Elemental composition of Miscanthus giganteus cultivated on soil amended with processed spent coffee grounds

This data set contains the elemental composition results of Miscanthus giganteus roots, stems, and leaves. Samples were collected after medium-term screening (42 days) of Miscanthus planted in marginal soil with various soil amendment ratios (for spent coffee grounds: 10%, 20%, and 50% of spent coffee grounds added into soil and for biochar made of spent coffee grounds: 2.5%, 10%, and 30% v/v).
Elements such as Mg, Al., Si, P, S, Cl, K, Ca, Cr, Mn, Fe, Ni, Cu, Zn, As, Mo, Cd, and Pb were detected. The multi-elemental composition was determined using non-destructive analytical method: X-ray fluorescence (XRF, Titan S1, Bruker, USA). The certified materials LGC7162 (strawberry leaves) were utilized for method calibration.
