  • Patent number: 11866329
    Abstract: A method for capturing material extracted from biochar is provided comprising the steps of: (i) providing a biochar; (ii) contacting the biochar with an extraction media, where the extraction media causes the removal of residual compounds from the pores and surface of the biochar, creating a resulting extract comprised of the extraction media and removed compounds; and (iii) collecting the resulting extract. The method also can include other steps of extraction and purification. The method further comprises the step of applying the resulting extract to seeds, plants, soil, other agricultural products, or for use in other applications. A biochar having high levels of soluble signaling compounds is also provided, where the biochar is derived from a biomass source that together with predefined pyrolysis parameters produces resulting biochar having increased levels of soluble signaling compounds that are known to increase seed germination rates and early plant growth.

  • Patent number: 11111185
    Abstract: Biochar is provided that is treated to have certain chemical and physical properties found to have the highest impact on plant growth and/or soil health. In particular, the following physical and/or chemical properties, among others, of a biochar have been identified as critical properties to control for in the selection of biomass feedstock, pyrolysis conditions, and/or enhancing treatment to increase biochar performance: (i) bulk density (ii) impregnation capacity; (iii) particle size distribution; (iv) solid particle density; (v) surface area; (vi) porosity; (vii) total porosity; (viii) ratio of macroporosity to total porosity (ix) content of residual organic compounds; (x) content of volatile organic compounds; (xii) ash content; (xiii) water holding capacity; (xiv) water retention capabilities; (xv) levels of dioxins and other potentially hazardous byproducts of pyrolysis; and (xvi) pH.
