Introduction. Copper (Cu) is an essential micronutrient that is important to plants, animals, and humans as a constituent of several enzymes and as a redox catalyst in a variety of metabolic pathways (Citation Devez et al. 2005).The deficiency of Cu may result in reduction of biological function and potentially death.

Copper is not readily mobile in plants and root concentration is considered to be a good indicator of the plant copper content. It has been assumed that the factors affecting metal fractionation and bioavailability in soil include root-induced pH changes, metal binding by root exudates, root-induced microbial activities and root …

Mobile copper. Concentrations for the mobile copper fraction (SI-Fig. 2) ranged between 0.5 and 2.2 µg∙g-1 and showed a slight decrease with increasing treatment copper concentration. However, neither treatment concentration, plant, depth nor their interactions significantly affected mobile copper concentration (p > 0.05).

Young plants may contain 3.00 to 5.00 percent K, although the actual requirement may not be that high. Because it is mobile in the plant, K deficiency symptoms appear in the older plant tissue first. The K concentration in the plant decreases with age. Potassium balance in plants is important.

The decline in plant biomass is the most usual indication in plants under high Cu stress (Nazir et al., 2019). The biogeochemical cycling of Cu in soil-plant-human system is regarded as the base of Cu cycling in living organisms. However, the Cu concentration in plants parts is allied with the soil Cu concentration (Fig. 1).

4.2 Plant Tissue Analysis The copper content of most plants is generally between 2 - 20 mg/kg Cu. For a wide variety of plants, copper deficiency occurs where copper levels are less than 5 mg/kg Cu in the leaf dry matter. Copper deficiency may also occur in grazing animals if the copper concentration in the pasture is below this concentration.
