Urmia University Applied Soil Research 2423-7116 5 2 2018 02 20 Effects of copper application on concentration and uptake of copper (Cu), manganese (Mn), potassium (K) and phosphorus (P) on corn Effects of copper application on concentration and uptake of copper (Cu), manganese (Mn), potassium (K) and phosphorus (P) on corn 122 134 20514 FA Adel Reyhanitabar Journal Article 2017 01 28 Copper (Cu) is an essential micronutrient for plant growth and a potentially toxic heavy metal. Copper application can have a significant impact on Mn, K, P and other nutrients role in plants nutrition. In this study checked out the effect of applied Cu on corn (Zea mays L.) growth, concentration and uptake of Cu, Mn, K and P in 21 calcareous soils. To measure the concentration and content of the nutrient of the study, in a greenhouse experiment, corn plant (Zea mays L.) single cross 704 variety cultivated in two levels of Cu, zero (control) and 7.5 mg Cu kg-1 soil as CuSO4.5H2O. The experiment was carried out as factorial in a randomized complete blocks design with three replications. According to the results, by application of copper, significant (p Copper (Cu) is an essential micronutrient for plant growth and a potentially toxic heavy metal.
