Evaluation of Phyto-ashes for Agri-environmental Goals - A Novel Approach

Burning plant biomass is a process accompanying human kind since the early beginning. The residues, i.e., phyto-ashes have been used as potash component or soil improvers, hence they are probably the earliest ever known mineral fertilizers in the human history. The industrial recovery of energy (bioenergy or green energies) by incinerating plant biomass generates huge amounts of phyto-ashes which are recycled for various purposes [1].
