A pot culture experiment was carried out to assess the influence of soil added copper (Cu) on the availability and transport of mineral nutrients (MNs) such as Na, K, Ca, Mg, P and N. The results showed that the influence of Cu in the rhizosphere environment on the dynamic behavior of mineral nutrients is concentration dependent. Increasing levels of Cu in the soil increases the availability of Na, K, Mg and P. whereas the availability of Ca was affected. As far as the mobility of MNs is concerned, Cu in soil increases the soil to leaf mobility of Ca and N, whereas it affected the mobility of Na, K and Mg. The influence of Cu on the mobility of P from the soil to leaf shown to be neutral.
