While certain heavy metals are vital trace elements for organisms, their excess poses environmental and health risks. Trace elements like copper (Cu) and zinc (Zn) are essential for plant growth and human metabolic functions but become toxic at high levels (Suñer et al., 1999; Kawata et al., 2007).Conversely, major elements such as …

The concentration was 31.0 ± 1.9 mg kg −1 (mean ± 1 SD), which was far lower than those in grapevine leaves (412 ± 7 mg kg −1 for plot G, and 1601 ± 175 mg kg −1 for plot B). Therefore, the influence of compost application on Cu concentration in the studied vineyard soils was neglected in the present study.
