Patent number: 11866329Abstract: 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.Type: GrantFiled: December 17, 2018Date of Patent: January 9, 2024Assignee: Talipot Cool Extract (IP), LLCInventors: Han Suk Kim, Matthew William Smith, Haijun Wan, Richard W. Belcher, Ranko Panayotov Bontchev, Brian Buege
