Determination of microelement and heavy metal content of agricultural land (soils) on the Iğdir-Nakhchivan highway

The lithosphere in the earth and the pedosphere formed thereon are basically composed of a set of elements. Plant nutrients are essential elements for growing of plants. However, some of the micronutrients have a toxic effect when they exceed a certain level. Some toxic elements can also be taken as nutrients by plants when there is a lack of some micronutrients or difficulty in getting them by the plants. In addition, heavy metal emission is carried out in the cultivated agricultural areas, especially in the industrial and highway zones, and the metals in these gases accumulate in the soil and in the plant. In this study, soil samples were taken along the Tuzluca-Iğdır-Nahçivan route, crossing 080 State Highway, at a distance of 0-10-30 meters from the Highway, and at 0-20 cm soil depth. The texture classes, pH, lime, organic matter amounts with the total amount of heavy metal (Pb, Cd) and the total and available amont of micro nutrients (Zn, Cu, Ni, Fe, Mn) of these samples was determined.
