The invention provides for methods, devices, and systems for pyrolyzing biomass. A pyrolysis unit can be used for the pyrolysis of biomass to form gas, liquid, and solid products. The biomass materials can be selected such that an enhanced biochar is formed after pyrolysis. The biomass can be pyrolyzed under specified conditions such that a selected biochar core is formed. The pyrolysis process can form a stable biochar core that is inert and/or resistant to degradation. The biochar or biochar core can be functionalized to form a functionalized biochar or functionalized biochar core. Functionalization can include post-pyrolysis treatments such as supplementation with microbes or physical transformations including annealing and/or activation.

A biochar that is usable for growth of an organism in soil, comprising a biochar core comprising (i) a porosity that is less than or equal to about 0.9 of a total volume of said biochar core, (ii) a surface area greater than or equal to about 1 m2 per gram or less than or equal to about 5000 m2 per gram, and (iii) pores with average pore sizes less than or equal to about 400 micrometers, wherein said biochar core has increased capacity to hold a nutrient or biological energy source relative to a biomass precursor of said biochar core.
