Short & double rotation of Miscanthus x giganteus on marginal soil with biochars amendments - elemental composition of plant biomass

This dataset provides the results of short and double rotations of Miscanthus giganteus on marginal soils. Biochars were added to poor soil to improve its properties. The experimental pots were also fed with alternative fertilizer, which included spent coffee grounds and NPK standard fertilizer. This data set contains the elemental composition results of Miscanthus roots, rhizomes, stems, and leaves gathered at the conclusion of the first and second vegetation periods (September 2023 and September 2024). The analyses were performed with the use of XRF spectrometer (Titan S1, Bruker, USA) using plant measurement and soil configurations.
