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 is a solvent other than water and removes at least some of the soluble signaling compounds from the biochar, thereby creating a biochar extract containing soluble signaling compounds;
collecting the biochar extract and further processing the biochar extract to remove the majority of biochar particles.
 
8. 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 is a solvent other than water and removes at least some of the soluble signaling compounds from the biochar, thereby creating a biochar extract containing soluble signaling compounds;
collecting the biochar extract and further processing the biochar extract to concentrate the soluble signaling compounds.
 
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 is a solvent other than water and removes at least some of the soluble signaling compounds from the biochar, thereby creating a biochar extract containing soluble signaling compounds;
collecting the biochar extract; and
applying the biochar extract to seeds, soil, or plants.
 
16. 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;
collecting the biochar extract and reincorporating the biochar extract into a biochar.
