Abstract

A method for the production of an agent for enhancing soil growth is described, comprising: grinding a biomass feedstock to produce ground biomass particles; subjecting the ground biomass particles to a biofractioning process including an auger reactor; selectively collecting at least one volatile component as it is released from the ground biomass particles; collecting a last remaining nonvolatile component comprising BMF char; rendering a surface of the BMF char hydrophilic; exposing the BMF char to microorganisms; and adding the BMF char to soil.
