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. Such soluble signaling compounds can then be collected in a biochar extract by contacting the biochar with an extraction media.
Claims (33)
1 . A method for capturing material extracted from biochar, the method comprising the steps of:
providing a biochar that includes soluble signaling compounds;
contacting the biochar with an extraction media, wherein the extraction media removes at least some of the soluble signaling compounds from the biochar, thereby creating a biochar extract containing soluble signaling compounds;
separating at least a majority of the biochar from the created biochar extract; and
collecting the at least a majority of the biochar separated from the created biochar extract and using and/or processing the collected biochar separate from, or prior to, disposal.
2 . The method of claim 1 wherein the at least a majority of the biochar separated from the collected biochar extract are further processed by suspending the collected biochar in a slurry.
3 . The method of claim 2 further including the step of applying the at least a majority of the biochar separated from the created biochar extract to seeds, soil, or plants.
4 . The method of claim 1 where the soluble signaling compounds are karrikins.
5 . The method of claim 4 where the starting biochar has karrikin levels that exceed 10 ng/g.
6 . The method of claim 1 further including the step of infusing the at least a majority of the biochar separated from the created biochar extract with microbes.
7 . The method of claim 1 where the soluble signaling compounds are butenolides.
8 . The method of claim 1 , where the extraction media is water.
9 . The method of claim 1 , where the extraction media is ethanol.
10 . The method of claim 1 , wherein the at least a majority of the biochar separated from the created biochar extract is further processed by introducing a biochar extract back into the separated biochars.
11 . The method of claim 1 wherein the at least a majority of the biochar separated from the collected biochar extract are further processed by particle sizing.
12 . The method of claim 1 further including the step of further using and/or processing the created biochar extract separate from, or prior to, disposal.
13 . A method for capturing material extracted from biochar, the method comprising the steps of:
providing a biochar that includes soluble signaling compounds;
contacting the biochar with an extraction media, wherein the extraction media removes at least some of the soluble signaling compounds from the biochar, thereby creating a biochar extract containing soluble signaling compounds;
separating at least a majority of the biochar from the created biochar extract;
collecting the at least a majority of the biochar separated from the created biochar extract for further use and/or processing separate from, or prior to, disposal; wherein the at least a majority of the biochar separated from the collected biochar extract is further processed into granules.
14 . The method of claim 13 further including the step of applying the at least a majority of the biochar separated from the created biochar extract to seeds, soil, or plants.
15 . The method of claim 13 , where the extraction media is water.
16 . The method of claim 13 , where the extraction media is ethanol.
17 . The method of claim 13 , where the granules are fines.
18 . A method for capturing material extracted from biochar, the method comprising the steps of:
providing a biochar that includes soluble signaling compounds;
contacting the biochar with an extraction media, wherein the extraction media removes at least some of the soluble signaling compounds from the biochar, thereby creating a biochar extract containing soluble signaling compounds;
separating at least a majority of the biochar from the created biochar extract;
collecting the at least a majority of the biochar separated from the created biochar extract; and
applying the at least a majority of the biochar separated from the created biochar extract to seeds, soil, or plants.
19 . The method of claim 18 , where the extraction media is water.
20 . The method of claim 18 , where the extraction media is ethanol.
