb level of irrigation water was examined in strawberry-growing regions, the highest Pb content was 28.37 ppm at station 3 in water samples taken from organic farming areas and 9.29 ppm at station 8 in samples taken from conventional farming areas (Figure 2c). When the water samples taken from the organic and conventional production areas are compared in terms of total Pb content, the Pb level is higher in the water samples taken from the organic farming areas. \begin{table}

Table 10: Effects of different seasons and cultivation practices on strawberry Cu content (ppm). The heavy metal (Zn, Cu, Pb, Cd) contents of different organic and conventional stations soils are shown in Figure 3. Since heavy metals are transported from soil to strawberries through the roots and stems of plants, soil is considered one of the important sources of pollutants. The fact that the average concentrations of different heavy metals (Zn, Cu and Pb) were lower than the risk screening values show that the general heavy metal pollution in Huyuk soils where organic and conventional strawberry cultivation is carried out is not a serious problem.
