Short rotation of Miscanthus x giganteus on marginal soil with biochars amendments – leachates of nutrients from plots

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 dataset provides the nutrient contents in leachates from plots collected during the experiment's first vegetative period (May-September 2023). The analyses were performed with the use of cuvette tests and using a spectrophotometric device (DR3900, Hach Lange, USA).
