Abstract:Acidity limits plant growth, particularly when the growing medium has a pH below 5, a challenge that is particularly relevant for certain plants like switchgrass (Panicum virgatum). Although adding biochar to the growing medium has been shown to improve plant growth by modulating acidity, its specific impact on switchgrass remains largely uninvestigated. Thus, we conducted a pot experiment to assess how different biochar application rates (0%, 1%, 2.5%, 5%, 10%, and 20% w/w), derived from mushroom residue thro… Show more
