The impact of raw and thermally processed spent coffee grounds on the Miscanthus x giganteus plantation

This dataset includes the results of a pot experiment with marginal soil mixed with spent coffee grounds, as well as biochar made from spent coffee grounds. Miscanthus x giganteus was planted in marginal soil with various soil amendment ratios. The ratios implemented in this experiment are:- for spent coffee grounds: 10%, 20%, and 50% of spent coffee grounds added into soil- for biochar made of spent coffee grounds: 2.5%, 10%, and 30%. The analyses include N,P,K determination in leachates as well as leaf absorptance measurements.
